Description

2.1 Reliability and Quality Standards

Congratulations on your purchase of the PowerWAVE 9000 DPA UPS.
By using a unique modular construction and incorporating the latest technological developments in power

engineering, the PowerWAVE 9000 DPA represents a compl etely new generation of transformer-les s 3
phase UPS-System. High reliability, upgrade ability, low operating cost and excellent electrical performance
are just some of the highlights of this innovative UPS solution.

Kohler Uninterruptible Power specialises in the design, building, installation and maintenance of
Uninterruptible Power Systems. This compact and powerful UPS is just one example of our wide range of
state of the art power protection devices and will provide your critical equipment with a steady and reliable
power supply for many years.

The criteria and methods which are used in the design, manufacture, and maintenance of Uninterruptible
Power Supply systems are certified to International Standard ISO 9001/EN 29001. A full UPS Specification is
given in Chapter 8 of this manual.

2.2 PowerWAVE 9000 DPA System

PowerWAVE 9000 DPA is a truly modular system based on a range of 10kVA to 45kVA UPS power modules
that can be connected in parallel to form a redundant-module system. Th e UPS module s are hou sed in free­standing cabinets which are purpose designed to contain up to one, three or five modules. Two cabinet
ranges are available as standard – the ‘MD’ cabinet range is designed for use with 10kVA-25kVA modules
(see Figure 2.2), whereas ‘MX’ cabinets are used with modules from 30kVA to 45kVA (see Figure 2.3).

Cabinets designed for three (or fewer) modules also contain the UPS batteries; however an additional,
external battery cabinet can be used to extended the battery autonomy time if required. An external battery
cabinet is always required for cabinets designed for 5 UPS modules. A range of battery cabinets of matching
style and colour is available to sit alongside the UPS cabinets to provide a matching suite.

2.3 System Configuration

The PowerWAVE 9000 DPA system configurations are described below.

2.3.1 Single/Parallel module configurations

Within the UPS cabinet, the power modules can be configured in one of two ways:

Single-module system

As its name suggests, a ‘single-module’ system comprises a cabinet fitted with just one UPS module, even if
the cabinet is designed to house several modules – for example a TRIPLE DPA-75 or -150, UPGRADE DPA­125 or -250 fitted with a single module is still considered as a ‘single’ module system.

Parallel-module system

A ‘parallel-module’ system employs several modules (of the same rating) operating in parallel within the
same cabinet (e.g. TRIPLE DPA-75) using the DPA technology (see paragraph 2.4.4).

Key Point: All the modules fitted within a cabinet must be of the same rating – i.e . it is no t possible
to mix 10kVA and 20kVA modules in the same parallel system.

2: Description

2-2 UPS306-01-00 PowerWAVE 9000 DPA User Manual Dated 01-06-2010

2.3.2 Single/Multi cabinet configurations

Single cabinet system

A single-cabinet system comprises a stand-alone cabinet containing one or more UPS power module(s)
operating as a single-module or module-module system (as defined in paragraph 2.3.1).

Multi-cabinet system

To further increase the overall system capacity it is possible to connect up to 10 standard cabinets in parallel.
Depending on the model type, each cabinet ca n contain up to 5 UPS power modu les, thereby potentiall y
resulting in a system comprising up to 50 parallel modules if 10x UPGRADE DPA-125 or 10x UPGRADE
DPA-250 cabinets are employed. Although, in practice, a typical multi-cabinet system will be made up of
fewer than 10 cabinets.

Every standard PowerWAVE 9000 DPA cabinet is provided with the parallel option, eliminating any need fo r
time-consuming or expensive upgrading on site.

Figure 2.1 PowerWAVE 9000 DPA UPS Multi-Cabinet Chain.

The multi-cabinet configuration is based on a Decentralised Bypass Architecture (DPA) – i.e. every UPS is
provided with its own static bypass. In a parallel system there is always one master module and the other
modules are slaves. If at any time the master goes faulty the next UPS (former slave) will immediately take
over the master function and the former master will switch off.

2.3.3 ‘Redundant-module’ versus ‘Capacity’ system

The difference between a ‘redundant-module’ system and a ‘capacity’ system is that a ‘capacity’ system is
rated such that ALL the UPS power modules are required to provide the necessary output load power. This is
not the case for a ‘redundant-module’ system, whereby the overall system is designed with one (or more)
modules over and above that required to supply the full load. In a redundant-module system it is therefore
possible to lose one (or more) UPS module without affecting the load supply.

Every UPS power module in a parallel configuration is provided with an output parallel Isolator (IA2) which,
when opened, isolates the corresponding module from the parallel system and the module no longer
contributes to the system’s power output. In a ‘capacity’ system opening this isolator this will cause the load
to transfer to the (unprotected) bypass supply. but in a ‘redundant-module’ system the load will continue to
receive protected power until the number of off-line modules exceeds the inb uilt system redun dancy.

2.4 Advanced Design Features

2.4.1 Hot-swappable modules

In a redundant module system (see paragraph 2.4.4) the unique Hot-Swappable feature enables a UPS
module to be inserted or removed from the larger cabin et assembly whilst it is still powere d (hot) without
affecting the supply to the load, and without having to transfer to bypass.

Note: In a non-redundant configuration the load will unavoidable have to be transferred to bypass while a

module is removed from the system.

2.4.2 Advanced booster technology

The UPS module’s inbuilt advanced booster technology results in a perfect sinusoidal in put power quality at

0.99 input power factor with a harmonic content of less than 3% THD(i). This leads to a more re liable total
system operation and savings in generator and transformer sizing as winding losses are minimised. It also
means that traditional harmonic filters are no longer required.

2: Description

The high power factor presented by the UPS on the incoming mains supply minimises cabling and fusing
costs due to the resulting lack of reactive power consumption. This, together with the accompanying low
harmonic currents, provide the following benefits:

• No additional losses in wires and cables.

• No extra heating of transformers and generators.

• No over sizing of generators.

• No false circuit breaker tripping and malfunction.

• No erratic operation of computers, telecommunication, monitors, electronic test equipment etc.

• No resonance with power factor correction capacitors.

2.4.3 Flexible battery management (FBM)

This equipment employs a flexible battery management which avoids premature deterioration of battery life
by advanced management of battery charging and preventive failure diagnostics.

The major benefits are:

• AC-ripple free battery charging due to a dc-dc charger separated from the rectifier and inverter.

• Wide range of number of battery blocks (30-50 blocks of 12V; depending autonomy times).

• UPS's wide input voltage operating window extends the battery life due to fewer discharge cycles.

• Battery discharge protection caused by load jumps.

• Proactive battery protection from false manipulations and inadequate charging voltages.

• Proactive battery failure detection thanks to Advanced Battery Diagnosis (ABD) - Algorithm.

• User selectable battery tests.

• Optional temperature compensated charging to enhance battery life.

2.4.4 Decentralized Parallel Architecture (DPA)

In a ‘redundant’ parallel UPS system the UPS modules are linked together in parallel so that in the event that
one module fails the others can automatically sustain the load supply.

A ‘parallel redundancy’ configuration i s achieved by having a rand om or fixed master-slave relationsh ip
among the UPS modules whereby the master logic gives out individual commands to all the slave units.
Unfortunately, in some designs this can lead to a single-point-of-failure for the entire system if the master
logic or communication to the slaves fails.

The PowerWAVE 9000 DPA system features DPA paralleling technology that provides n+x redundancy
without introducing a single-point-of-failure. The modules utilizing the DPA technology are completely
autonomous by means of individual power units, bypasses, CPUs, control panels and separate battery
configuration.

DPA technology uses multi-master logic with separated independent regulation and logic buses to maintain
the highest system availability.

This unique decentralized design:

• enables a parallel redundant system providing 100% conditioned power at all times.

• eliminates the system-level single point of failure inherent in traditional parallel UPS

• exponentially increases the reliability of the overall system.

• allows up to ten UPS cabinets to supply the same load in parallel and redundant configuration.

Installation

3.1 Introduction

This chapter contains all the information necessary for the correct unpacking, positioning, cabling a nd
installation of the PowerWAVE 9000 DPA.

3.2 Receipt of the UPS

The UPS and accessories are delivered on a specifically designed pallet that is easy to move with a forklift or
a pallet jack.

The packing container protects the UPS from mechanical and environmental damage. This protection is
further increased by wrapping the PowerWAVE 9000 DPA UPS with a plastic sheet.

Upon receiving the UPS, carefully examine the packing container and the UPS for any sign of physical
damage. The outside 'Tip&Tel' (“FRAGILE” and “ARROW”) indicator should be intact if the equipment has
been transported in an upright position. In case of rupture (or if they are suspect) inform the carrier and
Kohler Uninterruptible Power immediately.

Ensure that the received UPS corresponds to the descripti o n i ndi ca te d in the delivery note.

3.2.1 Site transportation

If you transport the UPS equipment after it has been off-loaded (for example, for storage or moving to a
different installation location) please observe the following precautions.

WARNING: All the operations described in this section must be performed by authorised
electricians or suitably qualified personnel.
Kohler Uninterruptible Power will take no responsibility for any persona l or material damage
caused by incorrect cabling or operations, or activities which are not carried out in strict
accordance with the instructions contained in this manual.

CAUTION: When off loading the UPS always keep it in an upright position.
Do not drop the equipment.
Do not stack the pallets due to the high-energy batteries involved and the heavy weight.

CAUTION: Visible transport damages must be claimed to the carrier immediately after receipt!
Other claims for shipping damage must also be filed immediately and the carrier must be
informed within 7 days of receipt of the equipment.
Packing materials should be stored for further investigation.

CAUTION: Transportation:
To avoid the UPS cabinets and/or battery cabinet falling over, use the shipping brackets on the
rear and front to secure the cabinets.
– Do not tilt the cabinets more than 10° from vertical.

CAUTION: Potential dangers:
– If the cabinet has been tilted it might damage the equipment and it should not therefore be
connected to the mains electricity supply.
– The weight of the UPS system could cause serious injuries to persons or anything in the
surrounding area.

3.3 Unpacking

If the packages are received in good order (i.e. the ‘tip & tell’ “FRAGILE” and “ARROW” indications on the
packing container are intact) then perform the following steps to unpack the UPS:

1. If the cabinet is shipped inside a wooden case, remove the screws at the base and sides of the case then
carefully remove the case from the equipment.

2. Cut the wrappers and remove the packing container by pulling it upwards.

3. Remove the plastic sheeting covering the UPS.

4. Remove the UPS from the pallet.

5. Retain the packaging materials for future shipment of the UPS.

6. Examine the UPS for any sign of damage.
Notify your supplier immediately if damage is apparent.

7. Open the cabinet door and ensure that all the UPS modules are correctly and securely fitted in their
compartments. Ensure that a pr otection cover is fitted to the front of any empty UPS compar t me nts.

3.3.1 Nameplate

The technical specifications of the PowerWAVE 9000 DPA are provided on the nameplate which is situated
at the front (internal door) of the UPS.

Check that the details on the nameplate corresponds to the purchased material detailed on the delivery note.

3.4 Batteries

The standard batteries connected to the UPS are sealed, maintenance-free batteries which will be mounted
either within the UPS cabinet or an external battery cabinet. The b attery will usually be con nected when the
UPS is commissioned.

Battery life depends very much on the ambient temperature, and optimum battery life will be obtained if the
batteries are operated at a temperature of 20°C.

If the UPS is delivered without batteries, Kohler Uninterruptible Power is not responsible for any damage or
malfunctioning caused to the UPS by the incorrect storage, installation or connection of batteries by third
parties.

CAUTION: Storage:
– The UPS should be stored in the original packing and shipping carton.
– The recommended storing temperature for the UPS system and batteries is between +5 °C
and +40°C.
– The UPS system and the battery sets must be protected from humidity
< 90% RF (non-condensing).

WARNING: T he UPS system, the battery cabinet (option) and the batteries are heavy and
may tip during transportation causing serious injury if the unpacking instructions are not
followed closely.

UPS306-01-00 PowerWAVE 9000 DPA User Manual Dated 01-06-2010 3-3

3: Installation

3.5 Storage

3.5.1 UPS

If you plan to store the UPS prior to use, store it in a clean dry environment with a temperature between 5°C
to +40°C and RH of less than 90%. If the packing container is removed, you must protect the UPS from dust.

3.5.2 Battery

The UPS utilizes sealed, maintenance-free batteries, whose storage capability depends on ambient
temperature. It is therefore important not to store the UPS for longer than 6 months at 20°C, 3 months at
30°C or 2 months at 35°C storage temperature without recharging the batteries. For longer term storage the
battery should be fully recharged every 6 months @20°C.

3.6 Positioning

3.6.1 Planning the installation

A certain amount of pre-planning will help ensure smooth, trouble-free equipment installation. The following
guidelines should be taken into account when planning a suitable UPS location and environment.

1. The equipment must be installed and transported in a upright position.

2. The floor at the installed location and en-route from the off-loading point must be able to safely take the
weight of the UPS and battery equipment plus fork lift during transit.

3. The UPS cabinet requires space to bottom/front and back to enable cooling airflow. Suitable ventilation
airflow must also be provided (See Figure 3.1). Allo w a 200mm minimum clearance at the back of the
cabinet.

4. All parts of the UPS required for maintenance, servicing and user operation are accessible from the front.
Reserve a minimum of 1000mm space at the front of the UPS cabinet.

5. An ambient temperature of 20°C is recommended to achieve a long battery life. T he cooling a ir entering
the UPS must not exceed +40°C.

6. Avoid high ambient temperature, moisture and humidity. The floor material should be non-flammable and
strong enough to support the heavy load.

7. In summary, the UPS should be located where:
a) Humidity (< 90% non-condensing) and temperature (+15°C to 25°C) are within prescribed limits.

b) Fire protection standards are respected.
c) Cabling can be performed easily.
d) A minimum 900mm front accessibility is available for service or periodic maintenance.
e) Requested air cooling flow is available.
f) The air conditioning system can provide a sufficient amount of air cooling to keep the room at, or

below, the maximum desired temperature.
g) No dust or corrosive/explosive ga ses are present.
h) The location is vibration free.
i) If the UPS will be installed in bayed enclosures, partition walls have to be installed.

CAUTION: Sealed batteries must never be stored in a discharged or partially discharged state.
Extreme temperature, under-charge, overcharge or over-discharge will destroy batteries!

Key Point: Note the following:

• Charge the battery both before and after storing.

• Always store the batteries in a dry, clean, cool environment in their original packaging.

• If the packaging is removed protect the batteries from dust and humidity.

3.7 UPS Power Cabling (preparation and planning)

3.7.1 General requirements

It is the customer’s responsibility to provide all external fuses, isolators and cables used to connect the UPS
input and output power supplies. The information in this section should assist in the planning and preparation
of the UPS power cabling.

The UPS input supply and bypass supply should be connected to the utility mains through a LV-Distribution
board and protected by a circuit breaker or fuse. This provides overload protection and also a means of
isolating the UPS from the mains supply when required. Similarly, the UPS output supply should be
connected to the load equipment via a suitably fused output distribution panel.

The UPS can be wired with a ‘single feed’ input (standard), whereby the UPS input supply is connected
internally to the UPS bypass circuit (see Figure 3.5); or it can be wired with a ‘dual feed’ input, whereby the
UPS bypass circuit is connected to a dedicated ‘bypass’ supply (see Figure 3.6). These diagrams identify the
UPS input/output cabling requirements and provides information regarding fuse ratings, cable ratings and
cable sizing.

Figure 3.4 outlines of the power terminal connections withing the various UPS cabinets including connection
sizes. Detailed connection diagrams can be found in:

• Figure 3.7 (DPA-25 Input/Output Terminal Block, Front View)

• Figure 3.8 (DPA-75 Input/Output Terminal Block, Front View)

• Figure 3.9 (DPA-125 Input/Output Terminal Block, Front View)

• Figure 3.10 (DPA-50 Input/Output Terminal Block, Front View)

• Figure 3.11 (DPA-150 Input/Output Terminal Block, Front View)

• Figure 3.12 (DPA-250 Input/Output Terminal Block, Front View)

Key Point: This information is given for guidance only. All fuses, isolators and power cables must
be rated and installed in accordance with the prescribed IEC standards or local regulation.

3.10 Connecting the batteries

3.10.1 Safety Notes

1. For personal protection, ensure that the battery cables are connected under the following conditions:
a) No mains voltage is present in the UPS.

b) All the loads are disconnected.
c) The UPS battery isolators are open and the external battery isolators are open in the external battery

cabinet (where used) – i.e. the terminals to which the battery cables are to be fitted are electrically
isolated.

3.10.2 Battery cabling

The UPS battery comprises a number of battery blocks (30-50) connected in series to form a battery string of
the required voltage and capacity; and connected to the UPS module by three connections annotated ‘+’ ‘-’
and ‘N’. The plus and minus connections are taken from the battery string positive and negative extremities
and the ‘N’ terminal is connected to a point mid-way in the battery string (hence the reason why the string
must comprise an even number of battery blocks.

There are two basic battery supply configurations:

• Common battery – where several battery strings are connected in parallel to each UPS module.

• Individual battery – where each module is connected to individual battery string.

These configurations are depicted in Figure 3.13, which shows the alternative connection s for internal
batteries in a 3-module cabinet. Figure 3.14 shows an example of the alternati v e connections when using an
external battery cabinet (shown connected to a 5-module UPS cabinet).

The available battery configurations within the standard internal and external battery cabin ets are described
in paragraph 3.11 (Internal Battery Systems) and paragraph 3.12 (External Battery Cabinets and Battery
Connections).

Figure 3.13 Internal battery connections (3-module UPS cabinet shown)

WARNING: Opening or removing the UPS enclosure covers will create the risk of exposure to

dangerous voltages if power is connected to the UPS.
The final assembly and connection of the battery units must be carried out by (or under the

supervision of) the commissioning engineer. Do not attempt to complete the battery wiring or
close the battery isolators before system commissioning.

3.10.3 Connecting the battery cables

1. Ensure that the UPS input/bypass supply isolators/fuses are open on the input distribution board and
verify that no power is being fed to the UPS.

2. Ensure that the MAINTENANCE BYPASS isolator (IA1) is open (OFF).

3. Ensure that the battery isolators within the UPS cabinet are open.

4. If connecting wiring to an external battery cabinet (or racks):
a) Ensure that the fused battery isolators in the external battery cabinet (or racks) are open.

b) Connect the protective earth cable (PE) between the UPS and external battery cabinet.
c) Connect the battery cables, ensuring the cables are connected to the corresponding + / N /-

terminals.

5. If connecting the internal batteries:
a) Connect the batteries to the battery connection terminal blocks ensuring the cables are connected to

the corresponding + / N /- terminals.

Note: DC and battery fuses are bespoke to the installation.

ON/OFF Start-up and shutdown buttons

The UPS may be switched ON or OFF by simultaneously pressing both ON/OFF keys on the control panel.
This is to prevent accidental UPS start-up or shutdown.

Note: When the UPS is under normal operation, pressing the two ON/OFF simultaneously will immediatel y

shutdown the UPS. In a single module installation this will disconnect the UPS from the load. In a parallel
module system the UPS module will shutdown and the module will effectively be removed from the parallel
load bus; however, the load may or may-not transfer to the bypass supply in the remaining modules
depending on the available module redundancy. To shut down all the modules in a parallel system you must
press both ON/OFF buttons on every UPS cabinet!

LOAD OFF in a PowerWAVE 9000 DPA Single module system

If, for security or emergency reasons, it is necessary to immediately disconnect the load from th e U PS, press
the two red ON/OFF Buttons simultaneously. The simultaneous action of both buttons is necessary to avoid
any accidental manipulation.

LOAD OFF in a PowerWAVE 9000 DPA Parallel module system

If, for security or emergency reasons, it is necessary to immediately disconnect the load from the UPS in a

4: Operation

4.4 Operating Modes

4.4.1 On-Line (Inverter) mode

When the UPS is operating in the On-Line mode the load is supplied th rough the LINE 1 (RECTIFIER) and
INVERTER. This mode provides the highest degree of protection, especially in the event of a mains

disturbance or failure, and is always recommended if the critical loads (comp uter systems) will not tolerate
any (even very brief) interruption of the supply.

In the unlikely event of an inverter fault or overload condition the UPS will transfer the load automatically, and
without interruption, to the static bypass supply (transfer time = 0).

4.4.2 OFF-Line (also known as ECO or Bypass) mode

In the Off-Line (ECO/Bypass) mode the load is supplied from the bypass mains (LINE 2) and the static
BYPASS. In the event of a mains failure the load is automatically transferred to the inverter within 3 to 5 msec

– this is valid for single and parallel module systems. The battery charger remains active in this mode.
Although this mode of operation offers greater efficiency than the On-Line mode, it is recommended only if

the load can tolerate interruptions of 3 to 5 ms – which is the transfer time taken to change from Bypass mode
to On-Line mode.

WARNING: The On-Line mode must always be used to provide maximum load protection.

Figure 4.2 Maintenance Bypass Mode

Each module is fitted with a Maintenance Bypass switch (IA1) which, when closed, connects the UPS module
output terminals directly to the UPS Bypass Mains supply. This facility enables a UPS module to b e shut
down for maintenance or repair whilst maintaining the load on the raw (unprotected) bypass supply.

Maintenance Bypass switch (IA1)

When the UPS is operating on Maintenance bypass the module mimic indications will be as follows

4.4.4 Parallel Isolator switch(IA2)

Each UPS module is provided with an output isolator (IA2). When this isolator is opened it totally disconnects
the UPS module from the output load bus. In a parallel module system this isolates the UPS modules and
allows it to be replaced without having to disturbe the remainder of the system (provided the loss of modules
does not exceed the system redundancy).

WARNING: In a multi-module system ensure that AL L the UPS modules are operating in the
Bypass mode before transferring the load to Maintenance Bypass (IA1)

4.5 Operating Instructions

Under normal operating conditions all the UPS modules in a multi-module system are running, and operating
in the ‘On Line’ (On Inverter) mode.

The following procedures are provided in this section:
How to transfer the load to the Maintenance Bypass and shut down the UPS system for maintenance

purposes – (See paragraph 4.5.1).
How to start up the UPS system and transfer the load from the Maintenance Bypass to the inverters (‘On

Line’ mode) (See paragraph 4.5.2).
How to shut down the entire UPS system (See paragraph 4.5.3).
How to stop/start one module in a redundant multi-module system (See paragraph 4.5.4).

4.5.1 Transfer to Maintenance Bypass Mode

If needed, to perform service or maintenance, it is possible to transfer the load to Maintenance Bypass Mode
and power down the UPS module(s) whilst leaving the load connected to the raw bypass mains supply.

Maintenance

5.1 Introduction

5.2 System calibration

To ensure optimum UPS operation and continuous, efficient protection of the connected load, it is
recommended that the system’s operating parameters are checked every six months and recalibrated where
necessary. The batteries should also be checked every six months, depending on the ambient temperature.

5.3 User responsibilities

There are no user-serviceable parts contained within the UPS so the maintena nce requirements of the user
are minimal. To maximise the useful working life and reliability of the UPS and its batteries, the environment
in which the UPS operates should be kept cool and dust free.

5.4 Routine maintenance

It is essential that the UPS system and batteries receive regular preventative maintenance inspection to
maximise both the useful working life and the reliability of the UPS system. When the UPS is commissioned,
the commissioning field service engineer will attach a service record book to the front of the UPS which will
be used to log the full service history of the UPS.

Preventative maintenance inspections involve working inside the UPS which contains hazardous AC and DC
voltages.

During a preventative maintenance inspectio n the field service engineer will check:

• Site/environment conditions

• Integrity of electrical installation

• Cooling airflow

• Rectifier operation and calibration

• Inverter operation and calibration

• Static switch operation

• Battery status

• Load characteristics

• Integrity of alarm and monitoring systems

• Operation of all installed options

Preventative maintenance inspections form an integral part of all Extended Warranty Agreements
(maintenance contracts) offered by Kohler Uninterruptible Power.

For further details on Extended Warranty Agreements see Paragraph 2.6.

WARNING: All the operations described in this chapter must be performed by authorised
electricians or otherwise qualified personnel.

WARNING: Only Kohler Uninterruptible Powe r trained and authorised field service en gineers
are fully aware of all of the hazardous areas within the UPS.

5: Maintenance

5-2 UPS306-01-00 PowerWAVE 9000 DPA User Manual Dated 01-06-2010

7.3 Generator ON Facilities

The Generator ON facility must use a normally-open contact which closes to indicate that a generator is
running and supplying input power to the UPS.

The UPS Generator port X1/3 and X1/4 is located at the bottom of the DPA Cabinet on the communication
card with terminal blocks X1..X4. See Figure 3.7 for a location drawing.

When used, this facility enables an option to inhibit the operation of the battery charger an d/or static bypass

(See paragraph 4.3.7).

7.4 WAVEMON Shutdown and Management Software

7.4.1 Why is UPS Management important?

By combining a UPS with a variety of network management products, such as orderly shutdown software and
SNMP adaptors, system-administrators can be assured that their electricity supplies are monitored for power
disruptions and depleted battery conditions. Such conditions pose the greatest threat through power
disturbance, to valuable computer data by causing possible corruption or loss. By installing UPS/Mains
monitoring software, administrators are able to monitor the utility power from a central location, allowing early
warning of problems even across more complex systems like Wide Area Networks (WAN) and Enterprise
Wide Networks of multinational companies.

A prolonged mains failure may outlast the battery autonomy of the UPS system. If this situation occurs UPS
management software will initiate an automatic, graceful shutdown of the operating system, protecting
valuable data.

Kohler Uninterruptible Power offer a wide range of local an d remote monitoring and control systems, offering
maximum protection for computer systems.

7.4.2 Wavemon Shutdown and Monitoring Software

Wavemon is an external monitoring and shutdown software which is designed to operate with many of Kohler
Uninterruptible Power UPS products, both with the DRY PORT (Relays) on terminal block X2..X4 and RS232
port JD11 on the communication card.

The software packet consists of a CD ROM for most commonly used operating systems, a standard cable set
and a user manual.

The dry port X2…X4 with voltage-free contacts may also be used for automatic shutdown in connection wi th
WAVEMON Software. It is necessary to provide a cable of 0.5 mm

2

to connect Terminals X2..X4 of the UPS

and the serial port of the server.
The main characteristics of Wavemon software are (assuming RS232 port used):

• Automatic unattended master/slave shutdown in heterogeneous networks.

• On-screen autonomy time/battery time countdown.

• On-screen server log off and shutdown procedure.

• Time and date stamp event log, extensive logging of all UPS activity and power quality data.

• Scheduled UPS economy mode, service mode, other systems status.

• Graphical user interface for Windows compatible platforms.

• Automatic unattended local shutdown.

• Special modules for the MS-Office software to close and save open documents.

• Compatible with all optional modules like UPSDIALER, SNMP adapters, Temperature sensors, etc.

The UPS-Management software is a client-/server-application for networks and l ocal workstations. Basically
WAVEMON-software consists of two parts: the server-module of the UPS-Management Software is
UPSServ, which communicates via RS-232 cable with the UPS.

Working as a background process the UPSServ collects messages, received from the UPS, interprets the
messages and then makes them available to the client-module UPSCli and to any SNMP-based
management station.

When UPSServ detects voltage variations or a power failure it can execute various so called system ‘event
routines’, which for example may shutdown the server or send a warning to connected users. These system
event routines are a part of the UPS-Management Software can be adjusted to suit the customer’s demands.

The UPS management software includes the licence for using the UPS service on one server with one UPS
and an unlimited numbers of connected Windows workstations. When operating wi th two or more servers, a
licence is required for every additional server, irrespective of whether the UPS service runs at that location, or
if the server is halted by a UPS service via remote command.

The same regulations apply to the remote send/receive modules (RCCMD) and multi server shutdown unde r
NT, UNIX and other operating systems. The service programs are generally delivered as a single-licence. To
use a single CD ROM to shutdown multiple servers you have to purchase additional CD license keys.

Parallel/redundant UPS systems are also manageable by the software. The main principle is to introduce a
shutdown of a server only when strictly necessary. Correct parallel han dling has therefore to manage a
parallel system as a whole and always consider the system redundancy.

The following statements apply:

• Every alarm on any unit is immediately notified, but a reaction to a serious fau lt is introduced only

when the minimum number of UPS Modules necessary to supply the load exhibits an alarm situation.

• Battery autonomy time of the parallel system is computed continuously.

• Maintenance on a redundant unit may be executed without affecting the management system

(supervisor).

The PowerWAVE 9000 DPA can be integrated in a network in two ways:

• By means of the server which is being powered by the UPS and is integrated in the network. In most

cases the server is used as a sub-agent and only the Wavemon software is needed, without any
SNMP Adapter. The standard connection is between the RS232 SMART port of UPS and RS232 port
of computer/server.

7-4 UPS306-01-00 PowerWAVE 9000 DPA User Manual Dated 01-06-2010

• If the UPS is powering network hardware such as routers, then an SNMP adapter is necessary. Up to

50 computers can be shut down in a RCCMD (Remote Console Command) environment. RCCMD is
an additional module, which executes a command in a distant system.

7.5 SNMP CARD/ADAPTER For Network Management /Remote Monitoring

The Simple Network Management Protocol (SNMP) is a worldwide-standardized communication-protocol. It
is used to monitor any device in the network via simple control language. T he UPS-Management So ftware
also provides its data in this SNMP format with its internal software agent. The operating system you are
using must be SNMP compatible. We offer our software with SNMP functionality together with NetWare, OS/
2, all Windows NT systems on INTEL and ALPHA.

There are two types of SNMP-Adapters available: External SNMP-Adapter and Internal SNMP-Card (both
have the same functions).

SNMP Adapter

The SNMP adapter requires a PC with terminal connections. For normal operation at le ast one network
connection (Ethernet) is also required.

The SNMP adapter is used to monitor any device in the network and can be used, utilising the RCCMD send
function, for an automatic network wide shut down or informing connected users. The shut down procedure
can be initiate from the remaining time (downtime) or as countd own timer from the beginning of the al arm. A
shut down is therefore possible without extra input from the operator, but fully software controlled.

For detailed information please refer to the Software Manual provided with the WAVEMON CD ROM. This
adaptor communicates via the serial port of the UPS and makes a direct mu ltiple server shut down possible
without additional SNMP management software.

RCCMD - Remote Console Command module for a multi-server shutdown. The RCCMD modules are
independent programs that may be activated on the computer th at is running UPSMAN. This makes a
shutdown call possible in any LAN and WAN, regardless of the network type or operating system.

External SNMP Adapter

The External SNMP adapter is small, 12 x 7 cm. and is supplied with
the following accessories:

• RJ-45 connector for 10/100 Base-T (autoswitchable)

• Serial Port (COM2) or optional ModBus interface.

• Error/Link LED for UPS status

•Aux Port

• DIP Switch

• Serial Port to the UPS (COM1)

• DC Supply (9 VDC or 9-36 VDC supply, depending on

model);
