1 Introduction

1.1 Scope of the Manual

This instruction manual explains the installation, interconnection, and operation of Argus Technologies’ INEX

Inverter System.

1.2 Product Overview

INEX inverter series is an integrated telecommunication AC power system, including inverter, static switch, LCD

controller, and interface modules. With versatile “building block” design and N+1 redundant configuration, INEX

inverter system facilitates complex telecommunication and industrial power demands.

INEX series DC to AC inverter module is available for 1000VA (800W) or 1500VA (1200W) to convert -48Vdc

input to 120Vac or 230Vac output at 50Hz or 60Hz. The inverter module is “hot swappable” meaning it can be

inserted or removed from the shelf without cutting power to or from the system.

A universal 19” shelf is designed to parallel connect and synchronize all INEX inverter models. With this shelf,

INEX series employs N+1 redundant configuration to output power maximum of 12kVA for 120Vac models and

18kVA for 230Vac models, and to operate in N+1 redundant mode for optimization. INEX “all master” dynamic

mechanisms automatically share and re-organize critical loads to further prevent interruption if one or more

inverter modules fail.

INEX selective static transfer switch (STS) provides automatic instantaneous load transfer, which further secures

uninterrupted operation of sensitive electronic equipment.

The INEX system controller, equipped with a DSP microprocessor, gives real-time system status through

comprehensive LCD/LED indication, and allows program settings through the display panel. A communication

interface module provides local or remote control and monitoring of the system.

• Comprehensive LCD/LED display provides system status, and user-friendly panel eases program settings.

1.2.1 WinPower Software

WinPower is a power management software specifically designed to monitor and control the INEX inverter system

via a personal computer. It is available to download via the Argus website (www.argusdcpower.com).

To remotely monitor and control INEX inverters, connect the USB cable (A-B type) to the port on the front panel of

the interface module. Then follow instructions stated in the WinPower manual to properly install the software to a

personal computer physically connected to the INEX inverter system.

2 Inspection

2.1 Packing Materials

All Argus products are shipped in rugged, double walled boxes and suspended via solid inserts to minimize shock

that may occur during transportation. Packaging assemblies and methods are tested to International Safe Transit

Association standards.

Power systems are also packaged with Cortex. This plastic wrap contains a corrosive-inhibitor that protects the

product from corrosion for up to two years.

2.1.1 Returns for Service

Save the original shipping container. If the product needs to be returned for service, it should be packaged in its

original shipping container. If the original container is unavailable, make sure the product is packed with at least

three inches of shock-absorbing material to prevent shipping damage.

NOTE: Argus Technologies is not responsible for damage caused by the improper packaging of returned products.

2.2 Check for Damage

Prior to unpacking the product, note any damage to the shipping container. Unpack the product and inspect the

exterior for damage. If any damage is observed contact the carrier immediately.

Continue the inspection for any internal damage. In the unlikely event of internal damage, please inform the

carrier and contact Argus Technologies for advice on the impact of any damage.

Verify that you have all the necessary parts per your order for proper assembly.

3 Shelf Installation

This chapter is provided for qualified personnel to install the product.

3.1 Inverter Shelf Preparation/Mounting

The inverter shelf has been designed for flush or mid-mounting in a 19” relay rack. Mounting brackets are also

supplied for mounting in a 23” rack.

NOTE: The shelf shall be mounted in a clean and dry environment. Allow at least 1.75” of free space in front of the unit

for unrestricted cooling airflow.

1. There are four holes right above three deck connectors of each inverter slot. Based on inverter model, insert

the supplied nylon guide pin to the corresponding hole:

• Position A for INV-4815A (as shown below)

• Position B for INV-4815EA

• Position C for INV-4810A

• Position D for INV-4810EA

CAUTION

System will fail to operate normally when inverter modules of different specifications are inserted

into inverter shelves. Use supplied nylon guide pins for securing only inverter modules of the

same specifications.

Nylon guide pins shown in Position A

Argus Technologies Ltd. 014-114-C0 Rev D WC

2. The shelf should be mounted to the rack using at least two

#12 – 24 x 1/2” screws in each bracket. Philips-type screws

and screwdriver should be used to eliminate the possibility of

slippage and scratching of the unit’s exterior. Washers (such

as internal tooth) or special screws that are designed to cut

through the painted surface should be used to ensure a good

chassis ground.

3. Put the inverter shelf into the equipment rack horizontally,

and align holes of mounting brackets and rack.

4. Each inverter shelf holds maximum two inverter modules.

Repeat the steps above to install the inverter shelves as

required.

5. All input and output connections are made through the knockouts, located in the top

and the bottom of the shelf rear cover, as well as both side panels.

Remove the rear cover to access the inverter shelf backplane and connectors.

6. Knockouts on top and bottom are for shelf inter-connections and supplementary wire

routing. To remove knockout, snip tabs, move plate up and down until tabs in back

snap apart.

3.2 Controller/Interface/STS Shelf Mounting/Preparation

The shelf has been designed for flush or mid-mounting in a 19” relay rack. Mounting brackets are also supplied

for mounting in a 23” rack.

NOTE: The shelf shall be mounted in a clean and dry environment. Allow at least 1.75” of free space in front of the unit

for unrestricted cooling airflow.

1. The shelf should be mounted to the rack using at least two #12

– 24 x 1/2” screws in each bracket. Philips-type screws and

screwdriver should be used to eliminate the possibility of

slippage and scratching of the unit’s exterior. Washers (such as

internal tooth) or special screws that are designed to cut

through the painted surface should be used to ensure a good

chassis ground.

2. Put the shelf into the equipment rack horizontally, and align

holes of mounting brackets and rack.

NOTE: Each INEX controller module or interface module allows maximum

control of 12 inverter units cascaded. It is recommended to have the

controller/interface/STS shelf installed on top of stacked inverter

shelves to ease inter-connections; however, it may be installed

below the inverter shelves if the MBSDU panel is not required.

All input and output connections are made through the knockouts, located in the top and the bottom of each of the

two rear covers, as well as both side panels. The cover on the right is for the controller/interface section, and the

cover on the left is for the STS section.

3. Remove the rear cover(s) to access the shelf backplane and

connectors.

4. Knockouts on top and bottom are for shelf inter-connections. To

remove knockout, snip tabs, move plate up and down until tabs

in back snap apart.

3.3 MBSDU Panel Mounting/Preparation

The panel has been designed for flush or mid-mounting in a 19” relay rack. Mounting brackets are also supplied

for mounting in a 23” rack.

NOTE: The panel shall be mounted in a clean and dry environment.

1. The panel should be mounted to the rack using at least two #12

– 24 x 1/2” screws in each bracket. Philips-type screws and

screwdriver should be used to eliminate the possibility of

slippage and scratching of the unit’s exterior. Washers (such as

internal tooth) or special screws that are designed to cut through

the painted surface should be used to ensure a good chassis

ground.

2. Put the panel into the equipment rack horizontally, and align

holes of mounting brackets and rack. The panel must be

mounted above the controller/interface/STS shelf.

3. All input and output connections are made through the knockouts, located in the bottom of the rear cover and

both side panels. To remove knockout, snip tabs, move plate up and down until tabs in back snap apart.

4. Remove the rear cover to access the backplane and connectors.
