4.2 DELIVERY

When delivered, check carefully the package integrity and the physical conditions of the UPS equipment.

In case of any damage sustained during transport, immediately inform the carrier and contact your local Service Center.

A detailed report of the damage is necessary for any insurance claim.

NOTE !

A damaged UPS must never be installed or connected to utility or battery!

4.3 STORAGE

The equipment is carefully packed for transport and storage so that it is in a perfect condition when eventually installed.

Never leave a UPS outside the building and do not store the UPS one on top of the other.

It is recommended to store the UPS in its original package in a

dry, dust free room and far away from chemical substances, with temperature not exceeding -13°F to 131°F (-25°C to 55°C).

4.3.1 Storage of the UPS

Some important functions of the UPS, such as the customized functions, are defined by parameters stored in a RAM memory. The RAM is supplied by a small backup battery located on the Control Unit board.

If the storage time of the UPS exceeds 1 year, these functions should be verified by an authorized Service Center before putting the UPS into operation.

NOTE !

In case of storage of the UPS pay attention to:

4.3.2 Storage of the battery

In case of extended storage, when the delivery includes maintenance free batteries, keep in mind that they are subject to auto-discharging process

To avoid permanent damages to the battery, you must observe the following instructions:

 The storage time without charging the battery depends on the ambient temperature of the storage area.  The optimal ambient temperature for the batteries is 68°F (20°C).

For storage temperature higher than 68°F (20°C), the storage time will decrease.

 Each additional 18°F (10°C) over the nominal temperature of 68°F (20°C) will decrease the storage

time, without freshening charge, by half.

In case of a maintenance free battery, the storage time without charging the battery is approximately:

6 months with storage temperature 68°F (20°C) 3 months with storage temperature 86°F (30°C) 2 months with storage temperature 95°F (35°C)

NOTE !

In case of battery storage pay attention to:

4.4 PLACE OF INSTALLATION

The UPS should be installed in a restricted area where only qualified personnel should be admitted.

The place of installation should be clean, dust-free, and provided with proper ventilation or air- conditioning.

Verify for sufficient floor load capacity (see Section 4.1.1).

We strongly advice that the ambient temperature should not exceed 68° - 77°F / 20° - 25°C (max. 104°F / 40°C). See Section 4.5.

Positioning of the UPS LP33 Series 20 & 30

Fig. 4.4-1 Positioning LP33 Series 20 & 30

The rear panel of the UPS may be mounted flush to a wall or other structure.

Clearance around the front of the unit should be sufficient to enable free passage of personnel with the doors fully open, and to allow sufficient airflow to the door vents.

To guarantee proper cooling air exhaust, the recommended minimum clearance between ceiling and top of the UPS is 16” (400mm).

Battery cabinets must be placed beside the left side of the UPS cabinet.

A single-phase power outlet (208Vac) should be provided near the UPS for connection of power tools, test equipment or connectivity devices. This outlet must be grounded.

The LP33 Series 20 & 30 UPS can radiate radio frequency energy. Although some RFI (Radio Frequency Interference) filtering is inherent to the UPS there is no guarantee that the UPS will not influence sensitive devices such as cameras and monitors that are positioned close by. If interference is expected, the UPS should be moved away from the sensitive equipment.

NOTE !

Operating temperature is very important for valve regulated battery (maintenance free).

Operation at temperatures higher than 68°F (20°C) will reduce life expectancy. Follow the recommendations of the battery supplier and other local standards. The installation and cabling of the battery must be done by qualified people.

4.7 ELECTRICAL WIRING

WARNING !

UPS installation and connection must be performed by QUALIFIED SERVICE PERSONNEL only.

It is the responsibility of the installation technician to ensure that all local and national electric codes are adhered to.

4.7.1 Utility input connection

WARNING !

Ensure that the AC and DC external isolators are OFF and locked out to prevent their inadvertent operation.

Do not apply power to the equipment prior to the commissioning by a QUALIFIED SERVICE ENGINEER.

Before any other input connection, connect and check the grounding wire.

The UPS has availability of input terminations for the Rectifier and Bypass. The unit may be powered from a common input source or dual input sources (option).

Common input Rectifier & Bypass

Fig. 4.7.1-1 Common Input Rectifier & Bypass

The same power source is to be used for both Bypass Supply and Rectifier Input (input F1).

Bear in mind that when the Utility Fuses are opened there is a supply failure to the Rectifier as well as to the Bypass and Manual Bypass.

Dual input Rectifier & Bypass (option)

Fig. 4.7.1-2 Dual Input Rectifier & Bypass (option)

The Bypass and Rectifier inputs are to be powered from different Utility supplies (F2 and F3 inputs).

In this case, when the Rectifier

Input Fuses are opened, the Bypass and the Manual Bypass

are supplied by the other source.

4.7.2 Input/output over current protection and wire sizing

The cabling of the UPS system has to be sized according to the UPS power rating. Sizing of circuit breakers, fuses and cables for Input Utility, Output Load and Battery must meet the requirements of local and national electrical codes.

Before connecting the UPS, verify that the Utility Voltage and Frequency, the Output Load Voltage and Frequency and Battery Data (cells number, floating voltage, autonomy) are according to the required specifications.

Output load configuration may be such that one phase may carry a load current at 100% of that phase’s maximum current rating while the other two phases run at 0% or any combination in between. Ensure that the load does not consist of any equipment that may require high starting currents such as electric motors, laser printers, etc. This may cause the UPS to occasionally go into Bypass due to overload conditions

To choose the correct input fuses or circuit breaker, consider the available short-circuit current of the system up-stream. Choose the correct fuse or breaker using current data shown in the chart and the appropriate NEC code.

The ratings indicated in the following chart do not consider any line voltage drop.

In case of optional input transformer the input protective devices should be sized to allow the transformer magnetization inrush current.

Caution when using four-pole circuit breakers as protection. A potential problem exists for situations with non-linear loads:

The neutral current could be greater than the phase currents.

The three-phase Utility power supply must be symmetrical with respect to ground, due to the existence of voltage surge protection devices inside the UPS.

NOTE !

If you use ELCB breaker (Earth Limiting Circuit Breaker) to protect the input connections, consider the high leakage current generated by the noise suppression capacitors. If these ELCB breakers are strictly necessary, we suggest using the largest type suitable for non-linear current and for delayed operations.

To ensure coordination when the UPS is configured for Separate Bypass and Rectifier Inputs, special care must be taken in choosing the fuse or circuit breaker ratings installed in the output distribution circuits. Protective devices on the output of the UPS should be coordinated with the Bypass Input circuit protection. Due to the relatively low short circuit capability of the UPS inverter, a short circuit in the load will cause an immediate transfer to Bypass.

The largest fuse or circuit breaker in the output distribution should be rated at no more than 60% of the rating of the protective device supplying the Bypass line.

If circuit selectivity is required while the load is fed from the inverter (Bypass Utility not available), the largest fuse or circuit breaker should be rated at no more than 20% of the UPS output current rating.

Fig. 4.7.2-1 RPA Parallel System

In order to ensure a correct load sharing between the parallel units, when the load is supplied by utility, it is recommended to keep the cable size and length from the input distribution board to the output bus-bar the same for each parallel unit.

Utility Bypass input voltage must be the same for all units, thus avoiding phase shift or phase rotation problems.

To avoid mutual induction effect, the input cables must be run in separate conduit from the output cables.

NOTE !

No transformers, fuses or automatic circuit breakers should be inserted between the unit’s output and the load common bus-bars.

The delivery and installation of fuses and input / output connections of the UPS are at the customer’s expense, unless agreed otherwise.

NOTE !

It is recommended to provide an additional length of the input/output cables so that the UPS can be moved for maintenance purpose.

It is recommended to use flexible input/output conductors with suitable length to admit a sufficient displacement.

4.7.3 Battery over current protection and wire sizing

 Please read the safety precautions at the front of this guide carefully, and thoroughly review the

battery manufacturer’s installation and maintenance manual before connecting the batteries to

the UPS.

 Choose an appropriate DC fuse or circuit breaker using the current data in the chart below.  Minimum battery cable requirement is based on the current data below.

4.9.5 UPS functioning as frequency converter

NOTE !

The set-up for LP33 Series 20 & 30 when functioning as frequency converter requires a particular installation and adequate setting of some parameters (accessible

only through password), and can therefore only be done by a GE QUALIFIED

SERVICE ENGINEER.

The LP33 Series 20 & 30 can run as frequency converter only with a connected battery, as a standard UPS.

When the UPS LP33 Series 20 & 30 is delivered as frequency converter (different output frequency with respect to the input frequency), the automatic bypass and manual bypass functions are disabled.

Therefore the load cannot be transferred to mains in case of overload, short circuit, or inverter failure.

In cases where the UPS needs to be powered down for maintenance purposes, the critical load must also be powered down during this time.

When the set-up parameters of the UPS are set for frequency converter, the ECO Mode operation is automatically disabled.

The UPS delivered as frequency converter has the following differences:

 Automatic bypass disabled by setting of dedicated parameter (access protected by password

reserved to service engineer).

 The handle of the switch Q2 - manual bypass is removed to avoid accidental wrong manipulations.  Mains bypass disabled by removing the fuse F3 fitted on the board P2 – Power Supply.

WARNING !

In case a UPS delivered as frequency converter should be set on site for UPS standard version, the operation must be performed by a QUALIFIED SERVICE ENGINEER.

Notices for installation:

 For UPS with common AC input follow the standard procedure described in Section 4.9.1.

Notices for start-up procedures:

 Follow the standard procedure indicated in User Manual.

Notices for shut-down procedures:

 Follow the standard procedure indicated in User Manual.

NOTE !

The inverter can be turned off only by pressing the “Load Off” key.

No function

Inverter On

Inverter OFF

Generator ON

Print all

Status relay

External bypass ON

External battery fuses

Voltage free contacts:

Max. DC / AC: 24V / 1.25A IEC 60950 (SELV circuit) Min. signal level: 5VDC / 5mA

Gen Set signaling

If an Emergency generator set supplies the UPS in case of utility failure and the generator is particularly unstable in frequency, it should be suitable to install the signal “generator on” on terminals X1 / 11, 22 (Normally Open voltage-free contact) or on connector J2 / 11, 24 (see Fig. 5.4-1 / X1 and J2). Since the Parameter for of the reading of the Generator function is password protected, call the nearest Service Center for it's activation.

When this contact closes, it causes the change of certain settable functions such as:

 Enabling or disabling of synchronization and consequently the load transfer to generator.  The battery recharge inhibition during the generator operation, or after what delay from generator

start the battery will start to be recharged.

Consult your nearest Service Center at +1-800-637-1738, or by E-mail at pqservice@ge.com for more information.
