FSP Proline 3/1 20K — инструкции по установке и подключению источников бесперебойного питания [14/48]

Warning: (Only for standard model)

● Make sure the UPS is not turned on before installation. The UPS should not be turned on during wiring

connection.

● Do not try to modify the standard model to the long-run model. Particularly, do not try to connect the

standard internal battery to the external battery. The battery type and voltage may be different. If you

connect them together, it maybe causes the hazard of electric shock or fire!

Warning: (Only for long-run model)

● Make sure a DC breaker or other protection device between UPS and external battery pack is installed. If

not, please install it carefully. Switch off the battery breaker before installation.

NOTE: Set the battery pack breaker in “OFF” position and then install the battery pack.

● Pay highly attention to the rated battery voltage marked on the rear panel. If you want to change the

numbers of the battery pack, please make sure you modify the setting simultaneously. The connection

with wrong battery voltage may cause permanent damage of the UPS. Make sure the voltage of the

battery pack is correct.

● Pay highly attention to the polarity marking on external battery terminal block, and make sure the

correct battery polarity is connected. Wrong connection may cause permanent damage of the UPS.

● Make sure the protective earth ground wiring is correct. The wire current spec, color, position,

connection and conductance reliability should be checked carefully.

● Make sure the utility input & output wiring is correct. The wire current spec, color, position, connection

and conductance reliability should be checked carefully. Make sure the L/N site is correct, not reverse

and short-circuited.

● Before turning on the UPS, be sure the breaker of the battery pack is on.

● UPS will alert while the external battery breaker is not on. If so, turn on the external battery breaker and

press “test” button on the UPS to release the audible alert.

2-4. UPS Installation for Parallel System

If the UPS is only available for single operation, you may skip this section to the next.

1) Install and wires the UPSs according to the section 2-3.

2) Connect the output wires of each UPS to an output breaker.

3) Connect all output breakers to a major output breaker. Then this major output breaker will directly

connect to the loads.

4) Each UPS is connected to an independent battery pack.

NOTE: The parallel system can not use one battery pack. Otherwise, it will cause system permanent failure.

5) Refer to the following wiring diagram:
