WARNING:
Before connecting any wires, make sure the AC input and battery power is completely shut off.
Make sure that the breakers, input1 breaker (Q1), input2 breaker (Q2 for dual input model), output
breaker (Q3 for 160K/200K models), maintenance breaker (Q4 for 160K/200K models), and battery
breaker are all in the “OFF” position.
Make sure the maintenance bypass switch is in “UPS” position (only for 100K/120K models).
5)
Remove the terminal block cover on the rear panel of UPS. Then, connect the input1, input2 (only
available for dual input model), output and battery wires according to the function indicated on terminal
block. (Connect the grounding/earthing wire first when making wire connection. Disconnect the
grounding/earthing wire last when making wire disconnection!)
NOTE 1: Make sure that the wires are connected securely with the terminals.
NOTE 2: Please install the output breaker between the output terminal and the load. This breaker must
have leakage current protective function.
6)
Put the terminal block cover back to the rear panel of the UPS.
Warning:
● Make sure the UPS is not turned on before installation. The UPS
should not be turned on during wiring
connection.
Warning:
● Make sure a DC breaker or other protection device between UPS and external battery pack is installed.
Switch off the battery breaker before installation.
NOTE: Set the battery pack breaker to “OFF” position and then install the battery pack.
● Pay
special attention to the rated battery voltage marked on the label. If you want to change the
numbers of the battery pack, please make sure you modify the setting accordingly. The connection with
wrong battery voltage may cause permanent damage to the UPS.
● Make sure the protective
grounding/earthing wiring is correct. The current spec, color, position,
connection and conductance reliability of the wires needed be checked carefully.
