Step 4. Remove the terminal block cover on the rear panel of UPS. Then connect the wires according to the following terminal
block diagrams: (Connect the earth wire first when making wire connection. Disconnect the earth wire last when making wire
disconnection!).
Note 1: Make sure that the wires are connected tightly with the terminals.
Note 2: There are two kinds of outputs: output terminal/outlets and programmable terminal. Please connect non-critical
devices to the programmable terminal and critical devices to the output terminal/outlets. During power failure, you
may extend the backup time to critical devices by setting shorter backup time for non-critical devices.
Note 3: Please install the output breaker between the output terminal and the load, and the breaker should be qualified
with leakage current protective function if necessary.
Step 5. Insert the EPO plug into the EPO slot on the rear panel.
Step 6. Put the terminal block cover back to the rear panel of the UPS.
WARNINGS:
• 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!
• 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!
• 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 quantity 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.
