Connection Steps:
The input connector board is located on the upper right side of the unit. Please ensure select
the suitable cables according to the table above.
1. Remove the input terminal protective cover from the rear panel of the DC power supply.
2. Scrap off the coating on the power cable tip, the bare portion is approx
mm.

3. Lessen the screw on the green connector.
4. Insert the input cables to the line and ground terminals respectively.
5. Using a suitably sized flat blade screwdriver tighten the screws on the top of terminal bock
assuring the wires are held tightly.
6. Replace the protective cover to avoid electric shock.
7. Sort out the input cables and fix them to the rear panel using a cable tie. The fixture is used
as strain relief. It is also used to prevent the AC plug from loosening and disconnecting due
to vibrations or similar.

Warning!
Connection to the AC input may only be carried out by qualified personnel!
Instruction not to position the equipment so that it is difficult to operate the disconnecting
device.

It is suggested to use an external circuit breaker which protects, and can disconnect all
the current carrying conductors for the AC input cable.

The table below just gives the maximum output current for e ach phase. It is recommend that
keep the input cable as short as possible, because the longer the connection cable, the higher
the voltage loss due to the cable resistance.
Be sure to disconnect the AC mains before accessing the AC input.
The PE conductors is imperative and must always be wired! Otherwise an electric shock
hazard may exist.
Never touch cables or connectors directly after unplugging from mains supply as the danger
of electric shock remains.
Approved flexible cords with double insulation, suitable size, min. 60 deg C. Cable cross
section must be suitable for the maximum input current of the unit as in the following table.
