5.2 Wiring of Power Input Terminal
The power input terminal is a 3-pin screw-󶍾xed pluggable terminal with a pitch of 5.08 mm. To facilitate
wiring, replacement and maintenance, use a spring clamp crimping terminal. The following illustration
shows how the power cable connector is inserted into the power input terminal:

5.3 Wring of I/O Communication Interface
The IO/communication interface is a 12-pin (dual-row) 3.5 mm pitch terminal, which includes UPS
auxiliary signal, RS-232 signal, RS-485 signal, startup signal, PLC program start/stop control signal and
power status signal. Use a screw-󶍾xed spring clamp crimping terminal to facilitate wiring, replacement
and maintenance.
