Connecting Procedures:

1. Tighten the lock screws on positive and negative connector.
2. Strip the insulation of the positive and negative cables with 8-10mm 

length.

The inverter is integrated with alarm output dry contact and emergency 
stop dry contact.
Alarm output dry contact:
Relay can be set to normal open contact (COM&NO) or normal close con

-

tact (COM&NC), when inverter is in alarm/fault state, the fault status can 
be indicated by LED indicator or other external display device.

them tightly with a wire crimper. Make sure that the withdrawal force of 
the pressed cable is bigger than 400N. 

5. Plug in the pressed positive and negative cables into relevant insulated 
enclosure, a “click” should be heard or felt when the contact cable assem

3.Feed the positive and negative cables into corresponding lock screws.

7.Make sure the DC switch is at OFF position
8.Connect the positive and negative connectors into positive and negative 
DC input terminals of the inverter, a “click” should be heard or felt when 

the contact cable assembly is seated correctly.
