5.10 Dry Contact Connection
Dry contact cables require a cross section of 18AWG~16AWG.
The connection procedure of the dry contact is the same as that of the RS485
terminal block.
5.10.1 Dry Contact Function
The configuration circuit board is provided with fault output dry contact and emergency
shutdown dry contact, as shown in the Figure below.
Connection method of the dry contacts is similar to that of the RS485 terminal block.

user can configure it to be a normally open contact (COM ＆ NO) or a normally closed
contact (COM＆NC).
The relay is initially at the NC terminal, and it will trip to another contact when a fault
occurs.When alarm occurs, signal status change will be not be triggered..
Use LED indicators or other equipment to indicate whether the inverter is in the faulty
state. The following Figures show the typical applications of normal open contact and
normaliy closed contact:
