Connecting the digital outputs
14. Connecting the digital outputs
These units are provided with two volt-free contacts, whereby each contact is rated from 6 A to 250 VAC. Both
digital outputs can be configured for different uses using the display.
This chapter explains the requirements and process for connecting the digital output wiring to the unit. Read
carefully before starting the connection process.
14.1. Safety instructions for connecting the digital outputs
Before you start to make the connections, make sure there is no voltage in the inverter. Check that
the AC protection of the auxiliary grid/genset and the DC switch are open.
Do not switch on the power to the unit until you have successfully made the rest of the connections
and the unit is closed.
14.2. Wiring requirements for connecting the digital outputs
The wiring gauge for connecting the digital outputs is specified in the following table:
Temperature sensor wiring gauge
Cable diameter
14.3. Connection process of the digital outputs
To connect the digital outputs:
1.
Loosen the corresponding packing gland (see Section "2.7. Description of wiring inlets"), remove the cap
and pass the cable through it.
2.
Connect the cable to terminals J36 EXT. 1 RELAY and J44 EXT. 2 RELAY as shown in the previous
figure. In the case of using one single digital output, only make the connection to terminal J36 EXT. 1 RELAY.
Ingeteam recommends using a tubular terminal in accordance with DIN 46 228/1.
3.
Correctly tighten the packing glands to prevent losses to the protection class, verifying that the wiring is
not taut. Check that the connection is tight.
