Connecting the Alarm Relay

All Sunways Solar Inverters are equipped with a potential-free alarm relay. The relay is designed as a make-contact element and is always triggered when the device reports an error. That ensures that any faults in the PV system are reported quickly and reliably on site. With PV systems with several Solar Inverters, the individual relays can be paralleled and connected via a joint indicator light.

The alarm relay cannot be triggered if there is a power failure on L1, because that is the supply phase for the Solar Inverter.

The alarm relay cannot be triggered if there is a grid failure on L1 since this is the supply phase for the solar inverter.

· Connection

Move the cover of the Solar Inverter up, and fix it in position by tightening a lateral screw. See chapter 2.1 «Safety Instructions».

The required terminal block with the connections «S-» and «S+» is on the lower right side of the circuit board («X5»). Allocate the terminals as shown:

· Important Information:

￿!

The alarm relay is rated for 230 V / 2 A. Any higher power/voltage may destroy the relay. The connected indicator module must be fused separately!

·Connecting a cable to the spring-loaded terminal

·Use a small screwdriver. Press the orange terminal. The terminal will open.

·Insert the (at least 11 mm bare) cable into the respective terminal hole.

·Release the pressure from the screwdri- ver. The cable is now attached to the connection.

·Make sure the cable is connected tightly.
