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.
