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.
