4.
Plug one wire into each of the "BatCur" contacts of the 4-pole terminal included.
5.
Tighten the screws of the contact.

7.6.3 Multi-function Relays 1 and 2
The Sunny Island offers you several options for the control of internal and external processes. To this
end, the device is equipped with two multi-function relays to which you can assign functions with the
parameters "241.01 Rly1Op" and "241.02 Rly2Op" (see chapter 14 "Relay" (Page 152)).
Commissioning the Battery Temperature Sensor
When connecting the battery temperature sensor, set up the internal offset on the Sunny
Island during the first commissioning of the island grid system (see chapter 9.3
"Commissioning the Battery Current Sensor" (Page 81)).
DANGER!
Death hazard due to faulty insulation
Separate the relay cable safely away from the communication area.
•
Strip the wires of the relay cable.
•
Fit each individual wire with the silicon tube included in the delivery.
•
The device should not be operated without the silicon tube.
Information
The slave devices' relays can also be used and programmed separately.
Information on the switching capacity of the relays is provided in section 20 "Technical
Data" (Page 197).
