HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH
Only connect safety extra low voltage (SELV) to relays
on the controller.
Never mix safety extra low voltage (SELV) and other voltages.
Relay circuits to the controller must be protected with
fuse/MCB ≤ 2A.
Failure to follow these instructions will result in death or serious injury.

On the controller 3 potential-free change-over (CO) relays are available. If more relays are needed optional ADBUS cards with 4 additional relays can be used.
NOTE: The terminals for the controller relays are located in the terminal
section at the bottom.
