4 Hardware IO connection
This chapter gives more details on how to use the I/O s of the controller compared
to the datasheet.
4.1 Power data
Power supply
DC 24 V, G0 (T7)
Operating voltage DC 24 V ±10%
Max. power consumption 35 W
Max. external supply line fusing 3 A slow wire fuse or circuit breaker
Notes:
● Ground the controller for safety reasons and to reduce EMC disturbances.
● Follow the regulations on grounding. Connect terminal G0 directly to protective
earthing (PE).
● Install a fuse as specified in the data sheet. When connecting to I/O extension
modules, set the fuse separately for the I/O as per the specifications.
Refer to the Climatix EMC design guideline (CE1Q3993en) for more details on
panel design.
