ELECTRICAL CONNECTIONS

Electrical connection

• An external 24 VDC power supply is necessary to use inputs and outputs. Connect the

common + terminals 19 and 20 to the 24 VDC power supply.

• When switching high current loads, use additional common + terminals to avoid damage to

the base.

• Caution: if the 24 VDC is connected to common "+", the remote unit can be supplied by

the external power supply even if the main power supply is OFF.
