Connecting Inputs and Outputs

D000029326 en g – E450 PLC 1-phase ZCX100Px – User Manual
Avoid any contact of input and output wires with mains terminals
The inputs and outputs are usually insulated circuits or extra-low voltage
circuits. Avoid any contact of input and output wires with phase connection
terminals by proper arrangement of the wires under the terminal cover.
Make sure that the input and output wires are not squeezed or damaged in
the vicinity of the phase connection terminals.
Connect the respective wires to the S0-input, the relay outputs and the M-
Bus interface (if required).

Relay outputs require overcurrent protection
The relay outputs 1 and 2 must be protected against overcurrent by exter-
nal fuses. Overcurrent will damage the relay!
Relay output 1: 250 VAC/90 mA or optional 5 A maximum current
