Installation of an MES120 module on the base unitb insert the 2 pins on the MES module into the slots 1 on the base unitb flatten the module up against the base unit to plug it into the connector H2b partially tighten the two mounting screws 2 before locking them.

MES120 modules must be mounted in the following order:b if only one module is required, connect it to connector H1b if 2 modules are required, connect them to connectors H1 and H2b if 3 modules are required (maximum configuration), the 3 connectors H1, H2 and H3 are used.

For safety reasons (access to dangerous voltages), all terminals must be screwed tight, whether or not they are used.The inputs are potential-free and the DC power supply source is external.

Wiring of connectorsb wiring without fitting:v 1 wire with maximum cross-section 0.2 to 2.5 mm² (u AWG 24-12) or 2 wires with maximum cross-section 0.2 to 1 mm² (u AWG 24-16)v stripped length: 8 to 10 mmb wiring with fittings:v recommended wiring with Telemecanique fitting:- DZ5CE015D for one 1.5 mm² wire- DZ5CE025D for one 2.5 mm² wire- AZ5DE010D for two 1 mm² wiresv tube length: 8.2 mmv stripped length: 8 mm.
