Wiring
Before connecting or disconnecting any wires, ensure that all power supplies have been switched off and all
wires are potential-free to prevent equipment damage and avoid electrical shock.
Do not run wiring close to transformers or high frequency generating equipment. Complete and verify all
wiring connections before applying power to the controller to which the module is connected.
