Primary: observe the rules concerning phase and neutral when wiring.
an operating voltage ≥ 600 VAC with a cross-section of 1.5 mm2 (14 AWG) for connection to the mains,
DANGER
ELECTRIC SHOCK
Connect the module grounding terminal to the protective ground, using a green/yellow wire.
Failure to follow these instructions will result in death or serious injury.
The power supply terminal is protected by a flap which allows access to the wiring terminals. The wires come vertically out of the power supply at its base. These wires can be kept in place with a cable-clip.
Secondary: to comply with isolation requirements (EN 60950) for a 24 V SELV isolated voltage, the following wiring is used:
an operating voltage ≥ 300 VAC with a cross-section of 2.5 mm2 (12 AWG) for the 24 V outputs and the ground.
