Connection of the ground to a TSX RKY rack

Grounding racks

Functional grounding of the racks is provided by the back, which is made of metal.

This means that the PLCs will be guaranteed to conform to environmental norms; assuming, however, that the racks are fixed to a metal support that is correctly connected to ground. The different racks which can make up a TSX P57/TSX H57 PLC station must be mounted either on the same support or on different supports, as long as the latter are correctly interlinked.

DANGER

ELECTRIC SHOCK - IMPROPER GROUNDING

Each rack’s grounding terminal must be linked to the protective ground.
Use a green/yellow wire with a minimum section of 2.5 mm (12 AWG) and with the shortest length possible.
Maximum torque on the ground connection screw: 2.0 N.m (1.5 lb-ft).
Install to confrom to all local and national codes.

Failure to follow these instructions will result in death or serious injury.

NOTE: The PLC’s internal 0V is linked to the ground connection. The ground connection itself being linked to ground.
