Warning
When installing this equipment, always ensure that the power supply
ground connection is installed first and disconnected last.

Only one grounding post on the switch should be connected to the
building protective earth. The second grounding post should not be

power supply 1 (PSU 1).
1. Strip an adequate amount of insulation from one end of the ground
cable, for the ring lug. The amount may vary depending on the type of
ring lug, but 6.5mm (0.25 in) is typically sufficient. Refer to Figure 34.
