If a grounding strip is available at the installation site, connect the grounding cable to the grounding strip.
Procedure
1. Attach the two-hole grounding lug at one end of the grounding cable to a grounding point on the switch chassis. (See
Connecting the grounding cable on page 19.)
2. Remove the hex nut of a grounding post on the grounding strip.
3. Attach the ring terminal at the other end of the grounding cable to a grounding post on the grounding strip, and fasten the
ring terminal with the removed hex nut.
