CAUTION:
• Connect the grounding cable to the grounding strip in the equipment room. Do not connect it to a
fire main or lightning rod.
• To guarantee the grounding effect and avoid switch damage, use the grounding cable provided
with the switch to connect the switch to a grounding strip in the equipment room.
If a grounding strip is available at the installation site, use the grounding cable provided with the
