Chapter 2 Switch Installation
Remove the Switch from the DIN Rail
To remove the switch from a DIN rail or a rack, follow these steps.
1. Remove power from the switch, and disconnect all cables and connectors
from the front panel of the switch.
2. Insert a tool, such as a flat-head screwdriver, in the slot at the bottom of the
spring-loaded latch and use it to release the latch from the DIN rail.
Ground the Switch
For DC power connections, use UL- and CSA-rated, style 1007 or 1569
twisted-pair copper appliance wiring material (AWM) wire.
WARNING: If you connect or disconnect power or alarm wiring while the
field-side power is on, an electrical arc can occur. This could cause an explosion
in hazardous location installations. Be sure that power is removed or the area is
nonhazardous before proceeding.
ATTENTION: This equipment must be grounded. Never defeat the ground
conductor or operate the equipment in the absence of a suitably installed
ground conductor. Contact the appropriate electrical inspection authority or an
electrician if you are uncertain that suitable grounding is available.
This equipment is intended to be grounded to comply with emission and immunity
requirements. Make sure that the switch functional ground lug is connected to
earth ground during normal use.
ATTENTION: To make sure that the equipment is reliably connected to earth
ground, follow the grounding procedure instructions and use a suitable ring
terminal lug, such as Thomas & Betts part number 10RCR or equivalent.
