When attaching the controller, power supply, and I/O
modules, make sure the bus connectors are securely locked
together to ensure proper electrical connection.
If you connect or disconnect 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.
During panel or DIN rail mounting of all devices, be sure that
all debris (metal chips, wire strands, etc.) is kept from falling
into the controller. Debris that falls into the controller could
cause damage while the controller is energized.
