Install the Controller into the Chassis
1. Insert the key into the 1756-L6
xS controller.
2. Turn the key to the PROG position.
The 1756-LSP safety partner does not have a keyswitch.
3. Align the circuit board with the top and
bottom guides in the chassis.
4. Slide the controller into the chassis.
The controller is fully installed when it is
flush with the power supply or other
installed modules and the top and
bottom latches are engaged.
WARNING
When you insert or remove the module while backplane 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.
Repeated electrical arcing causes excessive wear to contacts on both the
module and its mating connector. Worn contact may create electrical
resistance that can affect module operation.
IMPORTANT
You must install the 1756-LSP safety partner in the slot immediately to
the right of the 1756-L6xS controller. Follow steps 3 and 4 above to
install the 1756-LSP safety partner.
