ATTENTION
!
Be careful when stripping wires. Wire fragments that fall into the
controller could cause damage. Once wiring is complete, be sure
the base unit is free of all metal fragments before removing
protective debris strips and installing the processor unit. Failure
to remove strips before operating can cause overheating.
ATTENTION
!
Before you install and wire any device, disconnect power to the
controller system.
