conduit has to be connected to the middle
post of the main terminal block. The
remaining two wires of the power cord or
conduit have to be connected to the outside
posts of the main terminal connection block.
Failure to do so can result in electrical shock,
severe personal injury or death.
Install the power cord as follows:
For power cord installations, hook the strain relief
over the power cord hole (1
