of the control box.
D. Remove plastic cap on the right side of control box and
install suitable conduit fitting in enclosure.

authorized method (wire nuts, etc).

grounded in accordance with the National Electric Code
ANSI/NFPA70 and/or local codes. These must be followed

permanent wiring system; or an equipment grounding
conductor must be run with the circuit conductors and
