CONNECT THE MAIN POWER SUPPLY
WARNING! Turn the main power off before you
make any electrical connections or set any switches
inside the control panel box.
Wire the main power supply to control panel terminals
in block J1 (see Figures 8 and 9). The installer is
responsible for insuring that a separate, grounded
circuit protected by a circuit breaker is between the
control panel and the main power supply. All wiring
should conform to applicable electrical codes, and all
wiring and fittings should be weatherproof and/or
suitable for burial.
Connect the ground to the grounding terminal in block
J1 and connect the power wires to the terminals labeled
N (neutral) and L (phase).
CAUTION: The operators are grounded only by
the grounded circuit the installer provides.
N
OTE: For a 230V system, a neutral is not
needed. Connect one 115V line to the L (Line)
and a second 115V line to the N (Neutral
terminal).
