Steps to connect the AC source and AC loads:
1. WARNING: Ensure the battery cable fuse is removed or breaker is secured in the open position.
WARNING: Ensure the AC source breaker is secured in the open position and there is no voltage on the
conductors before continuing.
2. Remove 10 mm / 0.4 in of insulation for the six AC conductors (neutral “N”, live “L” and protective earth “PE”
for the AC source and loads).
3. Insert the three AC source wires through the rectangular casing hole (cable gland for 120 Vac models and
PSW-H-8KW-230/48V) marked “AC INPUT”. Insert the “PE” protective conductor first into the
corresponding AC input terminal and tighten with a torque of 1.4 ~ 1.6 Nm (1.0 ~ 1.2 lbf⋅ft). Repeat for the
neutral “N” and live “L” conductors.

4. Insert the three AC load wires through the rectangular casing hole (cable gland for 120 Vac models and PSW-
H-8KW-230/48V) marked “AC OUTPUT”. Insert the “PE” protective conductor first into the corresponding
AC output terminal and tighten with a torque of 1.4 ~ 1.6 Nm (1.0 ~ 1.2 lbf⋅ft). Repeat for the neutral “N” and
live “L” conductors.

5. Make sure the six wires are securely connected.
CAUTION: Over-tightening the terminal screws can cause damage to the terminal, under-tightening
can cause a loose connection and excessive heat during operation, make sure to use the prescribed
torque. Ensure none of the conductor insulation is jammed between the terminal contacts.
CAUTION: Ensure the polarity is correct on all wires. Failure to do so may cause a short-circuit at the
AC source when several units are working in parallel operation.
