2.3.2 Connecting the 3-phase AC power cord to the LPSU
Entrust a specialist to carry out the AC power supply work from the power supply equipment
of the building to the place of projector installation.
This document describes the connection procedure for the lamp power supply unit (LPSU)
assuming that the AC power supply construction has been completed.
[1]
Remove the terminal cover
at the top of the AC power
supply connecting terminal
of the lamp power supply
unit.
[2]
Insert three live wires of
the AC power cord into the
connection terminal and fix
them with screws.
Insert the solderless terminal into the
fixing hole of the connecting terminal and
tighten the screw with a Phillips-head
type screwdriver.
If the neutral phase is wired from the
power supply equipment, wrap the cable
end with insulation tape or the like so that
it does not contact the live section. It is
not necessary to connect the neutral
phase because this phase is not used in
this machine.
