The projector must be switched internally between a star connection (Y), a delta connection (Δ) or a mono-
phase connection or vice versa. See “Connecting the projector with the power net”, page 48.
The power cord required to connect the projector with the power net is not delivered with the projector. It is the
responsibility of the customer to provide the correct type of power cord. The cross-sectional area of the
conductors in the power supply cord shall not be less than 4 mm
2
(10 AWG).
In single-phase operation, the power cord must be rated for minimum 300 V.
In three-phase operation, the power cord must be rated for minimum 300 V in case of a 3W+PE (208V) power
system, and minimum 500 V in case of a 3W+N+PE (230/400 V) power system. For a 3W+PE system, 208 V
is measured between the lines. For a 3W +N+PE system, 400 V is measured between the lines, 230 V is
measured between the lines and the neutral.
To protect operating personnel, the National Electrical Manufacturers Association (NEMA) recommends that
the instrument panel and cabinet be grounded. In no event shall this projector be operated without an
adequate cabinet ground connection.
The AC supply must be installed by a qualified electrician in conformance to local codes. Hardware, wire sizes
and conduit types must comply with local codes.
A readily accessible disconnect device shall be incorporated externally to the equipment for removal of the
power to the equipment mains terminals.
The building installation must be provided with a circuit breaker of max. 40 A to protect the complete unit.
WARNING: Disconnect the power to the unit mains terminals for removal of all power from the unit.
UPS requirements
The Uninterruptible Power Supply (UPS), also known as a Continuous Power Supply (CPS), must have an
output voltage of 200-240 V at 50/60 Hz and must be capable of delivering an output current of 5 A. This UPS
provides only power for the electronics and not for the light source.
The connection between the UPS unit and the UPS inlet of the projector must be done with a certified AC
power supply cord of minimum 1,50 mm² or 14 AWG and minimum 300 V.
The SP4K-B does not have a built in UPS unit.
Projector weight
Do not underestimate the weight of the SP4K-B projector. The projector weights ±155 kg (±342 lbs) without
lens and specific a SP4K-55B projector weights 175 kg (385 lbs) without lens. Ensure that the pedestal on
which the projector is installed is capable of supporting the complete load of the system. To prevent personal
injury a hoisting tool should be used to lift the projector.
Cooler weight
The cooler unit for the SP4K-55B projector weights ±31 kg (±68.3 lbs).
CAUTION: An external frame must be used to stack projectors.
