General
2.1 Installation requirements
Environmental conditions
The table below summarizes the physical environment in which the DPxK-32B series projector may be safely
operated or stored.

Altitude
Let the projector acclimatize after unpacking. Neglecting this may result in a startup failure of the
Light Processor Unit.
Cooling requirements
The projector is fan cooled and must be installed with sufficient space around the projector head, minimum 20
cm (8 inch) to ensure sufficient air flow. It should be used in an area where the ambient temperature, as
measured at the projector air inlet , does not exceed +35°C (+95°F).
The installation of an exhaust system is MANDATORY. The installed exhaust blower must remove an air
volume of minimum 10m
Main Power requirements
The DPxK-32B operates from a nominal 230/400V 3W+N+PE 16A 50-60Hz (Y connection) or 208V 3W+PE
27A 50-60Hz (Δ connection). The projector must be switched internally between a star connection to a delta
connection or vice versa. See "Power input setup of the DPxK-32B", page 29.
For a 3W+N+PE system, 400V is measured between the lines, 230V is measured between the lines and the
neutral.
For a 3W+PE system, 208V is measured between the lines.
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
The power cord must be rated for minimum 300V in case of a 3W+PE (208V) power system, and minimum
500V in case of a 3W+N+PE (230/400V) power system.
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. 40A to protect the complete unit.
WARNING: Disconnect the power to the unit mains terminals and unplug power cord at UPS inlet
for removal of all power from the unit
