part number. All electrical tests performed on the unit prior to installation must be carried out
by a qualified person familiar with AC/DC powered equipment and having the specialized
knowledge required of the hazards associated with switched mode power supplies. This is
particularly essential if the unit covers are removed, which exposes many devices operating at
line voltage and some operating at peak voltages of up to 400 volts.

MOUNTING REQUIREMENTS AND COOLING

The mechanical outline drawing, contained within this pamphlet, provides the necessary
installation dimensions required for customer mounting and space allocation.
IMPORTANT: Use M4 screws for mounting. Screws must not penetrate more than 1/8"(3
MM) into the power supply. The UF1500 units have integral cooling fans and can be mounted
in any position. However mounting orientation should not oppose the system forced air
direction, the natural convection, or system cooling draft air flow. Furthermore, the power
supply air intakes and exhaust slots must not be obstructed. The intake air temperature should
be limited to allow the unit to operate in accordance with the thermal derating envelope of the
electrical specifications.

INPUT POWER CONNECTIONS

The input power terminal block is located on the chassis end that also includes the fans.
Safety earth ground is to be connected to the grounding post adjacent to the input power
terminal block.
The terminal functions are clearly shown on the top label of the unit.
Connections should be made using correctly sized wire gauges and colors as per applicable
electrical codes.
AC INPUT
Line:
Neutral:
Ground:
The ground connection must be made to a well defined, low impedance ground (protective
ground). Connections must not have loose strands and the insulation must cover the wire up
to the block itself. Interface terminal lugs must be fastened properly.
