3.4 Mechanical Installation

The power source has been designed for rack mounting in a standard 19 inch rack. The unit
should be supported from the sides with optional rack slides. See Accessory
Equipment/Rack Slides in Section 1.2. The cooling fan at the rear of the unit must be free of
any obstructions which would interfere with the flow of air. A 6.35 cm (2.5 inch) clearance
should be maintained between the rear of the unit and the rear panel of the mounting
cabinet. Adequate ventilation of the mounting cabinet must be maintained for sufficient
cooling of the power source. Use louvered side panels and/or perforated rear panels to
ensure adequate airflow. The air intake holes on the sides of the power source must not be
obstructed when mounted inside cabinet. See Figure 3-1.
The rack mount slide mounting holes centerlines on the side of the power source are 2.92
inches / 74.3 mm above the bottom edge of the front panel.
Note: The 2003RP series models cannot be mounted in a cabinet by just using
the front panel rack ears. They require additional support.

3.5 Input Wiring

The AC Power Source must be operated from a three-wire single-phase service. The mains
source must have a current rating greater than or equal to 35 A for the low input range. Use
the supplied safety cover/strain relief when connecting the input wires to the power source.
Refer to Figure 3-2 and Figure 3-6 for the input power connections.
Also loop the input ground wire through the supplied ferrite filter (Ci P/N 250508) core 5 times
(5 turns) for 230V input models (AWG#12) or 3 turns for 115V input models (AWG#10).
Enclose ferrite core with the safety cover or leave it outside the safety cover if insufficient
space is available.
When connecting the input wires to input terminal block, make sure the safety grounding wire
including the 5 turns around the ferrite core from the strain relief grommet is longer than the
Line and Neutral wires so that the ground wire will be the last to take any strain. For low-
range input operation (107/115V) #10 AWG is recommended for input wires as a minimum.
For high-range input operation (208/230V) #12AWG is recommended. For European
applications (230V), the following input cordset may also be used:
Panel Components # 86518030, rated 16A, 250V, 70 C, 3x1.5mm² conductor size, VDE
approved. Install as described above for discrete wiring.
