PRELIMINARY ELECTRICAL CHECK
Connect an adjustable load across the power supply output terminals, on the right side terminal
barrier strip on the front panel (see Figure 4). The load must have a dissipation rating of at least
700 Watts. Connect a voltmeter and an oscilloscope across the power supply sense terminals +S
and –S. The oscilloscope must be isolated from the source and grounded at the load. Use an iso-
lation transformer between the test equipment and the AC input power (see Figure 13).
Connect the AC input power to the line, neutral and ground terminals (see Figure 4). Turn input
power on and check the output voltage both with and without load. The output voltage can be
adjusted within the published range by using the front panel voltage control trimmer Vadj.

FAN MAINTENANCE
Under most conditions the fan requires no maintenance. Do not use the fan in an environment of
high temperature and high humidity that exceeds the temperature and humidity limits given in the
Power Supply Specifications (see Table 2). Avoid an environment where corrosive gas may be
present. If the Power Supply is used in an open or dirty area, a filter should be installed on the air
intake side of the fan to prevent the inflow of dust particles. If the Power Supply is used in briny air
care should be taken to keep the salt from entering the Power Supply.
