Operating Procedures
3.5 – Normal Function Test Procedures
This section concerns with “normal function” test proce dures, and
includes all steps necessary to ensure that the unit is operating within
specified para meters prior to use. A digital multimeter (an example
is shown in Figure 3.5.1) capable of measuring dc and ac voltage
and resistance will be required to perform some of the tests. These
functional test procedures should become routine.

Check Unit for Evidence of Damage
Check for dents, punctures, case distortion or misalignment, and cracked or loose connec tors. If no damage
is evident, proceed to the next step. If damage is evident, contact Tesla™ Industries, Inc.
Check DC Voltage Reading at DC Receptacle Terminals
To verify that the power supply is functioning normally, set the digital multimeter to measure dc voltage.
Turn the unit on. Turn on both DC Output Circuit Breakers (Figure 3.6.2). As shown in Figure 3.6.3, place the
positive probe (red) on the positive post of the dc output connector and the negative probe on the negative
post. The multimeter display should read approximately 28.5 Vdc (± 0.5 Vdc). NOTE: To test each Circuit
Breaker individually, turn only one of the Circuit Breakers on at a time when testing. As in the previous test,
the multimeter display should read approximately 28.5 Vdc (± 0.5 Vdc).
