Herculito Operating Procedures

4.0 OPERATING VOLTAGES

The Herculitp operates with voltages between 90-240Vac, 50/60Hz.

5.0 CABLE CONNECTION

The Herculito is supplied with two 45-foot test cables. Both cables are terminated with heavy-
duty alligator clamps to connect to the device being tested. A typical cable connection for the
Herculito to a device under test is shown in figure 3 and 4. To protect the Herculito against static
discharge in the substation, always connect the unit’s ground stud to the substation ground. It is
also highly recommended to ground one side of the circuit breaker bushing during testing to
eliminate any static discharge through the Herculito.
