Maintenance
WARNING: Only personnel authorized to work on high-
voltage equipment should perform maintenance on the regulator.
WARNING: Operate regulator under local control (using rotary
switch) when performing maintenance tasks on the regulator.
This will prevent the regulator from
accidentally being turned on and causing serious injury or death.
De-energize regulator by turning rotary switch to OFF, and
remove input power to regulator by turning off disconnect
switch or main circuit breaker before opening access door to
service regulator.
WARNING: If the regulator experiences an overvoltage or an
overcurrent fault, it will enter protective shutdown mode. In this
mode, the regulator turns off until either
power to the regulator is cycled, or the regulator is turned off
with either the rotary switch or the remote controls.
This section provides preventive maintenance for L-828 /L-829 constant
current regulators (CCRs) (4-70 kW 6.6 A or 20 A).
