Maintenance

Section 5 Maintenance

1. Introduction

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: Always de-energize the regulator by turning rotary switch S1 to OFF, and remove input power to the regulator by turning off the disconnect switch or main circuit breaker before opening the access door to the service regulator.

This section provides preventive maintenance for L-828 constant current regulators (CCRs) (4-10 kW/6.6 A).
