IV.3 PREVENTIVE
IV.3.1 FIRST MONTHS
In the first months of use, check the tightness of terminals and connections, particularly for HV or LV power
circuits :
▪
Input terminals, fuse-holders or circuit breaker, contactor
▪
Output terminals, brass straps on the load plate, all screwed connections at the back of the load
plate.
IV.3.2 ANNUAL PROCEDURE
▪
Remove dust from the bottoms of the casings to avoid accumulation, which could prevent proper
cooling.
▪
Remove dust from the electronic circuit boards and LV rack elements.
▪
Check the tightness of power connections (Lighting loop, Power, Earth)
▪
Check operative functions, in local and remote control.
IV.3.3 EVERY THREE YEARS
The frequency with which these operations are carried out will depend on the usage of the CCR:
▪
Start by a general visual inspection
▪
Check internal connections (tightness of screws and terminals),
▪
Check the correct correspondence between: current setting, displayed value, measured value (use
an insulated true RMS ammeter and clamp of sufficient accuracy)
In case of discordance, a calibration of the CCR can be carried out.
