Commissioning
The five safety rules of electrical engineering must be followed:
- Disconnect the equipment from the power supply.
- Install safeguards to ensure that the power cannot be turned on
again.
- Confirm that the equipment is de-energized.
- Earth (ground) and short-circuit the equipment.
- Cover or provide barriers for adjacent energized equipment.
7.1
Density Monitor
As an option, the circuit breaker may be equipped with a separate
density monitor for each pole. The respective operations must then
be carried out for each pole.
7.1.1
Connecting the Cable
The cable is already connected to the density monitor. The cable
entry gland is located on the rear or underside of the operating
mechanism.
• Insert the cable into the operating mechanism through the cable
gland and connect it according to the schematic diagram.
Serious personal injury or property damage can result during
commissioning if the equipment is live or energized.
Therefore:
- Make sure that the circuit breaker is disconnected from
the high voltage system.
- Make sure the circuit breaker is earthed (grounded).
