Danger due to electric shock.
Therefore:
- Never reach into the high voltage insulation area of the
circuit breaker.
- Never touch the contacts of the circuit breaker control
system.
Follow all regional and operator-specified safety precautions.
• Check the circuit breaker carefully for damage or corrosion. In
particular, check the insulators from the ground for possible
damage.
• If corrosion is detected, take steps to prevent or control corrosion.
• Check the ventilation ports and vents in the mechanism cabinet to
make sure they are clear. Remove any blockages.
Check the heat dissipation from the anti-condensation heater. To
do so, place a contact thermometer on the anti-condensation hea-
ter and measure the temperature rise.
The anti-condensation heating unit gets hot during operation.
It can burn skin or clothing.
Therefore:
- Never touch the heating unit directly.
Check the density monitor indicator. If the indicator is not in the
green area, top up with gas until rated pressure is reached (see
"Filling the Breaker with Gas" on Page 56).
