Product Safety
• If the spring mechanism is operated without the circuit breaker,
the total energy stored within the spring mechanism will be
converted.
• The mechanism can be severely damaged as a result.
• If the gas pressure of the circuit breaker is below the minimum
value for mechanical operation (visible on the warning plate or
label inside the spring mechanism), then an unacceptably high
level of energy is converted within the spring mechanism.
• This can damage both circuit breaker and spring mechanism.
• Dust inside the spring mechanism can have an adverse effect on
operation of moving parts such as latches, rollers, shafts and on
the response of electrical devices.
• This can lead to malfunctions and result in damage to the spring
mechanism.
• The use of cleaning agents, rust-preventing grease or sprays may
result in heavy gum formation (gumming).
• This can have a negative effect on the operation of the spring
mechanism.
• Moisture inside the spring mechanism leads to water
condensation and subsequent corrosion of steel parts.
• This may lead to malfunctions and result in damage to the spring
mechanism.
Only operate the spring mechanism when the circuit breaker
is connected.
CAUTION
Operate the spring mechanism only with a circuit breaker in
which the gas pressure is above the minimum value for me-
chanical operation.
CAUTION
Always keep the inside of the spring mechanism free of
dust. Always close the cabinet door properly.
CAUTION
The heating unit (anticondensation heater) must always be
in operation, regardless of circuit breaker location.
