Tampering with the noise control system is prohibited!
Federal law prohibits the following acts or causing thereof:
■
The removal or rendering inoperative by any persons, other than for purposes of maintenance,
repair, or replacement, of any devices or element of design incorporated into any new com‐
pressor for the purpose of noise control prior to its sale or delivery to the ultimate purchaser or

Generator operation
3.9.1 Comply with the protective measures against dangerous electric current
Protection against dangerous electric current is regulated by the "Low-voltage current generating
installations" directive IEC 60364–5–551 (DIN VDE 0100–551).
The protective measure concerning "isolation, insulation monitoring and shut-down" is applied. The
generator is equipped with an automatic mains cut-out with overcurrent release and insulation
monitoring in accordance with this protective measure.
➤ Observe and follow the regulations concerning protection against dangerous electric current
when using the generator.
3.9.2 Safe generator operation
Take note of the following to ensure the safe operation of the machine with a generator:
➤ Check correct function of the insulation monitoring device daily.
➤ Do not earth the neutral line (N) or connect it to the common protective earth/equipotential
bonding (PE).
➤ Make sure the equipotential bonding to earth is properly carried through (mains and machine
through cable to consumer).
➤ If the generator feeds a network (TN network), let the network's protective measures remain
effective or create another protective measure that is effective.
➤ Adjust the protective measures accordingly if the generator feeds a different network.
➤ Only a qualified electrician is allowed to carry out work on the generator or generator control
box. The electrician is responsible for the effectiveness of the protective measures provided.
➤ Do not use the generator for feeding the construction current distribution.
