Generator operation
3.8.1 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.
3.8.2 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.
➤ A generator with insulation monitoring must not be connected to another insulation monitoring
device as these monitoring devices can then have counter effects.
➤ Ground fault current (F1) protection switches do not function in unearthed networks (IT network
such as provided by the generator). The isolation provided by the generator, however, makes a
further ground fault current protection switch unnecessary.
➤ Follow the regulations of the local electricity supply utility and obtain any necessary permits.
➤ When cleaning the inside of the machine do not direct water or steam jets directly at the gener‐
ator or terminal box.
➤ Check regularly that all electrical connections are tight and in proper condition.
3.8.3 Connecting extension cables
➤ When operating the generator, observe the regulations regarding the connection of extension
cables.
Bear in mind:
■ In IT networks, the total length of power cables may not exceed 250 m (DIN VDE 0100, Part
728 / IEC 60364-5-551).
■ Use at least H07RN-F cables to DIN VDE 0282 Part 4 (IEC 60245-4 / HD 22.4) as non-fixed
extension cables.
