Protection against dangerous electric current

Protection against dangerous electric current is regulated by
IEC 60364–5–551 (DIN VDE 0100–551).
The measures concerning isolation, insulation monitoring and shut-down are 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.

Instructions for safe generator operation

➤ Take note of the following for safe generator operation:
■ 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.
■ 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
generator or terminal box.
■ Check regularly that all electrical connections are tight and in order.

Connection of extension cables

➤ Observe and adhere to the regulations regarding extension cables before operating the gener‐
ator.
■ 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.

Maximum power supply loading

➤ Observe the following for maximum power supply loading of connected consumers:
■ The power consumption values of simultaneous consumers are added.
■ The maximum continuous power loading on the generator by the connected consumers is
limited by the safety cut-out.
