DANGER
Risk of fatal injury caused by contact with live components!
➤ Check correct function of the insulation monitoring device daily (see chapter 7.5).
➤ Have the generator and control box checked annually by a qualified electrician (see
Overview:
■ Note before operating the generator
■ Switch on the generator
■ Disconnect electrical consumers
■ Switch off the generator
➤ Follow instructions.
8.5.4.1 Note before operating the generator
■ The power consumption values of simultaneous electrical consumers are added.
■ The maximum continuous power loading on the generator by the connected electrical
consumers is limited by the safety cut-out.
1. Determine the consumption values of the electric consumers.
2. Do not exceed the maximum system load caused by electric consumers.
3. If necessary, reduce the number of connected consumers.
4. For sensitive devices, note the technical data of the generator and the electric consumer.
5. Check that electric consumers and their connecting cables are in perfect condition.
6. Note the labelling of the individual sockets on the generator control cabinet regarding voltages
and amperages.
7. Always connect electric consumers to the sockets one after another.
8. Start electric consumers one after another.
9. Consumers with unfavourable starting characteristics (e.g. high starting current) should be
started first.
