Portable power generators with ground separation and insulation monitoring can be
operated by persons other than electricians. Suitable earthing equipment is required.
Observe mandatory distribution network lengths.
Product description:
The insulation monitoring is used in ungrounded alternating current networks.
Insulation monitors are designed to trigger at the thresholds defined by current
regulations.
An insulation error is indicated visually and acoustically on power generators for fire
fighting operations. This means that the insulation error is merely shown as a warning
and the power generator is not shut down. To allow operations to continue the power
supply to the sockets is not cut off!
This means that, when the warning symbol appears, you must discontinue
operations with the connected consumer and immediately disconnect it from the
power generator (unplug).
The acoustic warning can be acknowledged by means of a acknowledge on the control
panel. The visual warning will continue to be shown even if you switch off the power
generator as long as the defective consumer is still connected. If you restart the
power generator, and no defective consumers are attached, a warning will not appear.
Safety instructions:
∙ Before handing over the power generator, draw the user's attention to the fact that
the insulation monitoring system does not cut off the power supply to the sockets,
and merely indicates the insulation error by means of a visual and audible warning.
∙ To make sure that insulation errors are detected, the power generator must be
monitored at all times during operations. A trained operator must be present to
disable the power generator if the warning symbol is shown, or to immediately
disconnect the consumer from the power generator.
∙ We recommend that you test all consumers with the power generator before
operations. Run the consumers on the power generator. If a warning is not given,
no insulation error has occurred. If warning has been given, you must have the
consumer repaired by a qualified electrician.
∙ Only one insulation monitoring device can be attached to a distribution system
with a through connection (i.e. if the power generator has an insulation monitoring
device, rubber distributors with insulation monitors are not permitted!), because
insulation monitoring devices can impact each other's performance.
∙ DC devices (solenoids, brakes, inverters etc.) can be attached to the power
generator network to be monitored. Note that insulation errors on the direct current
circuit are detected with increased sensitivity in both current flow directions.
∙ Distributors and devices with ground fault circuit interrupters are not guaranteed
to perform reliably on ungrounded portable power generators (due to the lack of a
defined grounding system/potential separation).
∙ Observe supplementary provisions or policy constraints for the use of the power
generator under special operation conditions.
∙ When using multiple power generators, or if a public power supply network is used
