This function is only active or activated if the power generating set has an "insulation
monitoring" option installed. If an insulation error is present, the ISO fault light is
illuminated and an audible warning sounds. The error indicator remains active as long
as an insulation error is active. The insulation error can be acoustically acknowledged
with the Reset button (no. 17).
Insulation fault test facility
To test insulation monitoring, hold down the "ISO" key (16) for three seconds. Now the
test will be carried out. The insulation test status display gives information on the
functionality of the insulation monitoring. If the LED is lit red then the insulation
monitoring is not functional. monitoring is not functional.
DANGER! If the LED is lit green, then the insulation monitoring is functional and
will warn you in the event of an insulation fault.
This means that, when the warning appears, the connected consumer may
no longer be operated and must be immediately disconnected (unplugged). The
acoustic warning can be acknowledged. The visual warning will continue to be shown
even if the defective consumer is still connected. If no defective consumers are
connected, a warning will not appear.
Safety instructions:
• Before handing over the power generating set, 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 generating set must be
monitored at all times during operations. A trained operator must be present to
disable the power generating set if the warning symbol is shown, or to immediately
disconnect the consumer from the power generating set.
• We recommend that you test all consumers with the power generating set before
operations. Run the consumers on the power generating set. 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 connected to a distribution system
with a through connection (i.e. if the power generating set has an insulation
monitoring device, so-called rubber distributors or such 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 generat-
ing set 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 built-in ground fault circuit interrupters are not
guaranteed to perform reliably on ungrounded portable power generating sets (due
to the lack of a defined grounding system of the potential separation).
• Observe supplementary provisions or policy constraints for the use of the power
generating set under special operation conditions.
