2.3 Intended use
Only qualified personnel are permitted to carry out the work necessary to
install, commission and run a device or system.
The ISOMETER® monitors the insulation resistance R
to the Japanese charging standard CHAdeMO for nominal voltage ranges between
DC 50 V and 400 V. Single-pole insulation faults are reported with a response time ≤ 1 s.
Two-pole insulation faults within 10 s. The maximum permissible system leakage
capacitance C is 2 μF.
e
In order to meet the requirements of applicable standards, customised parameter set-
tings must be made on the equipment in order to adapt it to local equipment and oper-
ating conditions. Please heed the limits of the range of application indicated in the
technical data.
Any use other than that described in this manual is regarded as improper.
.
To ensure that the ISOMETER® functions correctly, an internal resistance
of ≤1 kΩ must exist between L+ and L- via the source (e.g. the transformer)
or the load.
In the event of an alarm message of the ISOMETER®, the insulation fault
should be eliminated as quickly as possible.
If the ISOMETER® is installed inside a control cabinet, the insulation fault
message must be audible and/or visible to attract attention.
