Voltage adaptor (V. Adapt)
You can use voltage adapter to monitor ungrounded power system with a rated voltage higher than 480 V AC/DC. IM400-1700 voltage adaptor can also be used in ungrounded power systems below 480 V AC/DC to increase the internal impedance of the device. The IM400THRN can be used with P1N ground adaptor and compatible Schneider Electric voltage transformer to monitor power systems with a rated voltage up to 33 kV.
The following three values are applicable for IM400N:
| Value | Advised Usage |
|---|---|
| None (Default) | Use when the monitored ungrounded power system rated voltage is ≤ 480 V AC/DC. |
| PHT1000 | Use
when the monitored ungrounded power system rated voltage is > 480
V AC/DC and ≤ 1500 V AC/DC.
NOTE: Locating an insulation fault
can be done using the device with PHT1000.
|
| HV1700 | Use when the monitored
ungrounded power system rated voltage is > 480 V AC/DC and ≤
1500 V AC/DC.
NOTE: Locating an insulation fault can not be done using
the device with IM400–1700. This value cannot be set up when
the Locating parameter is set to ON.

The following two values are applicable for IM400THRN:
| Value | Advised Usage |
|---|---|
| None (Default) | Use when the monitored ungrounded power system rated voltage is ≤ 480 V AC/DC. |
| P1N | Use
when the monitored ungrounded power system rated voltage is up to
33 kV.
NOTE: Locating an insulation fault can not be done using the
device with P1N.
