6 External Security Switch 1000V / 25A
Use this switch to disconnect the PVPM from the PV power before connecting or disconnecting the measuring
cables to/from the PVPM. This avoids damages of your own health or the PVPM.
Handling:
Turn the knob at the switch in a neutral position “0” (both “0” positions are equal).
Put the measuring cable delivered with the PVPM as far as possible to the sockets at the switch housing, red
connectors to red sockets and black connectors to black sockets. You can reverse the two red connectors
without harm, the two black ones as well. Now connect the cables mounted at the switch to the PVPM (red to
red, black to black).
Before you can make a measurement you have to turn the knob at the switch to one of the “1” positions. After
the measurement turn the switch again in position „0 “! Afterwards the wiring at the PVPM can be removed
safely.
Security advice
CAUTION: Do never forget to switch to “0” before handling the connectors at the PVPM!
If you detect a defect at the switch, the housing or the connection cables, the switch must not be
used any longer under any condition!
Only specially instructed professionals must do repairs!
Keep the switch and cables away from liquids, dust and dirt. Clean the surface with a damp cloth
only.
