Example:
When using an extension cord or a cable drum, the PRCD-S
must be plugged in between the outlet intended for power
supply (fixed installation) and the extension cable/cable
drum.
Do not use the PRCD-S
• for operating freezers and refrigerators.
• the PRCD-S switches the off in case of power outage and
prevents automatic restart when power is restored.
• as an ON and OFF switch for switching machines with
high starting currents.
PRCD-S cannot be used
The PRCD-S requires the presence of a ground wire.
If a ground wire interruption occurs during operation, the
PRCD-S switches off on all poles.
Therefore, the operation of a 2-pole voltage source (e.g.
isolating transformer, power generator, etc.) is not pos
-
sible.
Switching ON procedure
• Plug the PRCD-S mains plug into the existing outlet
• As soon as the PRCD-S mains plug is plugged in and the
PRCD-S is supplied with power, the wiring of the outlet
is automatically checked by the PRCD-S for faults and the
existence of the ground wire.
• Activate the I-ON button
7
with your bare hand
(switch ON PRCD-S manually)
Do NOT switch on with gloves!
• While the I-ON button
7
is being switched on with your
bare hand, the PRCD-S checks whether the ground wire is
free of mains voltage.
The PRCD-S can only be switched on in this case.
Important note – follow at all times:
• So that the PRCD-S can properly check for “mains
voltage on the ground wire” during the switch-on pro-
cess, the PRCD-S may not be switched on with gloves or
other insulating objects.
• The switch-on process must be performed properly,
meaning with bare hands!
