Example:
Whenusinganextensioncordoracabledrum,thePRCD-S
must be plugged in between the outlet intended for power
supply (xed installation) and the extension cable/cable
drum.
Do not use the PRCD-S
• foroperatingfreezersandrefrigerators.
• thePRCD-Sswitchestheo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 o 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!
