Connection to the power supply

According to the general safety precautions the electric connection of diamond core drills with water
supply is on principle to be done by a ground fault current interrupter (GFCI).
Likewise, those machines are only to be used at sockets with protective plug reception, earthed
according to the regulations.
According to those regulations WEKA core drills with water supply are provided with a PRCD inline
protector assembled between the cord.
The PRCD includes a ground fault current interrupter as well as an undervoltage breaker.
The PRCD is ready for service after connecting the electric main by pressing the ON button. If the
voltage is disconnected, the PRCD switches off and is, after the voltage returns, to start once more.
ATTENTION: Do not put the PRCD into water. It is regularly to be checked on perfect
functioning by pressing the TEST-key. Never use a core drill without a GFCI being directly
connected to the mains connection.
