Power supply
The tool should be connected only to a power supply of
the same voltage as indicated on the nameplate, and can
only be operated on single-phase AC supply. They are
double-insulated in accordance with European Standard
and can, therefore, also be used from sockets without
earth wire.
For public low-voltage distribution systems of
between 220V and 250V
Switching operations of electric apparatus cause voltage
fluctuations. The operation of this device under unfavor-
able mains conditions can have adverse effects to the
operation of other equipment. With a mains impedance
equal or less than 0.31 Ohms it can be presumed that
there will be no negative effects. The mains socket used
for this device must be protected with a fuse or protective
circuit breaker having slow tripping characteristics.
Safety hints
For your own safety, please refer to the enclosed safety
instructions.
