.
2.6 Using a generator or transformer
The core drilling machine may be powered by a generator or by way of site transformer when the following conditions
are fulfilled:
AC voltage, power output at least 7.000 VA
The operating voltage must, at all times, be no more than 5% above or 10% below the rated voltage.
Frequency: 50 to 60 Hz, max. 65 Hz
Automatic voltage regulator with starting boost
NOTE
Switching other power tools, machines or appliances on and off may cause undervoltage and / or overvoltage peaks,
resulting in damage to the core drilling machine. Never operate other power tools, machines or appliances from the
generator or transformer at the same time.
3 Technical data
Right of technical changes reserved.
NOTE
The core drilling machine is available in various voltage ratings. Please refer to the core drilling machine’s type
identification plate for details of its rated voltage and rated input power.
The 110 V version of the core drilling machine is suitable only for short periods of operation with a 40% relative
switched-on time (S3 operating mode, intermittent operation in accordance with DIN EN 60034-1). After each 24-minute
period of operation at maximum load, the machine must be allowed to cool down for at least 36 minutes.
