12. m Electrical connection
The electrical motor installed is connected and ready
for operation. The connection complies with the
applicable VDE and DIN provisions. The customer's
mains power connection as well as the extension
lead used must also comply with these regulations
and the local regulations.
Check the electrical connection cables for damage
regularly. Ensure that the connection cables are dis-
connected from electrical power when checking for
damage.
Electrical connection cables must comply with the
applicable VDE and DIN provisions. Only use con-
nection cables with the marking „H 07 RN".
The printing of the type designation on the cable is
mandatory.
Damaged electrical connection cables
The insulation on electrical connection cables is
often damaged.
Causes are:
• Pressure points, where connection cables are
passed through windows or doors.
• Kinks where the connection cables have been
improperly fastened or routed.
• Places where the connection cables have been cut
due to being driven over.
• Insulation damage due to being ripped out of the
wall outlet.
• Cracks due to the insulation ageing.
Such damaged electrical connection cables must not
be used and are life-threatening due to insulation
damage!
3-phase motor 400 V / 50 Hz
Mains voltage 400 V / 50 Hz.
Mains power connection and extension leads must
be 5-core = 3 P + N + SL. - (3/N/PE).

Extension cables must have a minimum cross
section of 1.5 mm² (≤ 25 m).
Extension cables must have a minimum cross sec-
tion of 2.5 mm² (> 25 m).
The mains power connection is protected with a 16A
slow-blow fuse. The RCD circuit breaker must have a
30 mA trip rating.
When connecting to the mains or in the event of the
machine being moved to another location, the turn-
ing direction must be checked. It may be necessary
to change the polarity.
Turn the pole changing device in the device connector.
Motor braking device
The brake brakes the drive motor of the sawing shaft
within 10 s.
The electric braking is interrupted after max. 14 s.
If the braking process takes longer than 10 s, the
machine must no longer be operated because the
brake is defective. It is essential to disconnect the
machine from the power supply.
Only a qualified electrician may be assigned with
troubleshooting.
Operating mode / duty cycle
The electric motor is designed for operating mode
S6 - 20 %.
S6 = Continuous operation with intermittent load
20% = Based on 10 min: 2 min. load; 8 min. idle
mode.
If the engine is overloaded, it switches off automati-
cally because a thermostat protects the motor from
overloading. After a cool-down period (time varies)
the motor can be switched back on again.
