10. Electrical connection
The electrical motor installed is connected and
ready for operation. The connection complies with
the applicable VDE and DIN provisions. The cus-
tomer'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 dam-
age regularly. Ensure that the connection cables
are disconnected 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 socket
• 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 400V / 50Hz
Mains power connection and extension leads must
be 5-core = 3 P + N + SL. - (3/N/PE).
Extension cables must have a minimum cross sec-
tion of 1.5 mm² (≤ 25m).
Extension cables must have a minimum cross sec-
tion of 2.5 mm² (> 25m).
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 product connec-
tor.

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 elec-
trician may be assigned with troubleshooting.
Operating mode / duty cycle
The electric motor is designed for operating mode
S6 - 40 %.
S6 = Continuous operation with intermittent load
40% = based on 10 min. 4 min. load; 6 min. idle oper-
ation
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.
Electrical connection test
• Switch on the machine at the on-off switch; the
sawing shaft starts up.
Attention!
Check direction of rotation
• The direction of rotation of 3-phase motors must be
checked when they are connected for the first time
or if they are relocated. If necessary the polarity
must be changed with the phase inverter (Fig. A).
• When switching off, the sawing shaft is braked
within 10 sec.

m Connections and repair work on the electrical
equipment may only be carried out by electricians.
Please provide the following information in the event
of any enquiries:
• Engine manufacturer; engine type
• Type of current for the motor
• Machine data - type plate
• Electrical control data
When returning the engine always send in the
complete drive unit with electrical control. m
