11. Electrical Connection
The electrical motor installed is connected and ready
for operation. The connection complies with the ap-
plicable VDE and DIN provisions. The customer‘s
mains connection as well as the extension cable
used must also comply with these regulations.
Check electrical connection cables regularly for
damage. Ensure that the connecting cable is not at-
tached to the mains when you are checking it.
Electrical connecting cables must correspond to the
relevant VDE and DIN regulations. Only use con-
necting cables with the code H 07 RN.
The type designation must be printed on the con-
necting cable by regulation.
Faulty electrical connecting cables
Insulation damage often occurs at electrical connect-
ing cables.
Causes include:
• Pinch points when connecting cables are run
through window or door gaps.
• Kinks resulting from incorrect attachment or
laying of the connection cable.
• Cuts resulting from running over the connect-
ing cable.
• Insulation damage resulting from forcefully
pulling out of the wall socket.
• Cracks through aging of insulation.
Such defective electrical connection cables must not
be used as the insulation damage makes them
ex-
tremely hazardous
.
Three-phase motor 400 V/ 50 Hz
Mains voltage 400 Volt / 50 Hz.
Mains voltage and extension cables must be 5-lead
= 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).
Electrical Connection
Connect the machine to the mains with a CEE plug.
The mains connection is protected with a 16 A slow-
blow fuse.
Switch on the machine at the operating switch; the
saw shaft starts running.
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 pole inverter in the machine socket.
Motor-brake appliance
The brake slowes down the motor of the saw shaft
within 10 seconds.
The electrical braking is interrupted after maximum
14 seconds.
In case the braking takes more than 10 seconds the
machine should not be used again, as the brake is
defective. The machine implicitly needs to be discon-
nected from the power supply. Only an electronic spe-
cialist should be instructed to repair this malfunction.
Operating mode / Switch-on duration
The electrical motor is dimensioned for
operating
mode S6 - 40 %
.
S6 = pass operation with load exposure
40% = related to 10 min. 4min. load; 6min. pass oper-
ation
If the motor is overloaded, it automatically switches
off because a thermostat protects the motor against
overloading. After a cool-down period (time varies)
the motor can be switched on again.
Check electrical connection
• Switch on the machine with the power switch, the
motor runs up.
Attention!
Check the direction of rotation!
• Three-phase AC motors must be checked for their
direction of rotation in the event of a new connec-
tion or change of location. If necessary, the direc-
tion of rotation must be changed with the phase
inverter (Fig. A)
• Upon switching off the saw shaft is slowed down
within 10 seconds.

Alternating current motor
• The supply voltage hast to be 220-240 Volt / 50 Hz.
• Extension cables must be up to 25 m long, have a
cross cut of 1.5 mm², be over 25 m long, and have
a minimum 2.5 mm².
• The mains connection is protected with a 16 A
slow-blow fuse.
• The RCD breaker must have a 30 mA trip rating.
