Electrical Connection - Scheppach kw 7.0 Originalanleitung

Attachments must be made safe with lighting equip-
ment if the tractor unit is concealed by the attach-
ment. It is necessary to ensure that front ballast is
installed when transporting a machine with an agri-
cultural tractor, if this is required according to the load
table for the tractor. The transport speed must not
exceed 6km/h.

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 connecting
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).
The mains connection is protected with a 16 A slow-
blow fuse. The RCD 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 turning
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 operation
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.

m Connections and repairs of the electrical equip-
ment should only be carried out by an electrical spe-
cialist.
In case you have further questions, please specify
the following:
• Motor manufacturer; Current type of the motor
• Type of current for the motor
• Information of the machine type label
• Information of the switch type label
If you send the motor back, always return the
complete power unit with electro-control. m
