Electrical Connection - Scheppach Precisa 3.0 Originalbetriebsanleitung

Electrical connection

The installed electric motor is completely wired ready for
operation.
The customer's connection to the power supply system, and
any extension cables that may be used, must conform with
local regulations.
Motor braking unit
The machine is fitted with an automatic motor braking unit
which becomes effective as soon as the driving motor is
switched off.
Important information
The 230 V/50 Hz and 400 V/50 Hz electric motor is de-
signed for the S6/40% operating mode. The motor auto-
matically switches off if it is overloaded. The motor can
be switched on again after a coolingdown period (varies
timewise).
Faulty electrical connecting leads
Insulation damage often occurs at electrical connecting
leads. Causes include:
• Pressure marks caused when connecting leads are run
through windows or the cracks of doors.
• Folds caused by the improper attachment of running of
the connecting leads.
• Cuts resulting from the crossing of the connecting lead.
• Insulation damages caused by the ripping out of the
connecting lead from the wall socket.
• Cracks due to the ageing of the insulation. Faulty electri-
cal connecting leads such as these may not be used and
are highly dangerous due to the insulation damage.
Check electrical connecting leads regularly for damage.
Ensure that the connecting lead is not attached to the
mains supply when you are checking it.
Electrical connecting leads must correspond to the relevant
VDE and DIN regulations. Only use connecting leads with
the code H 07 RN. The type designation must be printed
on the connecting lead by regulation.
Single-phase motor
• The supply voltage must be 230 V/50 Hz.
• Extension leads up to 25 m in length must have a cross-
section of 1.5 mm . Extension leads whose length is over
2
25 m must have a cross-section of at least 2.5 mm
• The mains connection is fused with a 16 A slow-blow fuse.
Three-phase motor
The 400 V/50 Hz electric motor is designed for the S6/40%
operating mode.
• The supply voltage must be 400 V/50 Hz.
• The mains connection and the extension lead must have
5 wires = 3 P + N + PE.
• The extension cables must have a minimum cross-sec-
tion of 1.5 mm .
2
• The mains connection is maximally fused with a 16 A fuse.
• The phase-sequence must be checked if the mains con-
nection or the location is changed. The polarity must be
changed, if necessay (wall socket).
Connections or repairs on the electrical equipment may only
be carried out by an electrician.
Please give the following information if you have any
enquiries.
• Motor manufacturer
• Kind of current
• Machine type label data
