4.6 Electrical connection
Kindly compare the tension and current values indicated on the sign with the values
of the existing power supply system before connecting the instrument.
(See chapter 3)
4.6.1 Matching the jaw crusher to the mains voltage
4.6.2 Drive motor
Drive is a 1~120 V motor or 1~230 V motor or 3~115 / 200 V motor or 3~230 / 400
V motor
The drive motors are A.C. motors. Due to the their high reduction ratio, the jaw
crusher comes to a stop in a minimum of time after being shut off.
4.6.3 Direction of rotation of drive motor
(See the arrow on the motor housing)
The 3-phase A.C. motor must show left hand rotation when looking onto the motor.
The 1-phase A.C. motor left hand rotation is secured at the factory.
Refer to:
• DIN VDE 0530, Part 8, "Terminal Markings and Direction of Rotation"
• DIN VDE 0530, Part 7 / EN 60 934-7, "Abbreviations for Models"
Make this change in the direction of rotation by interchanging two supply
conductors "L1, L2, L3" (or the supply leads "U1, U2, U3" in the socket outlet).
DANGER Voltage!
The direction of rotation may only be changed by a
trained electrician.
DANGER
Voltage!
Only a trained specialist is allowed to convert the
supply voltage from 230 to 400 volts and/or to change
the power lead.
CAUTON
Secure the electrical system!
Danger of damage due to short-circuit.
Make certain that the socket is connected to a mains
line secured with a residual current circuit breaker.
