WARNING
High electrical voltage!
Risk of severe injury or death from electric shock.
 Disconnect the relevant system component before performing any maintenance
or repair work.
 Secure the system against being unintentionally switched on again.
• Choose control and sensor elements in accordance with ENISO13849. Factor in
the load being transported and the transport speed.
• The motor may only be connected by qualified personnel!
• Comply with VDE regulation VDE0100 for Germany, or corresponding regulations
in the country of use.
Motor connection
• Observe the available line voltage!
• Observe the electrical power requirement shown on the motor nameplate,
seeFig. 10 on page20.
• Connect the motor in either awye or adelta configuration in accordance with the
wiring diagrams, seeFig. 11 on page 20, and the wiring diagram in the terminal
box.
• The motor is fitted with abimetal temperature monitoring switch (potential-free
thermal contact, 230VAC, 300mA). Wire the motor so that it is de-energized
when the switch is triggered.
• Insert the cable so that it cannot get damaged during operation.
• Optional motor connection with plug (AT = S), seeFig. 12 on page 20.
Observe the back-up fuse!
Checking the rotational direction of the motor
• Let the system run for no more than 2 secs., then ensure the correct rotational
direction of the motor.
• Switch any two wires (U1, V1 or W1, seeFig. 11 on page20) to change the
motor's rotational direction.
Please note:
For motors that come with afitted plug, correct the rotational direction in the
control cabinet or at the socket contact (socket side). This makes replacement
easier.
