Electrical connection of the product

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.
• Electrical work may only be carried out by qualifi ed personnel!
(e.g. connecting the motor)
• Comply with the standard DIN EN 60204 (previously: VDE regulation VDE 0100)
for Germany, or the corresponding regulations in the country of use.
Motor connection
• Observe the available line voltage!
• Observe the electrical connector information on the motor nameplate,
see Fig. 41 on page 55.
• Connect the motor in either a wye or a delta confi guration in accordance with
the wiring diagrams, see Fig. 42 on page 55, and the wiring diagram in the
terminal box.
• The motor is fi tted 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. 43 on page 55.
Observe the pre-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. 42 on page 55) to change the
motor's rotational direction.
Please note:
For motors that come with a fi tted plug, correct the rotational direction in the
control cabinet or at the socket contact (socket side). This makes replacement
easier.
