Making the electrical connection to the product

High electrical voltage!
Risk of serious injury or death from electric shock.

Disconnect the relevant system component before performing maintenance or
servicing.

Secure the system against being unintentionally switched on again.
• Choose the control and sensor elements in accordance with EN ISO 13849. When
doing so, factor in the load that is to be transported and the conveying speed.
• The motor may only be connected by qualifi ed personnel!
• Comply with VDE regulation 0100 for Germany, or corresponding regulations in the
country of use.
Motor connection
• Take account of the available supply voltage!
• Observe the electrical connection values on the motor nameplate, see Fig. 17 on
page 33.
• Connect up the motor in either a wye or a delta confi guration in accordance with
the connection diagrams, see Fig. 18 on page 33, and the connection 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). Connect the motor so that it is de-energized
when the switch is triggered.
• Insert the cable so it cannot get damaged during operation.
• Optional connector cable: 3 842 409 645, Fig. 19 on page 33. Pay attention to
the pre-fuse!
Checking the rotational direction of the motor
• Let the system run for no more than two seconds, then make sure the motor is
rotating in the proper direction.
• Switch any two wires (U1, V1 or W1, Fig. 18 on page 33) to switch the motor's
direction of rotation.
Please note:
For motors that come with a fi tted plug, correct the direction of rotation in the
control cabinet or at the socket contact (socket side). This makes replacement
easier.
