Connecting the power supply

WARNING
High electrical voltage!
Danger of severe injuries or death due to electric shock.
Make sure the relevant system component is not under pressure or
voltage before performing any maintenance or repair work.

Protect the system against being switched on.
• Select the control and sensor elements in accordance with EN ISO 13849
while taking into account the load to be transported and the
transportation speed.
• Only trained specialists are permitted to connect the motor!
• Observe regulation VDE 0100 for Germany or the appropriate regulations
for the country where the product is used.

Motor connection

• Note the existing line voltage!
• Note the electrical voltages on the motor rating plate, see "Fig. A: Motor
rating plate (example)" on page 22.
• Connect the motor as a Y-connection or a triangle connection in
accordance with the connection plans, see "Fig. B: Connection plans:
triangle connection/Y-connection" on page 22, and the connection plan in
the terminal box.
• The motor is equipped with a bi-metal switch (potential-free thermal
contact, 230 V AC, 300 mA) to monitor the temperature. Connect the
monitor so that it becomes currentless when the switch is actuated.
• Select a cable entry that prevents damage to the cable during operation.
• Connection cable option: 3 842 410 191 (M20x1.5), see "Fig. C: Cable
connection option" on page 22. Pay attention to the ballast fuse!
Checking the motor's direction of rotation
• Start the system for a maximum of 2 s and check that the motor is
rotating in the correct direction.
• Exchange any two wires to change the motor's direction of rotation
(L1, L2 or L3) see "Fig. B: Connection plans: triangle connection/Y-
connection" on page 22).
• Note: In motors with a factory-installed plug, correct the direction of
rotation in the switch cabinet or at the plug coupling (socket side). This
will simplify exchanges.
