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. Observe the load to be conveyed 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 27.
• 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 27, 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 27. 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 27).
• 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.
