2.6 Torque Restraint

2 2
Shaft-mounted geared motors require a suitable torque
restraint to resist the reaction torque. Torque arm with
mounting sets are available as an option (see 6.7.1 Torque
Arm Set). It is always important to ensure that the torque
arm does not create excessive constraining forces due to
the driven shaft running untrue, for example. Excessive
backlash can result in excessive shock torques in switching
or reversing operations.

2.7 Final Assembly

Always assemble the hollow shaft cover with the delivered
screw as shown in Illustration 2.3.

1. Remove the eyebolt and cover the hole with the
plastic cap (supplied). This ensures the hygienic
features of a smooth surface.
2. Assemble the hollow shaft cover with the 3
screws (delivered) onto the VLT
The tightening torque is 4.5 Nm.

2.8 Electrical Connection

When connecting the motor, take note of the data on the
nameplate, the connection diagram, and the relevant
safety regulations and rules for the prevention of
accidents.
Unless a special design is concerned, the data on the
nameplate refers to ± 5% voltage tolerance, to -20 to 40°C
ambient temperature and altitudes up to 1000 m above
sea level.
When closing the terminal box, pay particular attention to
obtaining a perfect seal.
To guarantee electromagnetic compatibility (EMC) as
defined in EMC Directive 2004/108/EC, all signal lines must
use shielded cables. The cable sheath must be earthed at
both ends. The frequency inverter operating instructions
indicate whether a shielded cable is necessary for the
motor supply line. A shielded motor cable is not required
when connecting to the low-voltage network or to a
frequency inverter with an output filter. Always use
shielded cables when laying Signal cables and power
cables parallel to each other.
