Cable installation
Mount the cable exit in the “down” or lower hemisphere region to promote drainage after
washdown.
Create a drip loop so that any liquids or chemicals that spray or splash on to the cable will
travel down to the loop and drip off instead of running down the cable directly on to the
motor strain relief bushing.
The cable bushing could come loose or allow for contamination to get
inside the motor, if no strain relief on the cable is used. This could lead to
unexpected behavior of the motor and electrocution hazard due to failure
of electrical terminations.
13.4.1
Standard cabling
Standard cable is usable in all applications except food grade applications.
Observe the minimum bending radius for the cable (150/165 mm, see p.41).
Compatibility of the cable to cleaning solutions used in the application should be evalua-
ted before subjecting the cable to long-term exposure to chemicals. Using the motor in
food-grade applications requires the tube option for the cable.
13.4.2
Tube cabling
Silicone tubing protects the cable and electrical interfaces on these motors from exposure
to cleaning solutions and avoids emissions from the motor cable.
Observe the minimum bending radius for the cable in tube (175/190 mm, see p.41).
Exposure of the silicone tubing to strong mineral acids should be avoided to avoid chemi-
cal degradation of the silicone tubing. Compatibility of the silicone tubing with cleaning
solutions used in the application should be evaluated before subjecting the silicone tubing
to long-term exposure to chemicals.
