Route the cable with an appropriate loop so that water can drip off

● In case of high humidity or when installed outside, water drops can move along the cable
jacket and enter the motor through the cable entry and cable gland.
If you route the cable with an appropriate loop then water doesn't enter the terminal box, but
simply drips off.
