Lay cables carefully to protect against damage from:

• Direct environmental factors, such as precipitation

• movement (e.g. from wind)

• Indirect environmental factors, e.g. snow or ice,

which slip down behind the modules, and

• Chaffing on the insulation due to the cable

moving (e.g. from wind or ice).
