WARNING: Before you install and wire any device, disconnect power to
the controller system.
WARNING: Calculate the maximum possible current in each power and
common wire. Observe all electrical codes dictating the maximum
current allowable for each wire size. Current above the maximum ratings
may cause wiring to overheat, which can cause damage.
United States Only: If the controller is installed within a potentially
hazardous environment, all wiring must comply with the requirements
stated in the National Electrical Code 501-10 (b).
