PROTECTIVE BONDING (grounding) of this controller and the enclosure in which it is 
installed shall be in accordance with National and local electrical codes. To minimize 
electrical noise and transients that may adversely affect the system, supplementary bonding 
of the controller enclosure to a local ground, using a No.12(4 mm
2
) copper conductor, is 
recommended. 
CAUTION 
To prevent product damage and failure, do not connect power supply cable to PE 
terminal.

Make sure that wiring to the main power supply is disconnected from the site AC source 
before installing wiring.
