(1)  An all-pole disconnection switch having a contact separation of at least 3mm (1/8 inch) in all 

poles should be connected in fixed wiring. 

(2)  The circuit breaker and power cord specification in above sheet are based on max power (max 

current) of the unit. 

(3)  The power cord specification in above sheet is based on ambient temperature of 40°C (104°F). 
(4)  The circuit breaker specification in above sheet is based on ambient temperature of 40°C 

(104°F). If the working condition is different, please adjust it according to the specification sheet 
of circuit breaker.
