WARNING
(1) Specification of circuit breaker and power cord is selected on the basis of unit’s maximum power (max. current).
(2) Specification of power cord is based on the working condition where ambient temperature is 40
º
C (104
℉
) and
multi-core cable with copper conductor(working temperature is 90
º
C (194
℉
), e.g. power cable with YJV cross-linked
copper, insulated PE and PVC sheath) is lying on the surface of slot. If working condition is different, please adjust the
specification according to national standard.
(3) Copper-core cable must be used.
(4) The above sectional area is suitable for a maximum distance of 15m (49-1/5feet). If it’s over 15m (49-1/5feet),
sectional area must be expanded to prevent overload current from burning the wire or causing fire hazard.
(5) Specification of circuit breaker is based on the working condition where the ambient temperature of circuit breaker is
40
º
C(104
℉
). If working condition is different, please adjust the specification according to national standard.
(6) The air switch should include magnetic trip function and thermal trip function so that system can be protected from
short circuit and overload.
(7) An all-pole disconnection switch having a contact separation of at least 3mm (1/8inch) in all poles should be
connected in fixed wiring.
4.6.3 Connection of power cord
WARNING
(1) Before obtaining access to terminals, all supply circuits must be disconnected.
(2) If units are type I electrical appliances, they must be reliably grounded.
(3 Ground resistance must be in accord with requirements of local standard.
