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 ºC (104
℉
) and
multi-core cable with copper conductor(working temperature is 90 ºC (194
℉
), e.g. power cable with YJV cross-
linked copper, insulated PE and PVC sheath) is lying on the surface of slot. If working conditions are 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-
1/5ft.). If it’s over 15m (49-1/5ft.),
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 40ºC (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 (1/8in.) in all poles should be
connected in fixed wiring.
Connection of power cord
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.
4.
The Green-yellow wire within units are ground wire. Do not use it for other purposes. Nor should it be cut off or
secured by tapping screws. Otherwise, it may cause electric shock.
5.
Power supply at user side must have reliable ground terminal. Do not connect ground wire to the following
places:
1) Water pipe.
2) Gas pipe.
3) Drainage pipe.
4) Other places that are considered by professionals as unreliable.
6.
Power cord and communication wire should be separated, with a distance of more than 20cm (7-7/8in.).
Otherwise, system’s communication may not work well.
