e.g. power cable with YJV cross-linked copper, insulated PE and PVC sheath)
is lying on the surface of slot (IEC 60364-5-52). If working condition is changed,
please adjust the specification according to national standard.
(3) Specification of circuit breaker is based on the working condition where
ambient temperature of circuit breaker is 40
℃
. If working condition is changed,
please adjust the specification accordingly.
(4) Install cut-off device near the unit. The minimum distance between each stage
of cut-off device should be 3mm.
3.3 Wiring Work
3.3.1 Requirements for Wiring Work
(1) The unit must be grounded securely, or it may cause electric shock.
(2) The capacity of power supply must be sufficient. The sectional area of wires in
the room should comply with relevant selection requirements and be installed
with circuit breaker for branch circuit.
(3) The unit should be powered by independent circuit and specific socket.
(4) Install circuit breaker for branch circuit according to related regulations and
electrical standards.
(5) All wiring must use pressure terminal or single wire. Multi-twisted wire that
connects directly to the wiring board may cause fire hazard.
(6) Keep cable away from fan and other motional parts.
(7) Do not alter the inner wires of unit. Manufacturer does not assume responsibility
for damage or abnormal operation due to this reason.
(8) If the unit is installed in places with strong electromagnetic interference, it's
recommended to use twin-twisted shield wire. During wire connection, please
pay attention that the metal shield layer of the twin-twisted wire must be
grounded (outer case) in order to prevent the unit from electromagnetic
interference.
(9) The communication wires should be separated from power cord and connection
wire between indoor unit and outdoor unit.
3.3.2 Connection of Wires and Wiring Board Terminals
(1) Connection of single branch wires
1) Use a stripper to strip away about 25mm of the insulation layer at the end of
