Circuit Connection - Haier HR-SC Operating Instructions Manual

Installation introduction

Circuit connection

Screw off bolts on the bottom shell of solar station, open its front shell and connect the circuit
as shown in the diagram.
Circuit connection of water storage tank
„
• The nominal cross-sectional area of the wires shall not less than 1.5mm
Conductors identified by the colour combination green/yellow shall only be
Notice
used for grounding conductors
• The wires shall provide non-detachable lining or non-detachable bushing.
The wires shall be protected so that they do not come into contact with burrs,
•
cooling fins or similar edges which may cause damage to their insulation.
• The wires shall be protected so that they do not come into contact with hot
surface, wet, or significant amounts of ultraviolet radiation except the wires are
suitable for the conditions.
1
Connect respectively L end (brown) and N end (blue) of wire of water storage tank with L
end and N end of relay. ( N label of relay represents the N electrode of power)
2
