3.3 UNIT WIRING REQUIREMENTS
1. Power supply and control lines not connected to the electric control box are not allowed to pass through the
electric control box. Otherwise, electromagnetic interference may cause the unit and control devices to
malfunction or even be damaged, and will lose efficacy.
2. In the electric control box, there are generally strong current lines passing through, and the control board also
has 220V AC power passing through. The principle of separation of strong and weak power should be followed
when wiring. The operation panel connection cable cannot be bundled with the power cable.
3. All electrical circuits must comply with local wiring specifications. According to EU standards, users are
responsible for providing voltage and current protection to the input power of the unit.
4. All the power connected to the unit must pass a manual switch, and ensure that when this switch is turned off,
the voltage on the circuit node of the unit is all released.
5, must use the correct specification of the cable to provide power to the unit. The unit should use an
independent power supply. It is strictly forbidden for the unit to share the same power source with other electrical
appliances to avoid danger of overload. The fuse or manual switch of the power supply should match the
working voltage and working current of the unit.
6. The unit must be installed with a ground wire. Do not connect the ground wire to the gas fuel pipe, water pipe,
lightning conductor or telephone. Improper grounding may cause electric shock accidents. Please check the unit
grounding frequently.
7. All the lines connected to the unit should avoid rainwater from penetrating into the unit to prevent leakage
accidents.
