Aqua tempo power series tropical air-cooled scroll chiller 50Hz

4. Wiring installation

All wiring installation should be done by qualified person.

4.1 Precautions:

1. The air-conditioner should apply special power
supply, whose voltage should conform to rated
voltage.
2. Wiring construction must be conducted by the
professional technicians according to the labeling on
the circuit diagram.
3. Only use the electric components specified by our
company, and require installation and technical
services from the manufacturer or authorized dealer.
If wiring connection fails to conform to electric
installation norm, failure of the controller, electronic
shock, and so on may be caused.
4. The connected fixed wires must be equipped with
full switching-off devices with at least 3mm contact
separation.

4.3 Requirements of wiring connection

No additional control components are required in the electric cabinet (such as relay, and so on), and the
power supply and control wires not connected with the electric cabinet are not allowed to go through the
electric box. Otherwise, electromagnetic interference may cause failure of the unit and control components
and even damages to them, which thus lead to protective failure.
All cables led to the electric box should be supported independently but by the electric box.
The strong current wires generally pass the electric box, and 220-240V alternating current may also pass the
control board, so wiring connection should conform to the principle of separation of strong current and weak
current, and the wires of power supply should be kept more than 100 mm away from the control wires.

5. Set leakage protective devices according to the
requirements of national technical standard about
electric equipment.
6. After completing all wiring construction, conduct
careful check before connecting the power supply.
7. Please carefully read the labels on the electric
cabinet.
8. The user's attempt to repair the controller is
prohibited, since improper repair may cause electric
shock, damages to the controller, and so on. If the
user has any requirement of repair, please contact
the maintenance center.
