MCAC-ATSM-2014-09 Aqua tempo power series tropical air-cooled scroll chiller 50Hz
179
Only use 380~415V 3N~50Hz rated power supply for the unit, and the maximum allowable range of voltage is
342V~456V.
All electric wires must conform to local wiring connection norm. The suitable cables should be connected to
power supply terminal through wiring connection holes at the bottom of the electric cabinet. According to
Chinese standard, the user is responsible for providing voltage and current protection for the input power
supply of the unit.
All power supplies connected to the unit must pass one manual switch, to ensure that the voltages on all
nodes of electric circuit of the unit are released when the switch is cut off.
The cables of correct specification must be used to supply power for the unit. The unit should use
independent power supply, and the unit is not allowed to use the same power supply together with other
electric devices, to avoid over-load danger. The fuse or manual switch of the power supply should be
compatible with working voltage and current of the unit. In case of parallel connection of multiple modules, the
requirements of wiring connection mode and configuration parameters for the unit are shown in the following
figure.
Some connection ports in the electric box are switch signals, for which the user needs to provide power, and
the rated voltage of the power should be 220-240VAC. The user must be aware that all power supplies they
provided should be obtained through power circuit breakers (provided by the user), to ensure that all voltages
on the nodes of the provided power supply circuit are released when the circuit breakers are cut off.
All inductive components provided by the user (such as coils of contactor, relay, and so on) must be
suppressed with standard resistance-capacitance suppressors, to avoid electromagnetic interference, thus
leading to failure of the unit and its controller and even damages to them.
All weak current wires led to the electric box must apply shielded wires, which must be provided with
grounding wires. The shield wires and power supply wires should be laid separately, to avoid electromagnetic
interference.
The unit must be provided with grounding wires, which are not allowed to be connected with the grounding
wires of gas fuel pipelines, water pipelines, lightning conductors or telephones. Improper earth connection
may cause electric shock, so please check whether earth connection of the unit is firm or not frequently.
