Note:
The above-mentioned cable selection is based on “wiring requirements at ambient temperature of
40°C”, and the relevant local specifications shall be referred to specifically;
The site must be equipped with a leakage protector and the unit must be grounded securely.
In case there are differences in the site conditions (if there are derating conditions), please refer to
the IEC standard and cable manufacturer requirements for model selection;
Only use the copper wire for the power cord.
The above wire diameter and the specification for the circuit breaker are only for each single
module, and for the total circuit breaker and the power line’s specification, their selection shall be
determined according to the total load, and you can contact York’s after-sales personnel
3.4. Installation and wiring of the unit
3.4.1 Power distribution diagram of system
Caution: The circuit breaker shall be provided by the user. The whole system is composed of 1-8 modules.
3.4.2. See the diagram of electrical principle for power supply’s connection mode of single module
Caution:
For all the user’s cable termination, it must be connected after the pressure welding of the copper terminal, and it is
strictly prohibited to directly coil the cable on the binding post;
After the wiring of the power line of the unit is completed, the construction personnel need to lock the cable locks,
which is on the side of the electric cabinet, tightly, in order to prevent water leakage.
Wire inlet and outlet hole of the unit electric cabinet: wire incoming should be performed according to the label on
the electric cabinet.
Emphasis: After the wire connection is completed, the operator must lock the cable lock on the lower part of the electric
cabinet to prevent water from entering the electric cabinet. At the same time, in order to prevent water from entering the
electric cabinet directly through the sheath, it is necessary to prevent the sheath from forming the U-shaped bend.
