Power supply wiring line (wire diameter selection) reference table
：
1. Power wiring is control board’s wiring system to the diameter of the branch wiring
devices reference value of each unit and circulating pump units.
2.Selection for the main Line is base on 1.25 times of the sum power of simultaneously
operating device in the whole heating system
2. Unit should be separate with a independent electricity leakage protection switch, does
not allow to use one electricity leakage protection switch for multiple units
3. The unit use 220VAC 50Hz power supply, for BKDX50-200I/150: main power line’s
length
≤
4 meters, the diameter selection is 6mm2; for BKDX30-95 I/1503, main power
line’s length
≤
4 meters, the diameter selection is 4mm2.
Notice
：①
Unit with no power
cord
and plug, the user should use which follow the above
power cord specification.
②
Connect the power cord to the unit corresponding wiring
terminal.
③Above
wiring’s diameter and length represents the magnitude of the voltage
drop within 2% of the cases.
④
When the wiring length exceeds the above value,
increase the wire diameter.
⑤
Please select the wire diameter for water pump follow state
regulations based on the actual power of the pump.
⑥
Fixed-line for unit connection must
be equipped with at least 6mm2 all-pole disconnect device contacts open pitch.
