4.4.4 Cable of main power input
Power cable should meet the IECA S-19-81 standard, 600V insulated wire, Hypalon. Please choose
wiring size of power supply under 1.25 safety margin of maximum load. Wire diameter,
cross-sectional area, and current can refer to table 5.2. All on-site supply of cables and wires,
equipment and field wiring, cable wire terminals and equipment are necessary to comply with various
regulations and engineering requirement. Power cables shall be with braid sleeve and able to avoid the
interference with others. The power cable connection is showing on figure 4.6. Please double check the
phase sequence when wiring.
Note：1. The power cable gland should be insulated properly with heat shrinking tube
2. The power cable shall sustain the maximum permissible current under 90℃ (40℃ ambient
temperature)
