Page 6: Installation Guide
Installation Guide Pre-installation Installation Environment This series is designed for use in adverse environments. Examples of environments with increased adverse conditions are: In locations in which freedom of movement is restricted, so that the operator is forced to perform the work in a cramped (kneeling, sitting or lying) position with physical contact with conductive parts;... - Page 7 1.4．Power Supply Requirements Input volt must be standard sine wave, effective value 400V, and frequency 50Hz. Unbalance degree of 3- phase volt must be no more than 5%. Power supply: Product model Power supply 3 phase 400V±10%/50Hz Min.

Page 18: Appendix A: Emc Suggestion For Installation And Use Of Welder
Appendix A 1. General The user is responsible for installing and using the arc welding equipment according to the manufacturer’s instructions. If electromagnetic disturbances are detected, then it shall be the responsibility of the user of the arc welding equipment to resolve the situation with the technical assistance of the manufacturer. - Page 19 any way, except for those changes and adjustments covered in the manufacturer’s instructions. In particular, the spark gaps of arc striking and stabilizing devices should be adjusted and maintained according to the manufacturer’s recommendations. 3) Welding cables The welding cables should be kept as short as possible and should be positioned close together, running at or close to the floor level.
