Programing some low end 480v VFDs the other day and wondered just what some of you do for the the safety equipmint you wear while setting the parameters. Obvioulsy a remote display would be best.
I think that may be true for some commercial operations.In many cases the controls will be adjusted by the end user of the equipment, who is unlikely to be an electrician or to be wearing any special PPE.
Would anything other than regular workwear be required ?
I am aware of the hazards of arc flash in peforming some types of work, but would not expect the set up of a VFD to be hazardous in this respect.
IME setting is normally via a keypad on the outer case of the equipment and would not expose one to risk of arc flash or contact with energised conductors.
In many cases the controls will be adjusted by the end user of the equipment, who is unlikely to be an electrician or to be wearing any special PPE.
Here in the UK the voltage is only slightly lower, at about 415, and I dont take any special precautions.
