Hello
I have this problem.
I am about to purchase a twin screw feeder to be situated in a Zone 1 area.
The feeder is for pharmaceutical powders, therefore low tolerences, high Ra value on surface finish etc.
The motor itself on the feeder will already be ATEX approved.
The problem is the...
I have a ATEX certified Motor being situated in a Zone 1 Hazardous area.
I require an inverter to make the moter twin speed.
The invertor will be in a IP65 rated panel in safe area.
Does the inverter need to be ATEX approved.?
If the inverter is not ATEX approved will it void the motors...
