Power supply
Isolators for non-earthed conductors
■
The integral ON/OFF switch must simultaneously
isolate all non-earthed conductors from the mains
with a minimum contact separation of 3 mm.
■
Install an isolator in the power cable to provide
omnipolar separation from the mains for all active
conductors, corresponding to overvoltage category
III (3 mm) for full isolation. This isolator must be fitted
in the permanent electrical installation in line with
installation requirements, e.g. mains isolator or
upstream circuit breaker.
