NOTE
►
If the converter
SAFERUN
® CMS-T was sup-
plied only briefly once with a non-intrinsically
safe power supply, the safety-related mark-
ings regarding the explosion protection on
the nameplate have to become unreadable.
►
The subsequent operation of the converter
SAFERUN
® CMS-T in the hazardous area is no
longer permitted for reasons of safety with
regard to the ex-relevant components to help
ensure explosion protection in the Ex i-cir-
cuits.
