Electrical data
The electrical data depend on type and number of the separately certified devices installed
and shall be taken from the respective certificates and operating instructions manuals.
Notes for manufacture and operation
1. The explosion protected power distribution, switchgear and controlgear-combinations
shall be electrically connected to the equipotential bonding system of the hazardous area.
2. When intrinsically safe circuits are used which provide different protection levels
(ia, ib or ic), the marking and the field of application of the equipment is determined by that
intrinsically safe circuit having the lowest protection level.
3. The specifications and notes given in the certificates as well as the operating instructions
of the built-in, separately certified apparatus shall be considered accordingly.
4. Only certified cable glands shall be used. Non-used openings shall be sealed by
appropriate blind plugs.
