separately certified apparatus. The equipment is intended for stationary installation inside the
hazardous area.
The following separately certified, intrinsically safe equipment is intended for installation:
- Proximitor, type 3300XL, Bently Nevada
- Displacement chain, type OD-105x, Brüel & Kjaer
- Temperature transmitter, type 248R, Rosemount Inc.
- Temperature transmitter, type 644R, Rosemount Inc.
Depending on the type of protection or the protection level and the type of built-in intrinsically
safe equipment the power distribution, switchgear and controlgear-combinations can be
operated as category 1, 2 or 3-equipment (EPL Ga, Gb, Gc, or Db) under the following
markings:
II 1 G Ex ia IIC T6...T4 Ga or II 2 G Ex ib IIC T6...T4 Gb or
II 3 G Ex ic IIC T6...T4 Gc or II 2 D Ex tb IIIC T 120 °C Db or
II 3 G Ex nA IIC T6...T4 Gc
For relationship between the permissible ambient temperature, type of protection, tempera-
ture class and type of enclosure as well as the number and type of the installed devices, ref-
erence is made to the following tables. These tables apply in each case to the specified
numbers of one and the same type of equipment; a combination of several types is not per-
