NOTES:
1. All intrinsically safe conduits/wires/cables are to enter the main control panel on the safety barrier side of the main control panel. This wiring
must not come near or in contact with any non-intrinsically safe wiring.
2. Any replacement of intrinsically safe barriers must be an identical replacement to maintain intrinsically safe circuit rating.
3. The non-intrinsically safe terminals (power rail) must not be connected to any device which uses or generates more than 250 Vrms or d.c.
unless it has been determined that the voltage has been adequately isolated.
4. The installation must meet the requirements of the National Electric Code, NFPA 70, Article 504 Resp., Article 505 and ANSI/ISA 12.06.01
5. Multiple earthing of components is allowed only if high integrity equipotential system is realized between the points of bonding.
6. Do not operate system with safety barrier cover removed.
WARNING: Substitution of components may impair intrinsic safety. For installation, maintenance or operation instructions, see instruction
manual.
