In accordance with IEC 60947-1 "Standard for low-voltage switchgear and controlgear" and IEC
60947-3 "Switches, disconnectors, fuses" you require an electrical circuit breaker for the device.
We recommend commercially available automatic circuit breakers.
4.1.2
Analyzers in hazardous areas
Explosion hazard
If a flammable or ignitable atmosphere exists, plugs must never be disconnected or lamps/
fuses replaced when the analyzer is supplied with power.
Potentially explosive atmosphere
The analyzer keys must not be pressed if a potentially explosive atmosphere may be present.
If operation using the keyboard is necessary, a hot work permit is absolutely essential.
• Exceptions: Analyzers with approvals 1708 or 2022
Improper power supply
Risk of explosion in hazardous areas as result of incorrect power supply, e.g. using direct current
instead of alternating current.
• Connect the device in accordance with the specified power supply and signal circuits. The
Improper laying of shielded cables
Risk of explosion through compensating currents between hazardous area and the
non‑hazardous area.
• Shielded cables that cross into hazardous areas should be grounded only at one end.
• If grounding is required at both ends, use an equipotential bonding conductor.
