Termination module 9191/20-00-50
The required distance of 50 mm between Ex i circuits of installed isolators and non-Ex i
circuits is achieved. The device may only be operated in environments not exceeding
degree of pollution 2. "Intended use" includes complying with these operating instructions
and the other applicable documents, e.g. the data sheet. Any other use is not intended.
3.2 Personnel Qualification
Qualified specialist personnel are required to perform the activities described in these
operating instructions. This primarily applies to work in the following areas:
• Product selection, project engineering
• Mounting/dismounting the device
• Installation
• Commissioning
• Maintenance, repair, cleaning
Specialists who perform these tasks must have a level of knowledge that meets
applicable national standards and regulations.
Additional knowledge is required for tasks in hazardous areas! R. STAHL
recommends having a level of knowledge equal to that described in the following
standards:
• IEC/EN 60079-14 (Electrical installations design, selection and erection)
• IEC/EN 60079-17 (Inspection and maintenance of electrical installations)
• IEC/EN 60079-19 (Equipment repair, overhaul and reclamation)
3.3 Residual Risks
3.3.1 Explosion Hazard
Despite the device's state-of-the-art design, explosion hazards cannot be entirely eliminated
in hazardous areas.
• Perform all work steps in hazardous areas with the utmost care at all times!
• Transport, store, plan, mount and operate the device in compliance with the technical data
exclusively (see the "Technical data" chapter).
Possible hazards (residual risks) can be categorised according to the following causes:
Mechanical damage
The device can be damaged during transport, mounting or commissioning. This kind of
damage can, for example, render the device's explosion protection partially or fully
ineffective. This may result in explosions causing serious or even fatal injury to persons in
the vicinity.
• Only transport the device in special transport packaging that reliably protects the device
from external influences. Observe the ambient conditions when selecting the transport
packaging (see the "Technical data" chapter).
• Do not place any load on the device.
• Check the packaging and the device for damage. Report any damage to R. STAHL
immediately. Do not commission a damaged device.
• Store the device in its original packaging in a dry place (with no condensation), and make
sure that it is stable and protected against the effects of vibrations and shocks.
• Do not damage the device and other system components during mounting.
Excessive heating or electrostatic charge
An incorrect setup in the cabinet, operation outside of approved conditions or improper
cleaning can cause the device to heat up severely or to become electrostatically charged,
