Special conditions for safe use:
• In case the aluminium housing is mounted in an area where the use of EPL Gb (Category 2 G) or EPL
Gc (Category 3 G) apparatus is required, the transparent cover must be installed such, that ignition
sources due to electrostatic discharge sparks are excluded.
• In case the aluminium housing or painted housing is mounted in an area where the use of EPL Db
(Category 2 D) or EPL Dc (Category 3 D) apparatus is required, the transparent cover and the painted
parts must be installed such, that danger of ignition due to propagating brush discharges is excluded.
• For models marked with material code M, Titanium Grade II, the installation instructions contain the
specification of the alloy, allowing the user determine the suitability of the equipment for the particular
application.
• From the safety point of view the circuits shall be assumed to be connected to earth.
• On units with digital display the programming function through the LCD display shall only be done
outside the hazardous area.
• In case the surge protector is used in application with protection techniques Ex nA and Ex tc, the
surge protector shall be installed with a high strength locking compound on the mounting thread.
