Fire Safety
Observe the following rules during installation:
WARNING
Improper cabling
Risk of explosion
·
Never route detector line cables and
cables which lead to the intrinsically
safe area through the same cable gland.
·
Observe the minimum creepage
distances during installation.
·
All detector line cables are lead into or out of
the housing through a cable gland. All cables
which lead to the intrinsically safe area are lead
out of the housing through the other cable
gland.
·
Lead all detector line cables through the cable
glands in the area not at risk. Lead all cables
which lead to the intrinsically safe area through
the cable glands in the Ex area. Maintain a
minimum creepage distance of 50 mm between
the two groups of cables.
·
Use the supplied cable grippers (6) to close the
housing openings that are not required.
Close the housing (4, Fig. 1) with the housing cover
(1, Fig. 1) once the installation work is complete.
