glands. The dimensions, the clamping ranges for
cables and wires and the torques are shown in
the tables in Annex A (page 18).
If other cable and conductor entries are in -
stalled, the required torques and cable diam-
eters will be found in the appropriate manu-
al.
If any cable and conductor entries are not used
or are no longer needed, the tapped holes and
redundant gland bodies must be blanked off with
suitable blind plugs or caps.

Initial test
5.1
Switch and control gear combinations
without test port (only applies to
polyester enclosures)
In the case of explosionproof control gear com -
binations (with components that do not give off
arcs or sparks) without a test port, the routine
test was carried out with a pressure half-value
time of 180 seconds. Further testing on site is not
required.
If the explosionproof control gear combinations
have to be opened for maintenance or repairs
contrary to the above conditions, an additional
pressure half-life test must be carried out.
The enclosure is tested with an overpressure of
0.3 kPa (3 mbar). The length of time needed to
reach half the pressure 0.15 kPa (1,5 mbar) shall
be at least 180 seconds .
