Martin Professional™ Exterior 50 & 100™ system user manual
Installing a blanking plug in an unused cable gland
All unused cable glands in the Exterior 50 & 100 system must be sealed
with blanking plugs to prevent the entry of water and dust. Enough suitably
sized blanking plugs are supplied with PSUs and Splitters to cover all
possible situations.
To install a blanking plug in a cable gland:
1. See Figure 6. Check that you have the correctly-sized blanking plug
for the gland you need to seal (the correct blanking plug is a sliding fit
in the gland when the compression nut
F
is loosened).
2. See Figure 5 on page 23. Loosen – but do not remove – compression
nut
F
on the unused cable gland, insert a suitably-sized blanking plug
fully into the cable gland, then hold cable entry
C
to prevent the
assembly from rotating and tighten compression nut
F
firmly enough to
ensure a waterproof seal.
Using a luminaire cable connection box
If the cable supplied pre-installed on Luminaires is not long enough,
Martin™ can supply a gel-filled cable connection box that allows you to
make a gel-sealed waterproof connection to extend the cable.
The connection box kit available from Martin™ (P/N 90510230) includes
the box, two cable glands and a four-way terminal block. A 10 m (32 ft.)
luminaire cable extension kit (P/N 90510200) that includes the gel-filled
connection box kit is also available.
