WARNING: Use properly sized cable to ensure a gas/dust tight seal at the cable gland to
maintain an IP66 rating, (M12 – 2 to 5mm), (M20 – 8 to 13mm). Take care not to lose parts
of the gland if the cap is removed.
Tip: If cable diameter is not in
the range of the M12 or M20
glands provided an approved
reducer and smaller gland can
be fitted.
