Cable gland assembly procedure
Purpose
Cable glands are used whenever a cable passes through a
water-tight bulkhead or into a cabinet, to seal the opening
through which the cable passes and to protect the cable from
abrasion on the edges of the hole. Follow the guidelines detailed
here when installing cables through cable glands.
Note There are many different types of cable gland on the market.
This procedure describes the types used (now and previously) as
standard in the units manufactured by Simrad. The cable glands
are not supplied with the system.
Even though the cabinets from Simrad may be prepared for
specific types, the installation shipyard will be responsible for
selecting cable gland types and installing them.
Note The screen in transducer cables must never be connected to
ship’s ground in the cable glands!
General procedure
1 Ensure all the cables to be connected are completely
isolated from any power sources.
- I.e. Switch off and remove the supply fuses from any
units or systems into which the cables are already
connected.
2 Select the cable to be connected into the cabinet, and
select the cable gland through which the cable is to pass.
Note A minimum of 5 cm (recommended 5 - 10 cm) of slack cable
must be allowed, both inside and outside the cabinet, when
installing cables. This is to allow for vibration damping,
maintenance and measurement errors. Always double-check
your measurements before taking any irreversible actions.
3 Depending on whether the cable has already been installed
in conduits, either.
f (installed) measure the maximum length of cable
required to reach from the final cable clip outside the
cabinet to the terminal blocks inside the cabinet, add 20
cm, then remove the excess cable,
or:
g (loose cable) measure the maximum length of wire
required to reach from the cable gland to the terminal
blocks inside the cabinet, add 20 cm. and mark the
cable.
