Procedure
1
Ensure all the cables to be connected are completely isolated from any power
sources.
For safety reasons, switch off and remove the power 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 to 10 cm) of cable slack must be allowed, both
inside and outside the unity or cabinet, when you install cables. This is to allow for
vibration damping, maintenance and measurement errors. Always double-check
your measurements before taking any irreversible actions.
3
Measure the maximum length of cable.
a
If the cable has already been installed in conduits: Measure the maximum
length of cable required to reach from the final cable clip outside the cabinet to
the terminal block(s) inside the cabinet. Add 20 cm, and remove the excess
cable.
b
If the cable has not been installed in conduits: Measure the maximum length of
wire required to reach from the cable gland to the terminal block(s) inside the
cabinet. Add 20 cm, and mark the cable.
Note
The outer insulation on the cable will extend into the cable gland to a point
approximately 5 mm outside the outer surface of the cabinet wall.
4
Carefully remove the outer insulation from the required cable length.
Be careful! Do not damage the screen!
5
Leaving an appropriate length of the screen exposed from the insulation, cut off
the remainder.
