S&C Instruction Sheet 663-500 11
Cable Terminations
STEP 3.
To facilitate makeup and connection of cable
terminations to switch terminals, switch
interphase and end barriers (where applicable)
can be removed by loosening the wing-head
screw that secures each barrier to the barrier-
support angle. Remove the tie wraps securing
the wing-head screws for shipment. The screw
will remain attached to the barrier, which is
supported at the switch frame by the barrier
guide. See Figure 5. Lift the barrier from the
guide and place it in a location where the barrier
will not be damaged.
STEP 4.
Optional cable guides (catalog number suffi x
“-M2” or “-M3”), if specifi ed, include cable-
support brackets (packed separately) and
mounting angles (factory installed when an
optional base spacer, 12-inch (30.5-cm)
minimum, is specifi ed; packed separately
otherwise). Using the hardware furnished,
attach the mounting angles (if packed
separately) to the tabs provided on the sidewalls
of the compartments and attach the cable-
support brackets to the angles. See Figure 5. Do
not remove the protective sheet from the saddle
of the bracket or install the cable wrap until
instructed to do so in Step 5 on page 13.
