Grounding the Equipment Cabinet
To protect the equipment against lightning induced surges, install the cabinet grounding wires to the
MTS cabinet.
Procedure:
1 Strip the end of the wire to be connected to the station ground point in the junction panel.
2 Using an appropriate tool, attach a crimp lug onto the cabinet ground wire. Ensure that the lug is
securely fastened to wire.
3 Use a star type and a regular lock washer, which should be placed between the screw and the
lug (as shown in Figure 29: Cabinet Grounding on page 99). The regular lock washer must be
placed above the lug. The lug must have direct contact to the surface of the cabinet (no washer
of any kind between the lug and the surface to which it contacts).
