Note:
On 200 A standard ATSs, the white TVSS wire must be connected
to the male flag receptacle on the neutral bar. Remove the female flag con-
nector from the neutral bar. Cut the female flag connector off of the white
wire from the main wiring harness and the red wire from the optional load
shed if installed. Strip 0.25 in. (6.35 mm) of insulation from the white
TVSS wire, the white wire from the main wiring harness, and red wire from
the option load shed if installed. Crimp the supplied female flag connector
on the wires so they can be connected to the male flag terminal on the
neutral bar.

Neutral Bars.
Step 13:
The green / yellow wire from the TVS will be connected
to the ground bar. Cut the green / yellow wire to a suit-
able length to connect to the ground bar then strip 0.25
in. (6.35 mm) of insulation from the end of the wire.
Step 14:
Secure the green / yellow TVSS wire to a receptacle on
the ground bar using a blade screwdriver (see Figure
60).

Bar.
Step 15:
Using the wires cut from the red and black TVSS wires
in Step 8 (if long enough), or 600 V 14 AWG wire, make
two (2) wire leads that will run from the TVSS fuse block
to the male spade connectors at the utility lugs on the
contactor.

Lugs.
Step 16:
Remove the wiring harness connections at the male flag
terminal at the N-1 utility lug. Remove the crimp on
female flag connector. Strip 0.25 in. (6.35 mm) of insu-
lation from the end of the TVSS wire and the N-1 har-
ness wires. Using the new crimp-on female flag
connector supplied, connect the N-1 harness wires with
one of the TVSS leads.
Step 17:
Repeat the process for the N-2 wires.
Step 18:
Reconnect the N-1 and N-2 female flag connectors to
the N-1 and N-2 male flag terminals at the utility lugs.
Step 19:
Apply utility (Source 1) power and place the generator
control selector switch in the “AUTO” position after the
externally mounted TVSS has been installed. Test the
system for proper functionality.
