Installation
Installing the TPSA9040 TVSS:
To install the TVSS to the electrical panel equipment,
proceed as follows:
proceed as follows:
Ensure power to the electrical panel equipment has
been disconnected.
Remove the screws securing the outer panel equipment
cover to the electrical panel equipment (see Figure 1).
Select the location where the TVSS will be mounted
(should be based on the internal configuration of the
electrical panel equipment and the physical surround-
ings outside the equipment). Note that the TVSS’s lead
length must be minimized to achieve maximum
performance. Once the location has been determined,
drill or punch a 7/8” diameter hole in the top, bottom or
side surface of the electrical panel equipment. The ideal
mounting location will also allow the TVSS to be secured
to the wall or panel in addition to using the chase nipple.
Screw one of the conduit nuts on to the chase nipple
until it bottoms out. Note: bonding of the conduit
connections to the electrical panel equipment is not
automatic, and must be provided as part of the installa-
tion (remove paint from the electrical panel equipment
surface prior to installing the TVSS and chase nipple).
Push the leads from the TVSS through the 7/8” diameter
hole toward the inside of the electrical panel equip-
ment. Push the leading part of the chase nipple through
the hole and secure the TVSS using a second conduit
nut (sandwiching the metal wall of the electrical panel
equipment between the two conduit nuts).
If possible, to provide extra rigidity in the installation,
attach the TVSS to the wall or electrical panel equip-
ment using installer supplied hardware.
Trim the leads from the TVSS as short as possible, but
still allowing the following connections to be made (see
Figure 2):

•
Black wires ( two in number ) go to the nearest
free 20 amp circuit breaker. The phase of each
lead is marked with a white band and letter
designator (L1 & L2). Connect the TVSS leads
to the appropriate phases. (It is not critical which
black wire goes to the positions on the circuit
breaker, however connect to L1 and L2 if known.)
