Introduction

Thank you for choosing the Siemens TPSA9040 Residential
Transient Voltage Surge Suppressor.

Save this manual! It includes instructions for obtaining
warranty service and for returning a defective device.

Please read and understand all information in this manual
prior to installation. The procedures contained herein are
not intended to supersede local or national electrical
codes. Check all applicable electrical codes to ensure
compliance. In all instances, local and national electrical
code requirements are to be followed.

This manual provides instructions for installing the
TPSA9040 Transient Voltage Surge Suppressor (TVSS). The
TPSA9040 TVSS (Figure 1) can be mounted three ways. The
preferred way is to mount the TVSS directly to the outside of
the electrical panel equipment using the chase nipple on
the body of the TVSS. It can also be installed against a
panel/wall using installer supplied hardware, or it can be
installed using an optional Flush Mount Kit. The latter two
methods require use of additional conduit and hardware
(not provided).

The TPSA9040 provides a broad range of protection from
damaging transient voltage surges and spikes. Proper
installation is imperative to maximize the effectiveness and
overall performance of this device. This device must be
installed by a licensed electrician. The electrician should
follow the steps outlined in this manual to insure proper
installation.

Failure to follow the guidelines in this manual can lead
to abnormally high voltage being applied to the TVSS. This
may cause the TPSA9040 unit to become inoperative. The
warranty does not cover an incorrectly installed device.

Do not high potential test the electrical system with the
TVSS connected. Failure to disconnect the TVSS during

elevated voltage testing will result in damage to the
suppression components and/or other electronic compo­nents (see Safety Information).

Safety Information

Note: Siemens products are extensively tested to industry
standards as set by IEEE C62.41 and C62.45, for Categories
A, B, and C. The TPSA9040 is listed to the most recent
edition of UL 1449. This product is suitable for installation

on electrical distribution equipment capable of delivering
not more than 25,000 rms symmetrical amperes.

During installation into an electrical system, the TPSA9040
must NOT be energized until the electrical system is
installed, inspected and tested. All conductors must be
connected and functional, including neutral (if required).

This section provides pertinent safety information that must
be considered before installing the TVSS.

• Do not install this device during a lightning storm.

• This device is rated NEMA 4X. Suitable for indoor
and outdoor applications. The conduit nipple must be
sealed against the panel using watertight fittings (not
supplied) to ensure a watertight connection.

• Do not install the surge protector in an excessively
hot or moist location.

• Other safety considerations are listed on the
following page.

!

!!

Hazardous voltage.
Will cause death or serious injury.

Disconnect power before
working on this equipment

Verify all power circuits are de-energized before making any
connections. The voltage rating of the device and system
must always be verified before energizing the TVSS. All
electrical connections should be performed by a qualified
(licensed) electrician. All wiring must comply with the
National Electrical Code (NEC) and applicable local codes.

• Maintenance of this Transient Voltage Surge Suppressor
should be performed by qualified electrical personnel
only.

• During normal operation, hazardous voltages are
present inside the unit.

• When servicing this unit, be sure to follow all electrical
safety precautions.

• All power sources to this unit should be locked off
before servicing. This will prevent the risk of receiving
an electrical shock.

Installation

Installing the TPSA9040 TVSS:

To install the TVSS to the electrical panel equipment,
proceed as follows:

Ensure power to the electrical panel equipment has

1.
been disconnected.
Remove the screws securing the outer panel equipment

2.
cover to the electrical panel equipment (see Figure 1).
Select the location where the TVSS will be mounted

3.
(should be based on the internal configuration of the
electrical panel equipment and the physical surround­ings 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

4.
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 installa­tion (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

5.
hole toward the inside of the electrical panel equip­ment. 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).

6.

If possible, to provide extra rigidity in the installation,
attach the TVSS to the wall or electrical panel equip­ment using installer supplied hardware.

7.

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.)

• Connect the white Neutral wire to the neutral bar

using a set screw.

• Connect the green Ground wire to the electrical

panel equipment ground.

Note: Conducting dielectric and/or high potential testing

8.

will cause internal damage to the TVSS unit. DO NOT
perform dielectric or high potential tests with the phase
or neutral TVSS wires connected.

Install the panel equipment cover.

9.
Apply power to the panel equipment. LEDs will illumi-

10.
nate on the TVSS. If any connected phase LED on the
TVSS does not illuminate, remove power, check all
