TPS4-01 Installation Instructions for:
Lighting Panelboards Revise P1 (RP1)
If model number includes W option suffix, additional
instructions follow:
The following instructions are for the installation of the
Siemens TPS4 01 and L1 SPD modules in Siemens Revised P1
(RP1) lighting panelboards.
Be aware of differences between the Revised P1
and Original P1 panelboards. SPDs for Original P1
and Revised P1 are not interchangeable. Original
P1 panelboards use TPS3 01 or L1 SPDs, whereas
Revised P1 panelboards use TPS3 02 or L2 SPDs or
the new TPS4 01 or L1 SPDs..
To determine if a customer has a Revised P1 panel
– look at the part number of the interior. If the
part number ends with “N” or “T” then it is a
Revised P1. If it does not end in either “N” or
“T” then it is an Original P1 panel. For example:
P1E42MC250A is an Original P1 panel and
P1E42MC250AT is a Revised P1 panel. If it is a
Revised P1 panel ending in “N” – then there is
no Subfeed space and no place for an SPD to be
installed internally. A different SPD like the new
Bolthshield BSPD product line can be an option
for the Revised P1 panel ending in “N” because
it mounts in a unit space.

Step 1) Lock off all power supplying this equipment before
working on it.
Step 2) Attach TPS4 Mounting Plates (Item 2, 2 Places) to
TPS4 using 10- 32 SEM screws with captive lock washers
(Item 3). The mounting plates should be attached to the
TPS4 with the offset oriented towards the top of the unit.
Torque Screws to values listed.
Step 3) Position the TPS4 unit (item 1) on the panel base rail
so that the TPS4 Phase tabs (Item 5) extend beneath the Bus
Tabs on RP1 Panel. Attached TPS4 Phase Tabs to Panel Bus
using #1/4-20 Hex SEM Screws (Item 6). Do not Torque at
this time.
Step 4) Connect the TPS4 unit to the base rail using four (4)
of the #10-24 Hex Thread Rolling screws (item 4).
Step 5) If present, connect TPS4 Neutral Connection Lug
(Item 7) to Panel Neutral using 8 AWG minimum wire.
For best SPD performance, trim wire as required to provide
shortest possible route between TPS4 Neutral connection
and Panel Neutral Connection. Route wire as straight as
possible and use gentle radius on any bends. Do not kink
wire. Prevent wire from encroaching breaker locations.
Neutral Connection is not applicable on Delta systems.
Step 6) Torque all connections to the values as specified on
the installation.
