TPS- Installation Instructions for:
Lighting Panelboards Revise P (RP)
If model number includes W option suffix, additional
instructions follow:
The following instructions are for the installation of the
Siemens TPS and L SPD modules in Siemens Revised P
(RP) lighting panelboards.
Be aware of differences between the Revised P
and Original P panelboards. SPDs for Original P
and Revised P are not interchangeable. Original
P panelboards use TPS or L SPDs, whereas
Revised P panelboards use TPS or L SPDs or
the new TPS or L SPDs..
To determine if a customer has a Revised P panel
– look at the part number of the interior. If the
part number ends with “N” or “T” then it is a
Revised P. If it does not end in either “N” or
“T” then it is an Original P panel. For example:
PEMCA is an Original P panel and
PEMCAT is a Revised P panel. If it is a
Revised P 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 P panel ending in “N” because
it mounts in a unit space.
