Spike Suppression Module
The spike suppression module consists of AC filter
capacitors and dynamic peak limiting devices with a
response time of less than 1 nanosecond. Normal mode
high frequency noise is attenuated, while high-speed,
high-energy transients are limited to a safe level.
Transformerless System
(Not Available on Top Exit Units)
The Precision Power Center can be supplied without
a transformer for use with separate power condition-
ing systems. If step-down and isolation are not neces-
sary, transformerless systems provide the packaged
power system advantages of security, distribution,
monitoring, and upgrade flexibility.
Remote Emergency Power Off (REPO) Switch
Pressing the REPO push but-
ton activates the shunt trip
mechanism of the main input
circuit breaker, shutting down
the system.
The illuminated and fully
guarded REPO button is
mounted in a wall box. The
assembly includes 50 feet
(15.2m) of 3-conductor cable for
wiring to the unit. Additional
lengths of cable are available.

Additional Features for All Systems
Floor Pedestals
In rooms without a raised
floor, the floor pedestals pro-
vide space for the bottom
entrance/exit of cables in Pre-
cision Power Center. The
height of the floor pedestals is
customer-specified. Standard
floor pedestal height range is
adjustable from 8.6 to 13.25 in. (218 to 336 mm).
Other available ranges: 6 to 8.5 in. (152 to 216 mm),
and 13.5 to 18 in. (343 to 457 mm). Non-raised floor
applications for the Precision Power Center are not
CSA approved.
Transient Suppression Plate
The transient suppression plate is a one-square-
meter plate mounted to (and bonded to) the high-
voltage junction box. It reduces the effects of tran-
sients on the ground system by providing a capaci-
tive coupling to building steel.
Phase Rotation Meter
The phase rotation meter is a hand-held instrument
with clip-on leads for connecting to the circuit under
test. The meter shows the circuit phase rotation in
"ABC" or "BAC" sequence.
The phase rotation meter can verify rotation
sequence of any circuit up to 600 volts.
