Installation Instructions for Eaton Surge Protective
Device xxPHxxxxx and xxPVxxxxx
EATON www.eaton.com
Introduction
Eaton’s PH and PV products are premium Surge Protective Devices
(SPDs) with filtering . They are applied to protect sensitive electronic
equipment (critical loads) from transients and electrical line noise .
Correct installation is critical for the proper operation of the Eaton
PH and PV devices . Please read the entire installation and operating
instructions prior to installing the Eaton PH or PV devices .
Safety Precautions
WARNING
IMPROPER INSTALLATION COULD CAUSE DEATH, INJURY AND
EQUIPMENT DAMAGE. FOLLOW ALL WARNINGS AND CAUTIONS.
COMPLETELY READ AND UNDERSTAND THE INFORMATION IN THIS
MANUAL BEFORE ATTEMPTING TO INSTALL OR OPERATE THIS
EQUIPMENT.
WARNING
IMPROPER WIRING COULD CAUSE DEATH, INJURY AND/OR EQUIPMENT
DAMAGE. ONLY LICENSED/QUALIFIED ELECTRICIANS WHO ARE TRAINED
IN THE INSTALLATION AND SERVICE OF ELECTRICAL SERVICES ARE TO
INSTALL AND SERVICE THIS EQUIPMENT.
WARNING
HAZARDOUS VOLTAGES ARE PRESENT INSIDE THE SPD DURING NORMAL
OPERATION. FOLLOW ALL SAFE PRACTICES TO AVOID ELECTRICAL
SHOCK.
Operation
Properly installed, Eaton’s PH and PV devics will protect electronic
equipment from surges and electrical line noise . They are installed
in series with the load to be protected . Under normal conditions,
the Eaton PH and PV devices will only draw a small capacitive cur-
rent from the line . When electrical surges or line noise exists, the
Eaton PH and PV devices will remove that portion of the distur-
bance .
Preparation
Before installation, verify that the amperage and voltage ratings of
the Eaton PH or PV device matches the application . The maximum
amperage rating of Eaton’s PH and PV devices are identified on
the nameplate located on the side of the enclosure . The maximum
amperage of the critical load must be equal to or less than Eaton’s
PH or PV device being installed . If the amperage rating is exceeded,
the unit can overheat and fail .
To verify the voltage rating, check the nameplate on the side of the
enclosure . The maximum voltage will be the same from Line to
Neutral (L - N), Line to Ground (L - G), and Neutral to Ground (N - G) .
This makes the Eaton PH and PV devices suitable for bonded sys-
tems that are L, N, G as shown in Figures 1 and 3 or for Unbonded
systems that utilize L, L, G as shown in Figures 2 and 4 . The amper-
age and voltage rating is also indicated in the catalog number . The
catalog number can also be found on the nameplate .
Review the application to ensure physical space exists for the
product installation . Review and check the grounding system . All
grounding and bonding systems must meet NEC, CEC and/or appli-
cable local codes . A poor ground or grounding and bonding viola-
tions will seriously affect the ability of Eaton’s PH and PV to function
as specified .
The Eaton PH and PV input ground and output ground are internally
wired together . Loads that require a separate ground must use the
output ground from the Eaton PH and PV . Loads that are grounded
to the chassis of the equipment do not require the output ground
from the Eaton PH and PV to prevent ground loops . The Eaton PH
and PV input ground should be connected to the local ground point
in all installations .
Overcurrent protection is required to protect the distribution system
from an unlikely failure of the Eaton PH and PV or downstream load .
Overcurrent protection must be sized according to the downstream
load with an additional 1, 1 .5, or 2 .5 ampere margin for the Eaton
PH and PV capacitive current draw as shown in Table 1 . The circuit
breaker sizes shown in Table 2 are based on safety testing of the
Aegis units and represent the maximum allowable sizes .

This ampere margin is especially important for loads under five (5)
amperes . The ampere current draw of the Eaton PH and PV device
is capacitive and may increase if there is significant noise on the
power line . This will not detract from the output current rating of
the Eaton PH and PV as the current rating of the Eaton PH and PV is
based on the output current only .
An external circuit breaker in series with the load is required for a
permanently connected two-port SPD and shall be suitably rated for
branch-circuit protection in accordance with the National Electrical
Code, ANSI/NFPA-70 and Canadian Electrical Code (CEC) . See
Table 2 . Circuit Breaker Recommendations .
