Installation Instructions for Eaton’s Aegis Surge
Protective Device AGPHxxxxx and AGPVxxxxx
EATON www.eaton.com
Introduction
Eaton’s Aegis 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 Aegis PH and PV units. Please read the installation and operat-
ing instructions prior to installing the Aegis PH or PV.
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, Aegis PH and PV products 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 Aegis PH and PV will only draw a small capacitive current from
the line. When electrical surges or line noise exists, the Aegis PH
and PV will remove that portion of the disturbance.
Preparation
Before installation, verify that the amperage and voltage ratings of
the Aegis PH or PV match the application. The maximum amper-
age rating of the Aegis PH and PV 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 the Aegis PH or PV 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
Aegis 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 Aegis PH and PV suitable for bonded systems 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 amperage 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 Aegis
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 the Aegis PH and PV to func-
tion as specified.
The Aegis 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 Aegis PH and PV. Loads that are grounded
to the chassis of the equipment do not require the output ground
from the Aegis PH and PV to prevent ground loops. The Aegis 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 Aegis 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 Aegis
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.
Table 1. Capacitive Current
Voltage Frequency Capacitive Current
120V 50 to 60 Hz 1 amp
120V 400 Hz 2.5 amp
220V 50 to 60 Hz 1.5 amp
This ampere margin is especially important for loads under five (5)
amperes. The ampere current draw of the Aegis 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 Aegis PH and PV
as the current rating of the Aegis 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 Requirements.
