EP-2800 Series Installation Procedures
Caution – Ungrounded power systems are inherently unstable and can produce excessively
high line-to-ground voltages during certain fault conditions. During these fault conditions
any electrical equipment, including an SPD, may be subjected to voltages which exceed their
designed ratings. is information is being provided to the user so that an informed decision can
be made before installing any electrical equipment on an ungrounded power system.
Suitable for use on a circuit capable of delivering not more than 200.000 rms symmetrical
amperes
LED Notification
• e modules come prewired for LED indication.
• ere are six wires, three black and three red, pre-
connected to a 6-pin housing.
• e LED is also pre-connected to a connector.
• Plug the 6-pin housing into the LED connector.
• Apply power after entire module installation is complete
and LED will provide visual notification of functionality.
• e green LED’s on the outside of the case indicate the
units are functioning properly. If a green LED becomes
extinguished this indicates a unit self sacrifice or
malfunction.
• e red LED’s on the modules identify which unit has
self sacrificed or malfunctioned.
Maintenance
EP products do NOT require periodic maintenance. e EP-
2800 Series provides visual and audible indications, remote
alarm with dry contacts.
It is also good practice to inspect the connections of the
power supply wiring to the EP unit monthly.
Servicing
EP units contain no serviceable parts and require no
adjustments. All EP products are designed to provide
many years of electrical protection without any need for
servicing.
Mounting
• For optimal performance mount the EP panel box
as close as possible to electrical panel.
• Can be rail mounted or bolted into wall or additional
panels with electrician supplied bolts and hardware.
• Longer wire increases inductance in the system
and the EP unit may not function properly.
• Make sure EP panel is mounted in a dry and clean
environment.
