7. An external circuit breaker is not necessary for over-current protection for most units (LPL Units require a 30A or less circuit
breaker). However, it is recommended that the SPD be connected in series with a circuit breaker denoted in the tables below
(also indicated on the “Dimensional Information” pages in this manual). The SPD shall be connected in accordance with all
national and local electrical codes.
5. Connect black wires (line or phase) marked L1/A, L2/B or L3/C, the white wire (neutral) marked N, and the green wire (ground)
marked G, of the SPD using the wire range listed below. To yield the best performance of the SPD within the electrical
distribution system, keep all conductors as short as possible and avoid sharp bends.
If the SPD model is a Wye configured unit (4W+G),
and a Neutral connection is not available, please contact factory.
Voltage Protection Rating. To obtain the suppression voltage ratings (VPRs), as obtained by Underwriters Laboratory,
Incorporated, in accordance with the Standard for Safety, Surge Protective Devices (SPDs), Standard 1449, Third Edition, released
(2009), marked on this product, the suggested wire size must be utilized to connect the unit to your facilities power grid.
Connections made with conductors other than the size provided may result in different VPRs.
6. Connection to Form ‘C’ contacts shall be with #18 – 22 AWG. The ratings of the Form ‘C’ contacts are 5 amps at 250 VAC
maximum with a power factor of 1.0. For additional information on Interceptor II connections, see page 15.
7. Apply power. The surge protector is fully operational when the GREEN LEDs on the modules and the front door of enclosure are
illuminated. If the GREEN LEDs are extinguished or a RED LED is illuminated, check to ensure that power is applied to the SPD.
If an abnormal indication is present, remove power to the SPD and contact Liebert/Emerson Network Power Surge Protection
at 1-800-288-6169 or 1-607-721-8840.
8. Periodically monitor the status of the LEDs. Reduced protection exists if the GREEN LEDs are extinguished or the RED LED is
illuminated. Please contact Liebert/Emerson Network Power Surge Protection at 1-800-288-6169 or 1-607-721-8840.
9. The protection modules in these SPDs may be replaceable, contact Liebert/Emerson Network Power Surge Protection for
replacement. (Note: ACV does not have replaceable modules).
