INTRODUCTION
Transient voltage surges are short-term deviations from a desired voltage level or signal that can occur at any time. Such changes can result in an electronic
device malfunction, or cause extensive damage. Also termed "spikes", these occurrences take place as a result of magnetic field/inductive coupling or
whenever the line current is interrupted. They can originate from either inside a facility, or derive from outside utility lines. Sources within a facility involve loads
that are switched, such as electric motors that are turned ON and OFF and are addressed by devices applied at point-of-use equipment.
DESCRIPTION
Leviton's 55240-ASA, 55208-ASA, and 55480-ASA are the first line of protection designed to safeguard homes and small commercial establishments from
external sources of high voltage spikes. These TYPE 1 devices are connected between each of the two incoming Lines and Neutral.
SPECIFICATIONS
• ETL listed TYPE 1 device.
• Suppression in accordance with recommendations of ANCI/IEEE C62.11 and NEC 285.
• 40mm TPMOV fused SPD circuitry for all lines to Neutral.
• SPD enclosed in NEMA type 3R case for outdoor installation.
• Alarm is activated whenever either line loses surge protection.
• Green LED indicates surge protection is stable.
• Red LED indicates protection has failed.
LOCATION AND MOUNTING
1. Locate the SPD between the meter and the main service circuit breaker panel or connect at weather head of overhead service.
2. Mount the SPD so the Line and Neutral connections can be made while keeping hook-up leads as short and straight as possible. Avoid sharp bends and
turns, which will degrade the performance of the SPD. The weight of the SPD should be supported to avoid unnecessary stress on the wiring connections.
3. The SPD should be mounted to an electrical box or enclosure. DO NOT connect directly to electrical conduit.
TO INSTALL
IMPORTANT: TYPE 1 SPD devices should be supplemented with additional load side SPDs for maximum protection.
1. RESTORE POWER, if necessary.
2. Measure voltage at installation location between each Line and Neutral. System voltage must not exceed the specified maximum continuous RMS voltage
listed on the SPD label.
3. TURN OFF POWER at the installation location (usually by removing service to meter or disconnection of service supply by utility).
4. Switch all distribution panel circuit breakers to OFF position to reduce possibility of accidental voltage on the circuit.
5. Connect the SPD White (Neutral) wire to the Neutral service conductor, a grounding electrode conductor, or the equipment grounding terminal in the
service equipment.
For Cat. No. 55240-ASA: Connect Line 1 to one of the SPD's Black wires and Line 2 to the remaining Black wire. Refer to Figure 1.
For Cat. No. 55208-ASA & 55480-ASA: Connect Line 1 to one of the SPD's Black wires, connect Line 2 to one of the remaining Black wires and Line 3 to
the remaining Black wire. Refer to Fig. 2.
NOTE: Keep hook-up leads as short and straight as possible.
6. Restore power to SPD and switch circuit breakers to "ON" position to reconnect load. Verify that the Green LED is lit. INSTALLATION IS COMPLETE.
If Green LED is not lit and instead Red LED is lit, then re-check installation. Replace unit as required.
