Units that include the ACTIVE SURGE MONITOR optionSee MODEL NUMBER CONFIGURATION on page 4-5 to verify the SPDs monitoring option

Refer to quick start guide QS-70100 or manual IO-70109 for additional installation and operation instructions.


Environment: The unit is designed for operation indoors in ambient temperatures of -35ºC (-31ºF) to +85ºC (+185ºF) with a relative humidity of 0% to 95% (non-condensing). The unit is provided in an industrial enclosure, which should not be installed in areas with excessive dust, corrosive vapors, flammable materials or explosive atmospheres.

Mounting: Mount unit as close as possible to the service panel in close proximity to the breaker that will feed the SPD. For best performance, unit should be positioned so that the length of the wiring to the surge protective device (SPD) unit is minimized. Dimensional information is shown on page 7.

NEMA 4X (Non-Metallic) enclosure - Remove the cover from the unit to gain access to the mounting holes inside the case. Use #6 x 3/4” self-threading screws (provided), to mount the SPD to the wall or back plane. Replace the cover on the unit and torque cover screws to 10 IN-LBS, (see drawing). NEMA 12/4, (Metallic) enclosure – Mounting flanges accept 1/4 hardware.

Wire Sizing/Routing: To reduce the wiring impedance to surge currents, the phase, neutral (if required), and ground conductors are recommended to be 12AWG-10AWG and twisted together and routed in the same raceway (conduit). Avoid any sharp bends in the conductors. All wiring must comply with the National Electrical Code (NEC) and applicable local codes.

Conduit Connection: The SPD wires should feed through the plastic conduit piece supplied. The conduit should be cut to match the distance from the unit to electrical panel. Use the supplied conduit hub to connect to the electrical panel.

Wiring Connections: Before making connections to the unit, verify that the unit model number and nameplate voltage rating are appropriate for connection to the intended power source (See table).

1. It is recommended that a 20A (with 12 AWG wire) or 30A (with 10 AWG wire) circuit breaker be used for installation and connection to the service panel.

2. Connect a white wire from the supply neutral to the neutral terminal/lug inside the SPD, and connect a green wire from the source ground to the SPD ground terminal/lug.

3. Connect a black phase wire from each line on the service panel/circuit breaker to each corresponding phase terminal/lug in the SPD.

4. If using remote sensing (Form C dry contact), connect wires to COM (orange), NC (blue), and NO (yellow) respectively. Relay’s maximum switching capacity is 250VAC, 5A.

CAUTION - FOR PROPER AND SAFE OPERATION, NEUTRAL AND GROUND MUST BE RELIABLY CONNECTED. FAILURE TO OPERATE

THIS UNIT FROM A SOLIDLY GROUNDED POWER SOURCE OF THE PROPER CONFIGURATION WILL REDUCE OR IMPEDE OPERATION, AND MAY RESULT IN UNIT FAILURE.ATTENTION - Pour un fonctionnement correct et sûr, le neutre et la mise à la terre doit être connectés de manière fiable. Défaut de faire fonctionner cet appareil à partir d’une source d’alimentation solidement mise à la terre va réduire ou même empêcher le fonctionnement correct et peut entraîner une défaillance de l’unité.

Applying Power: Apply power to the SPD and assure status indications are normal. Under normal conditions, the green “OK” or “PHASE” LED(s) are illuminated and the red “REPLACE” or “SERVICE” LED is OFF. If normal status indication does not exist, see “TROUBLESHOOTING”.

PRODUCT RATINGS AND LIMITATIONS

Voltage Protection Rating: To obtain the voltage protection ratings (VPRs), as obtained by Underwriters Laboratories, Incorporated, in accordance with the Standard for Safety, Surge Protective Devices (SPDs), Standard 1449 Fourth Edition, marked on this product, #12 AWG wire must be utilized to connect the 445/440/430 SPD to your facilities’ power grid. Connections made with conductors other than #12 AWG may result in different VPRs.

Circuit Ampacity Limitations: This device has been investigated by Underwriters Laboratories, Incorporated to withstand, without exposing live circuits or components on power sources, a voltage of two times (2x) the device ratings, and fault currents of up to 200,000 AIC, as described in the Standard for Safety, Surge Protective Devices (SPDs), Standard 1449, Fourth Edition.

TROUBLESHOOTING

If any of the diagnostic indicators indicates a problem (i.e. red LED ON, and/or green LED(s) OUT; and/or alarm sounding), check all connections and voltages to the unit. If all connections are reliable, and proper voltages are supplied to the unit, call ASCO Surge Protection, Inc at 800-237-4567.

N-G Overvoltage Indication: If all green “PHASE” LEDs are ON and red “SERVICE” LED is also ON this indicates that the neutral to ground voltage at the connected panel may be 20 VAC or higher.

SPD WIRING & MOUNTING

CIRCUIT BREAKER & WIRE SIZE SUMMARY ALARM CONTACTS

Circuit breaker sizing for SPD installation is determined by the wire size being used for connection. Larger gauge wire will provide increased performance over a smaller gauge wire. Connection wire to a SPD should also be as short and straight as possible.
