ASCO SURGE PROTECTIVE DEVICE INSTALLATION, OPERATION AND MAINTENANCE MANUAL TABLE OF CONTENTS INTRODUCTION Major Industry Nomenclature Changes Effective 2008-2009 Figure 1: NEC® Article 285 & UL 1449-4 GENERAL INFORMATION Simplified Explanation of Operation Precautionary Statement Regarding SPDs on Ungrounded Systems... -
Page 4: Introduction
INTRODUCTION Thank you for choosing an ASCO Surge Protective Device (SPD). This is a high quality, high energy surge suppressor designed to protect sensitive equipment from damaging transient overvoltages. Proper installation is important to maximize performance. Please follow steps outlined herein. -
Page 5: General Information
If any damage was found and is a result of shipping or handling, immediately file a claim with the shipping company and forward a copy to ASCO. Storage Environment This SPD should be stored in a clean, dry environment. Storage temperature range is -40°C (-40°F) to +60°C (+140°F). -

Page 7: Service Clearance
1 Ground 1 Neutral, 1 Ground Service Clearance Service clearance is needed at the front of the Model 457 unit only, 36 inches minimum is the required distance for clearance pursuant to the NEC®. Maximizing SPD Performance SPD’s must be located as close to the circuit as possible to minimize parasitic losses. Surges are high current, high frequency events that cause substantial voltage drops across conductors. -
Page 8: Cascade Surge Protection
Circuit Breaker and Disconnect Switch This Model 457 family SPD is tested and qualified as a Type 2 SPD per UL 1449 Fourth Edition and 2008 NEC®. This SPD can be installed on the load side of the service overcurrent device per 2008 NEC® Article 285. -
Page 9: Nema Type 4X Enclosure
Model 457 is approximately 5.25 in. (133 mm) deep. It will not flush mount unless there is at least 5.25 in. (133 mm) of clearance. Model 457 is not designed to flush mount on a typical 2 x 4 stud wall. -

SPDs for ungrounded systems can be installed on grounded systems with a clamping performance penalty. However, SPDs for grounded systems installed on ungrounded systems are almost certainly destined for premature failure. Call ASCO Tech Support at (800) 237-4567 for further information. -
Page 11: System Grounding
System Grounding An equipment grounding conductor must be used on all electrical circuits connected to the SPD. For the best performance, use a single point ground system where the service entrance grounding electrode system is connected to and bonded to all other available electrodes, building steel, metal water pipes, driven rods, etc. -
Page 12: Installation
INSTALLATION Common Problems to Avoid • Confirm System voltage to SPD voltage (120V SPD will fail instantly on 240V, 277V, etc.). • Locate SPD close so leads are short & straight as possible (or will seriously hurt performance). • Make sure N-G or XO bonding meets NEC® (or will prematurely fail SPD). •... -

Page 16: Surge Counter Options
If LEDs are illuminated in a manner that suggests contradictory information, there may be an internal logic problem and the unit needs replaced. If none of the LEDs are illuminated, the unit may not be installed correctly. For troubleshooting assistance, please contact ASCO Technical Support at (800) 237-4567. Surge Counter Options The surge counter registers the number of transient overvoltages on all L-N and L-G modes since the counter was last reset. -
Page 17: Dry Contact Option
9 Connected to Pin 6 Dry Contact Option Model 457 is available with optional Dry Contacts which utilize a DB-9 connector. This feature provides two sets of normally open (N.O.) and normally closed (N.C.) contacts through the DB-9 connector. These relay contacts can be used for remote indication of the SPD’s operating status. -
Page 18: Maintenance
Tip: Visually confirm N-G bonding. Be aware that a voltmeter measuring N-G can be misleading. For example, N-G voltage could read 0V because neutral and ground are at the same potential purely by happenstance, not because they are bonded. Visually confirm bonding.

Page 19: Module Removal & Replacement Instructions
Disconnect power to the SPD. Discharge internal capacitors by grounding. Unplug the 10 pin connector from the Model 457 module. Using a 7/16” socket wrench, remove the bolts on both ends of the module, and pull the module out. Make note of the location and part number of each module removed, as this part number is not referenced anywhere else on the SPD. -
Page 20: Limited Warranty
Limited Warranty ASCO warrants it’s AC panel protection products against defective workmanship and materials for 10 years (Optional warranty available) from the date of original purchase. The unit must have been installed by a qualified and licensed electrician in order to quality for Warranty coverage. -
