WARNING: This product can expose you to chemicals including DINP, which is known to the State of California to cause cancer, and DIDP which is known to the State of California to cause birth defects or other reproductive harm. For more information go to: www.P65Warnings.ca.gov.
NOTICE
LOSS OF SURGE SUPPRESSION
- Make certain that Surge Protective Device is disconnected from the circuit it is protecting before conducting high-potential insulation testing.
Failure to follow these instructions can result in equipment damage.
Introduction
The STFE Series combines rugged, high-energy transient protection with the original Active Tracking® Filter technology to provide protection against the full spectrum of voltage transients and surges.
Proper installation is required for maximum system performance. To ensure a quality installation, the installer should read the entire manual and follow all instructions before and during the installation.
These instructions do not replace national or local electrical codes. Check applicable electrical codes to ensure compliance. Installation of the STFE Series should only be performed by qualified personnel.
Preinstallation
Location Considerations
Environment: The unit is designed for indoor operation in ambient temperatures of -40ºC (-40ºF) to +60ºC (+140ºF) with a relative humidity of 0% to 95% (noncondensing).
Supplemental Enclosures: All units provided with terminal blocks must be installed inside an enclosure and located so as to prevent accidental contact with terminals during maintenance and service.
DANGER
HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH
- This equipment must be installed inside an enclosure and located so, as to prevent accidental contact with terminals during maintenance or servicing.
- Do not install in areas with excessive dust, corrosive vapors, flammable materials, or explosive atmospheres.
Failure to follow these instructions will result in death or serious injury.
Electrical Connections
All electrical connections must be installed by a licensed electrician. All wiring must comply with the National Electrical Code® (NEC® ) and applicable local codes.
Voltage, Current, and Power Configurations
Maximum Current Capability: The total current draw that a unit may continuously handle is provided in the Voltage, Current, and Power Configurations table below.
NOTICE
LOSS OF SURGE SUPPRESSION
- Overloading the unit can cause permanent damage.
Failure to follow these instructions can result in equipment damage.
Nominal Voltage: The nominal operating voltage for each model is provided in the Voltage, Current and
Power Configurations table below.
DANGER
HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH
- Confirm that the Surge Protective Device voltage rating on the module or nameplate label is not less than the operating voltage.
Failure to follow these instructions will result in death or serious injury.
Grounding
Input and output ground terminals must be connected for proper operation. Grounding is not only required for safety, but also for equipment performance. Incorrect grounding can reduce or impede the operation of the unit.
DANGER
HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH
- This equipment must be effectively grounded per all applicable codes. Use an equipment-grounding conductor to connect this equipment to the power system ground.
Failure to follow these instructions will result in death or serious injury.

Installation
- For units provided with a ground connection, a green (with or without one or more yellow stripes) insulated grounding conductor identical in size, insulation material, and thickness to the grounded and ungrounded conductors must be installed (ref. NEC Table 250-95) and referenced back to acceptable building ground.
- Attachment plugs, receptacles, etc. in the vicinity of the STFE Series must be of grounding type, with the grounding conductors connected to acceptable building ground.
- Terminals, lugs, and connectors used in installation must be suitable for the material of the conductors.
Conductors of dissimilar metals shall not be intermixed in a terminal or splicing.
