Eaton Innovative Technology Equalizer 2 Series Surge Protective Device Quick Start Guide

1. Introduction

This Quick Start Guide provides information for the installation, wiring, and operation of Eaton's Innovative Technology Equalizer 2 Series Surge Protective Device (SPD). Installation should only be performed by qualified personnel. For comprehensive details on installation, wiring, and operation, refer to the documents listed in Table 2. For specific installation, application, or maintenance inquiries, contact your Innovative Technology Master Distributor or Eaton's Technical Resource Center at spd@eaton.com or 1-800-647-8877. This guide does not cover all variations or details of the device's storage, delivery, installation, operation, or maintenance.

1.1 Safety Precautions

⚠️ WARNING - SHOCK HAZARD - DO NOT OPEN.

WARNING - NO SERVICEABLE PARTS. ATTENTION: NO REPLACEABLE OR REPAIRABLE PARTS.

Installation must be completed by a LICENSED/QUALIFIED ELECTRICIAN in accordance with the National Electric Code (NEC), Canadian Electric Code (CEC), state, county, local safety ratings, or other applicable country codes. Local electrical codes take precedence over these instructions.

Improper wiring can result in death, injury, and/or equipment damage. Only licensed/qualified electricians trained in electrical services should install and service this equipment.

Verify that the electrical system's voltage and wiring configuration match the voltage-rating label on the SPD.

Conducting dielectric, Megger, or Hi-Potential testing with the SPD installed will cause internal damage to the SPD and will cause the test to fail.

Improper installation can result in death, injury, and equipment damage. Read and understand all warnings and cautions before attempting installation or operation.

ARC FLASH DURING INSTALLATION CAN CAUSE INJURY OR DEATH. Use appropriate safety precautions and personal protection equipment for arc flash protection.

Ensure the facility's grounding system is adequate. All grounding, bonding, and earthing practices must meet NEC, CEC, and local approved practices. A poor ground or bonding violation will significantly impact the SPD's specified function.

Installing an SPD with an improper voltage rating for the electrical system can create a hazardous condition, leading to injury or equipment damage.

When mounting the SPD outdoors, use weatherproof conduit and fittings to maintain the enclosure's NEMA rating.

For use on circuits delivering up to 5000 RMS Amps.

1.2 Enclosure Dimensions

Refer to the document listed in Table 2 for unit size and dimensions.

1.3 Directly Mounted to Electrical Panel – Preferred Method

The preferred installation method is to mount the SPD directly to the electrical panel. For Type 4X applications, use the supplied mounting feet to secure the device.

1.4 Directly Mounted to Electrical Panel with Conduit – Alternate Method

An alternate installation method involves using a short, straight conduit. Avoid 90° conduit elbows and keep the conduit run as short and straight as possible. Install the SPD as close as possible to the electrical panel. For Type 4X applications, use the supplied mounting feet to secure the device.

2. Wiring Installation

Refer to Section 3, Wiring Diagrams, and the applicable wiring schematic for your electrical system when wiring the SPD.

TURN OFF power to the electrical equipment connected to the SPD, following NEC, CEC, state, county, and local codes.

Eaton Innovative Technology SPDs have internal overcurrent protection and do not require an external overcurrent protection device (OCPD) unless mandated by NEC, UL, or local electrical requirements for conductor protection. NEC Article 310.15(B)(16) specifies OCPD ratings for conductors. For #10 AWG conductors at 60°C, a 1-pole (single phase), 2-pole (split-phase), or 3-pole (3-phase) 30A branch circuit breaker is typically required to protect SPD conductors.

Twist and bind SPD wires tightly together. Minimize overall lead length for optimal SPD performance. For phase wire length, aim for less than 14 inches (35 cm) twisted and bound. For wires longer than four inches, twist them once for every four inches of length to maximize performance.

If the SPD is configured for remote monitoring (model dependent), connect the Form C relay contact wiring to an alarm or building monitoring system. Refer to the document in Table 2 for Form C relay ratings. Note: Form C contact utilization is optional and not required for SPD operation.

4. Operation

4.1 Power Up and System Checkout

Tighten and recheck all connections and mounting before proceeding.

Switch main panel power to ON. Then, switch the SPD branch circuit breaker(s) to ON, if applicable. One LED should illuminate for each phase voltage being monitored. Single-phase systems will light one LED, split-phase systems two LEDs, and three-phase systems three LEDs.

If connected LEDs do not light, remove power, re-check connections, and test again. If LEDs remain unlit, contact your local authorized distributor or the Eaton Technical Resource Center, as the SPD may be damaged.

4.2 LED Color States

When properly installed, only green status LEDs should be energized. Refer to the document in Table 2 for more information on SPD LED color states.

5. Maintenance

Eaton Innovative Technology SPD devices are self-contained and require no maintenance or contain serviceable parts. If any LED changes state, the unit has lost surge protection and must be replaced. Contact your Innovative Technology Master Distributor or Eaton's Technical Resource Center for additional information and technical assistance, as the SPD may be under warranty.
