Engine Shutdown Add-On Kit

(445.18(B))

Introduction

New specifications in Article 445.18(B) of the 2017

National Electrical Code (NEC) require generators to be

equipped with an independent means of shutting down

the prime mover (engine). The shutdown mechanism,

when activated, requires a mechanical reset. Generators

15 kW and larger require an additional means of

shutdown to be installed outside the generator enclosure.

This kit includes all components needed to install

required engine stop switch(es) on Generac air-cooled

optional standby generators equipped with Evolution 1.0

and 2.0 or Sync™ version 2.0 and 3.0 controllers.

NOTE: Verify controller version and identify correct

installation instructions before proceeding. Failure to do

so will result in improper installation and controller

damage.

Installation Overview

The basic steps for installing this unit are:

1. Drill mounting hole(s) for switch(es).

2. Install switch(es).

3. Connect switch wiring to controller harness.

4. Start generator and test switch functionality.

Required Tools

The installer must be equipped with common installation

tools such as a power drill, drill bits, center punch, wire

cutters, wire stripper, crimper, pencil or marker, and

electrical tape. Other tools required for this installation

are:

• Step drill capable of boring a 13/16 inch (21 mm)

diameter hole

• Clear silicone sealant

Prepare for Installation

Before installing this kit, prevent the generator from

accidental startup:

1. Lift lid and turn the generator OFF.

2. Remove 7.5 A fuse.

3. Remove intake end panel.

4. Disconnect negative battery cable.

5. Remove controller fascia.

DANGER

Accidental start-up. Disconnect power and render

unit inoperable before performing service work.

Failure to do so will result in death or serious injury.

Controller Identification See Figure 1 to determine if generator is equipped with (A) an Evolution 1.0 (Sync 2.0) controller, or (B) an Evolution 2.0 (Sync 3.0) controller. 2.0 Install Wiring—Evolution 2.0 (Sync 3.0) Controller Two extension wires for the engine shutdown switch are already installed in the wiring harness in generators equipped with the Evolution 2.0 (Sync 3.0) controller. Therefore, the extension wires included in the engine shutdown kit are not used. 1. Remove controller. 2.

Rear Panel Installation 1. Divider Panel Installation See Figure 4. Measure 1.5 in. (3.81 cm) down from top edge of rear panel and 3 in. (7.6 cm) from left edge of rear panel. Mark an X at this location. This will be the center point for the switch mounting hole. x 1. See Figure 6. Measure 2 in. (5.1 cm) down from underside of flange at top of divider panel. Measure 5 in. (12.7 cm) inward from front face of divider panel. Mark an X at this location.

Switch Wiring Installation Dual Switch Wiring Switch(es) must be connected to the wire leads added to the J2 wiring harness connector. If two switches are installed, the switches must be wired in series with each other. (rear panel and divider panel) 1. Single Switch Wiring 2. (rear panel) 1. 2. 3. 4. 5. 6. 7. 8. 3. Cut two lengths of 18 AWG wire at 18 in. (46 cm). Strip 3/8 in. (10 mm) of insulation from ends of both wires. Crimp an insulated quick disconnect connector to one end of each wire.

Firmware Update—Evolution 1.0 (if required) The generator controller may require a firmware update. For EcoGen™ and Synergy™ generators, firmware version 1.14 or higher is required. For all other generators with Evolution or Sync 2.0 controllers, version 1.18 or higher is required. Verify controller firmware version. If an update is required, install latest version before testing engine shutdown switch(es). 1. With generator controller OFF, enter Edit menu. 2.
