Generac Power Systems G0089350 Feuille D'instructions

2023 NEC Engine Shutdown Add-On
Kit
Model G0089350
Intended for Air-Cooled Generators
Introduction
Currently, Generac air-cooled standby generators are
equipped with means to disconnect the unit from utility
power and generator emergency shutdown switches
which comply fully with the requirements of the NEC (up
to and through the 2023 NEC).
However, an increasing number of jurisdictions (AHJs)
are requiring the installation of an additional generator
emergency shutdown switch which is remote from the
generator and located/grouped close to the electrical
service disconnecting means - for quick access by first
responders.
The enclosed kit and these instructions are designed to
fully comply with all of requirements of the NEC, including
the most current 2023 NEC article 445.19 (A), (B), and
(C). The remote emergency stop switch shall be labeled
Generator Emergency Shutdown, and the label shall
meet the requirements of 110.21(B). Additional labels can
be purchased through
A0003172874.

(generator disconnect) to OFF (OPEN).
3. Remove 7.5A fuse from control panel.
4. Disconnect negative (-) battery cable.
5. Remove intake end panel.
6. Remove controller fascia.
7. Remove customer electrical connection panel.
Installing Relay Switch Kit
Proceed as follows to install relay switch kit:
1. Locate unused ground stud in the customer electri-
cal connection area, and mount relay switch kit us-
#
ing provided nut.
2. Locate 194 wire on relay switch kit. Route 194 wire
through customer connection panel grommet.
3. Place 194 wire onto TB1 terminal block in open
slot. Ferrule should be able to push into terminal
block without additional tools.
NOTE: Use a screwdriver to push tab open to place
194 wire if it is difficult to connect to TB1 terminal.
4. Locate 395A wire running between two existing
emergency shutdown switches installed on unit.
5. Cut 395A wire near the middle of the wire run and
strip each wire end ¼ inch.
6. Connect relay switch kit terminal blocks labeled
SW_A and SW_B onto spliced 395A wires.
7. Pull on lever, insert wire, and close lever to attach
terminal blocks securely.
8. Route SW_RMT wire through customer connection
panel grommet. Attach one side of remote switch
wires to SW_RMT and second wire to TB1 in the lo-
cation labeled 0 (ground).
9. If installing using TC-ER-JP cable, locate 395A wire
and connect it to terminal block from relay switch kit
