Accessory 11BG
for Series 300
Installation
Accessory 11BG module includes a programmable engine–
generator exerciser and power source availabil ity contacts. It
can be added to a Series 300 Automatic Transfer Switch (ATS)
that has a Group 1 Controller. If an existing engine exerciser
(Acc. 11CD) is already installed, it must be disconnected first.
TheAccessory11BGmodulemountsdirectlybehindthe
Series 300 ATS opera tor interface on the inside of the
enclosure door. The module connects to the Series 300 ATS
operator interface board and Group 1 controller.
Kits K629830 & K749999 include the Acc. 11BG module,
mounting hardware, and all necessary wiring.
Tools 1/4”, 5/16” nutdrivers, small blade screwdriver
required: your Series 300 ATS Operator’s Manual
for setting the DIP switches
ELECTROCUTION – FLASH HAZARD
Do not work on the transfer switch until
both the utility and generator are off.
Turn OFF both circuit breakers.

Module Installation –Figures2&3
1. With all power OFF, open the enclosure door. Locate
the operator interface (membrane controls) mounted
on the inside of the enclosure door. Use a 5/16”
nutdriver to remove (counterclockwise) the four hex
nuts from the corners of the operator interface. Do not
remove the operator interface board (Figures 2 & 3).
2. Install (clockwise) four standoffs (from the kit) onto
the four studs and tighten them with a 1/4” nutdriver.
3. Install the Acc. 11BG module on top of the operator
interface so that four standoffs fit through the corner
holes. Then install (clockwise)four 6–32 hex nuts (from
thekit)tosecuretheassembly.Tightenthenuts.

Step 1
Connecting the Module – Figures 1, 2, 4
1. With all power OFF, locate the two ribbon cables and
note direction and orientation of each cable.
2. Unplug the ribbon cable (coming from the Controller)
from the operator interface (J3 lower right side) and
reconnect it (same orientation) to the Acc. 11BG module
(J1 lower right side). See Figures 1, 2, & 4.
3. Connect the new ribbon cable (coming from the Acc.
11BG module upper right side) to the operator interface
(J3 lower right side) with the same orientation as the
original cable that was moved. See Figures 2 & 4.
4. Strip the insulation from both ends of the #16 gauge
white wire (from the kit). Connect this prepared wire
between A c c . 11BG module terminal 9 (right side) and
the Group 1 Controller terminal 4 (bottom left). Figure 4.

includes power source availability signal contacts and a programmable engine exerciser.
Power Source Availability Signal Contacts
ThemoduleprovidesoneFormCcontacteachforthe
normal and emergency power sources to signal the
acceptability of the source as sensed by the controller. The
signal contacts operate in conjunction with the Source
Available lights on the operator interface. Field wiring
terminals are provided as shown in Figure 5 and the wiring
diagram.
Contact ratings:
2 amps @ 30 Vdc, 0.5 amp. @ 125 Vac resistive

Programmable Engine–Generator Exerciser
Note: Refer to your Series 300 ATS Operator’s Manual
to set DIP switches S1 & S2 in the Group 1 Controller.
A backup battery
(see Operator’s Manual, Sections 4 and 5) must be turned
on to maintain the settings and to allow programming with
the normal and emergency power sources turned off.
TheAcc.11BGmoduleincludesaprogrammablegenerator exerciser that provides for weekly or biweekly operation. The exerciser may have to be turned on (enabled) by
setting S1 DIP switch actuator 7 to OFF (left position), and
S2 DIP switch actuator 5 to OFF (left position).
The programmable engine–generator exerciser incorporates a 7–day or 14–day time base. Proper Group 1
Controller settings must be made to determine whether or
not the test will be done with or without load transfer
(S1 DIP switch actuator 8).
