Section 3 Installation and Operation

Mounting and Grounding

DANGER
Loss of life. Property damage. Installation must always
comply with applicable codes, standards, laws and
regulations. Failure to do so will result in death
or serious injury.
WARNING
Equipment damage. Only qualified service personnel may
install, operate, and maintain this equipment. Failure to
follow proper installation requirements could result in death,
serious injury, and equipment or property damage.
See Figure 2-2 items J and K. For proper installation the
sheet metal opening must be 272.1 x 240.0 mm with 25.4
mm keep-out zone for cabling purposes.
IMPORTANT NOTE: Verify there is at least 60 mm of
space behind the controller for proper ventilation.
See Figure 3-1. The Main Controller is mounted to the
enclosure through a rectangular opening in the sheet
metal and secured by eight M4-8 mm screws and eight
#8-M4 lock washers (part no. 022264) around the edge
(A). Tighten screws to 6.6 in-lbs (0.75 Nm). The gasket
(C) and screws help prevent water from entering the
module.
To provide proper grounding, use a ground wire and
connect it to the Main Controller via a ring terminal. Use
the self-tapping grounding screws (B) on either ground
tab located on the bottom edge of the diecasting
enclosure.
IMPORTANT NOTE: Care should be taken when
tightening hardware. If excessive torque is applied,
permanent damage may result. If not enough torque
is applied, water may enter the panel and cause
damage.

Cleaning

Do not use any cleaning solution to clean the Controller
enclosure or cover. Clean with damp cloth or sponge.
The Controller contains electronics circuitry. Use extra
caution not to drip water inside the Controller when
cleaning it around the vent and other holes. If water or
other liquid enters the Controller, disconnect power until
(000190)
the Controller dries out completely. Special care should
be taken when cleaning the touch screen. Dust off hard
particles on the touch screen and use touch screen wipes
to clean it.

Connections

(000182a)

Power Supply

The power for the Main Controller normally comes from
the engine battery, either 12 or 24 V
fused with a 5 A Time Delay Fuse. The Main Controller
has reverse battery protection in case of miswiring. The
Main Controller can operate from any voltage supply in
the range 6-35 V
for this connection.

Connectivity Server Wiring

Normally the Main Controller will be connected to a
Generac supplied Connectivity Server. The Main
Controller provides a regulated 12 V
the server.

Module CAN Bus Interface

There is a dedicated CAN bus port for connection to
Generac's peripheral control modules. Examples of
these modules include the Governor, AVR, and Battery
Charger. A shielded twisted pair cable should run from
the Main Controller to the first module. The rest of the
modules are wired using shielded twisted pair cables in a
chained fashion. Each end of the CAN bus must be
terminated with appropriate resistors. See
RS-485 Termination

ECU CAN J1939 Interface

A
There is a dedicated CAN bus port for connection to
J1939 compatible devices such as an Engine Control
Unit. The particular interface method for a given J1939
module is selected via the Main Controller configuration
C
settings. A single shielded twisted pair cable should run
from the Main Controller to the ECU. The shield should

be connected at the Main Controller end only. Each end
of the CAN bus must be terminated with appropriate
