1-Mounting Kit
WARNING: During installation, disconnect the battery cables. When disconnecting the battery always
remove the Negative cable first and install it last.
OPERATION
The Power Grid Power Module contains four channels of programmable 20 Ampere solid state relays.
Each output can be controlled independently, or simultaneously, giving great flexibility. Each channel
can use Time, Engine Speed, or a Temperature sensor to activate fans, fuel pumps, or NOS systems.
The Power Grid's data logger within the PN7730 can record all functions of the Power Module.
All four outputs of the Power Module have the identical properties and features.
WIRING
Power Grid
When using the Power Module (PN7764)
with the Power Grid (PN7730), connect
to the Power Grid via the CAN connector.
This increases control options over the
outputs and utilizes the Data Recorder.
Stand Alone
In stand alone mode, a separate pigtail
is offered that will connect to the MSD
CAN-BUS pigtail for the 12V and Ground
required to enable solid state relays.
A Loctite® Threadlocker 242® packet
is included to fasten the threaded screw
for the main power feed.
Apply a small amount of the Loctite
242. It will penetrate the thread grooves,
and bond within 10 minutes. Do not
apply too much Loctite, applying too
much can insulate the wire and cause
problems.
The medium strength bond can be
broken with hand tools, if necessary.
