Satellite Data Modem (SDM) Installation
Installing Mounting Bolts
Vehicles Without Airdams
• On a vehicle without an airdam and/or the mount is on the rear of the cab, orient the SDM
so the SDM cable connection faces toward the
side
of the vehicle. See page
for
cable routing examples.
• This orientation prevents wind-driven rain from pounding the connector, while preventing
trailer swing from hitting the connector.
• Install the SDM so that it does not exceed the Federal D.O.T. mandated maximum legal
height of 13’ 6".
Installing Mounting Bolts
1.
Mount the SDM to the mounting bracket using the bolts and washers supplied with the
SDM mounting hardware (or exact substitutions). Normally, bolts longer than
3/4
"
should not be used. If longer bolts are needed, such as when the SDM is being
attached to a fiberglass shelf with a plywood base, use
1/4
-20 UNC grade 8 or better.
2.
Tighten the SDM mounting bolts to the recommended torque of 72
inch
/pounds.
Caution
To avoid over-torquing,
never
use power tools to tighten mounting hardware.
