Installation 6-5MTX5000 User and Technical Manual
CAUTION
Be sure the power being supplied matches
the power required by the equipment.
CAUTION
Power supply cords and cables must be
protected. Do not run cords where they can
be walked upon. Protect cables against
pinching and chafing. Pay special attention
to locations where the cables enter or exit an
enclosure or make a sharp bend.
CAUTION
Ensure that the electrical supply is protected
by overcurrent protection devices as required
by the applicable electrical codes.
6.7 Grounding
CAUTION
Be sure the equipment grounding follows
applicable electrical codes.
CAUTION
Never modify a grounded power plug to
connect to an ungrounded receptacle.
• The MTX5000 must be connected to the common ground
on the installation. This common ground is often the
vehicle ground.
• The ground wire should be as short as possible, and follow
the straightest path possible.
6.8 Defining the Wiring Harness
This section describes how to define the wiring harness that
connects the MTX5000 IDU to ODU. The wiring harness
contains RF/Power cables and function cables.
Supplying main power to the MTX5000 IDU is covered in
Section 6.6 on page 6-4.
6.8.1 Steps to Define the Harness
Perform the following steps to define the wiring harness between
the IDU and the ODU.
1. Select the type of RF/power cabling required. See
”Select the Type of RF/Power Cabling” .
2. Select the function cables required. See Section 6.8.3
on page 6-7.
3. Determine the size of the wiring harness required.
See Section 6.8.4 on page 6-9.
4. When the wiring harness is fabricated, go to “Installing
the Fabricated Harness” on page 6-13.
6.8.2 Select the Type of RF/Power Cabling
The first step is to determine what type of RF and DC power
cabling you will be using to connect the IDU to the ODU. There
are three different options:
• Triax connectors (RF, control, and DC power in one
cable). See Figure 6-3 on page 6-6.
• Type “N” connectors (RF and control on one cable, DC
power in another cable). See Figure 6-4 on page 6-7.
• TNC connectors (RF and control in one cable, DC power
in another cable). See Figure 6-4 on page 6-7.
