3. Installation
Installation of the SC-12 system requires both physical installation of the boxes
and communications cabling.
3.1 Preparing the installation
Check that the following are ready before getting started:
➢
Select mounting locations for each SC-12 component.
➢
Plan routes for communications cables from each box to closest hub box.
➢ Plan routes for +12V power to each of the hubs and driver output boxes
.
Follow these precautions during installation:
➢
Do not connect power to the any of the hubs or other system devices until all other
connections have been made.
➢
If a partial installation is made, some devices may be inoperable or may not operate as
expected.
Cable lengths are important in order to maintain the specifications of the CAN
communications bus used by the SC-12 system. Intermittent communications
problems may arise if the following specifications are exceeded:
➢
Maximum length between a Hub and any device: 5 meters.
➢
Maximum length between Front Hub and Rear Hub: 20 meters.
Select mounting locations and cable routes so that the above cabling
specifications can be met.
3.2 Physical Installation
Mounting mechanisms for most devices are one of the following:
➢
1/4” bolt mount (typically used with Master Control boxes and Switch Boxes)
➢
Flange mount
➢
DIN rail mount.
Other custom mount requests can also be arranged at time of order.
Bolt mounts should use only 3/4” long 1/4-20 bolts, which are provided with the
boxes. Deeper bolts may contact internal electronics and cause permanent
damage.
DIN rails use the industry standard EN 50022 - Top Hat Rail 35 × 15 type.
Once the mounting locations have been selected, physically mount the boxes to
their mounting locations on the truck.
➢
Make the appropriate connections to the Core Skipper box using the wiring diagram
