HRN-BD16K1 and HRN-RS12K1 Fleet Management
The HRN-BD16S1 and HRN-RS12S1 are specifically intended for vehicles that have
a main power battery disconnect switch on the +12/24V, and are using the
T-Harness. Do not use this harness for Ground switched battery disconnects,
or the HRN-CW03K4 and HRN-RW04S4 harness.
Successful installation of any device or equipment requires knowledge of the
installation and device requirements.
This information is obtained by reading the device documentation and by
speaking with the customer to understand their requirements.
Installations should never be performed without first reviewing and
understanding the device documentation and customer requirements.
Note: The main power switch may disconnect the negative or the positive
battery terminal.
NOTICE: Never assume polarity, and never assume that all vehicles are
identically wired.
NOTICE: Connections at these main-power disconnect switches are often
exposed and must be properly protected from corrosion. We recommend you use
loom to protect cable runs, as well as dielectric grease, heat shrink, and
self- fusing tape at connections. Any direct-to-battery connections also
require wire and corrosion protection.
WARNING! It is important to understand the risks involved when bypassing
a main-power switch. Improper grounding, lack of grounding, or improper fusing
can lead to death or serious personal injury. The bypass must not
inadvertently provide an alternate path for other vehicle circuits to power.
The client must be informed and involved so that they understand and can
approve the installation.
-
Confirm vehicle main power switch is + positive switched.
This is done by metering between the positive (J1939) pin and the chassis, and toggling the main power switch. If the vehicle is ground switched, the HRN- BD16S1 and HRN-RS12S1 cannot be used.
-
2a) Connect the T-Harness 16 pin connector to the plug side of the HRN-BD16S1.
2b) Connect the T-Harness 12 – way Amphenol weather resistant connector to the plug side of the HRN-RS12S1. -
Ensure it is securely seated and use a cable tie to hold the connectors from separating.
-
4a) Connect the GO device to the receptacle side of the HRN-BD16S1.
4b) Connect the GO RUGGED to the receptacle side of the HRN- RS12S1.
-
5a) Ensure it is securely seated and use a cable tie to hold the connectors from separating.
5b) Ensure all connectors are securely locked to hold the connectors from separating. -
Run the red power wire from the HRN-BD16S1 or HRN-RS12S1 to the battery and install the fuse holder. Any extension to this cable must be done with no smaller than 18AWG wire. Ensure passage through the firewall is grommeted, and the wire run is free of heat sources or sharp edges that could damage the loom/wire.
-
Locate the positive terminal of the battery. Make the connection between the positive terminal and the supplied (5A) fuse, ensuring the connections are corrosion protected. Fuse must be within 6” (150mm) of the terminal. Connect the red wire from the HRN-BD16S1 or HRN-RS12S1 to this fused connection to the battery.
-
Ensure the power wire (red wire) is secured with cable ties, and loomed.
-
9a) Secure the HRN-BD16S1, GO Device and T-Harness (within the cab, ideally behind the dash) ensuring all are secured and have a solid mounting to the vehicle.
9b) Secure the HRN-RS12S1, GO RUGGED, and T-Harness ensuring all are secure and have solid mounting to the vehicle.
Important Safety Information and Limitations of Use
WARNING! Do not attempt to install, configure, or remove any product from
any vehicle while the vehicle is in motion or otherwise in operation. All
installations, configurations, or removals must only be performed in securely
parked, stationary vehicles. Attempting to service moving or operating
vehicles could result in malfunctions or accidents, leading to death or
serious personal injury.
WARNING! All in-vehicle devices and related cabling must be securely
fastened and kept clear of all vehicle controls, including gas, brake and
clutch pedals. To ensure all devices and cabling remain securely attached,
inspect devices and cabling on a regular basis. Loose cabling or devices may
impede the use of vehicle controls, resulting in unanticipated acceleration,
braking, or other loss of vehicle control, which could lead to death or
serious personal injury. Upon sudden acceleration or deceleration, improperly
fastened, in-vehicle devices may detach and impact operators, which may lead
to death or serious personal injury.
WARNING! After an in-vehicle device is installed, if at any point a
warning lights up on the vehicle dash, or the vehicle stalls, or has a marked
drop in performance: shut off the engine, remove the device, and contact your
reseller. Continuing to operate a vehicle with these symptoms can cause loss
of vehicle control, leading to death or serious personal injury.
WARNING! Your in-vehicle devices must be kept clear of debris, water, and
other environmental contaminants. Failure to do so may result in the
malfunction or short-circuiting of units which can cause fire hazards or
vehicle damage, leading to death or serious personal injury.
WARNING! Do not attempt to remove devices from vehicles where they are
originally installed and then install them in other vehicles. Not all vehicles
share compatibility, and reinstalling devices in other vehicles may result in
unexpected interactions. This could include abrupt power loss, vehicle engine
shutdown while in operation, or poor or erratic vehicle operation, leading to
death or serious personal injury and/or vehicle damage.
NOTICE: This product does not contain any user-serviceable parts.
Configuration, servicing, and repairs must only be made by an authorized
reseller or installer. Unauthorized servicing of these products will void your
product warranty.
