PDU14

PART#: 212-2014-K2July 30th, 2019
Introduction
The Power Distribution Unit (PDU) is a compact and convenient point of load pow-
er distribution product for installed electrical devices. By using this device and
carefully planning the distribution of mobile equipment power feeds, complex inde-
pendent wire runs and unreliable fuse panel connections can be avoided.
Each circuit can be individually fused further reducing risk of damage to devices
from circuit overload. The PDU 14 unit provides constant and ignition outputs to
meet the typical vehicle and equipment requirements.
General Warning
1. The use of emergency warning devices does not ensure the safety of
the operator. The operator is responsible to ensure safe operation of
the vehicle regardless of whether the warning device is in operation or
not
2. The effectiveness of this or any warning device is highly dependent on
proper installation and maintenance. Read the manufactures instruc-
tions before installing and follow all recommendations.
3. When in use the operator must ensure that the warning signal is visible
and not obstructed by vehicle components (i.e. open trunk lid), people
or other obstructions
4. This device is intended for use by authorized personnel only The user
is responsibility to ensure that all local, state/provincial and federal
laws are being complied with. D&R assumes no liability for any loss
resulting from the use of this device.
5. The device must be installed so as not to reduce the output perfor-
mance of vehicle systems
6. Placement of control switches must be so as to provide convenient
reach for the operator without loosing eye contact with the road.
7. Emergency warning devices require high electrical voltages and/or
currents. Properly connect and ground all circuits. Shorting or improp-
er grounding of this device may caused personal injuring, vehicle
damage or both
8. All operators should be properly trained in the operation of this de-
vice to ensure both their and public safety

Installation and Mounting
1. Any device used inside a vehicle, may cause severe personal injury if not properly mounted
and secured. Objects used in the vehicle may become airborne during a collision or other
sudden changes in vehicle speed or direction, such as braking, acceleration or turns.
2. Be sure to mount unit through the steel of the vehicle. Avoid mounting through plastic or
other non-structural materials.
3. POINT OF INSTALLATION MUST NOT INTERFERE WITH DEPLOYMENT OF
VEHICLE AIR BAGS.
4. D&R Electronics recommends this or any of our products be installed by qualified pro-
fessionals.
Warning
Unpacking & Pre-Installation Check
D&R Electronics Co. advises that you open and examine all shipments within 48
hours of receipt. The Power Distribution Unit PDU is shipped pre-assembled
and factory tested. All necessary hardware for standard installation is included.
Remove all components from the shipping carton.
Use this pre-installation check list to verify your unit:
1. Confirm contents with the packing slip
2. Examine unit for damaged in transit (i.e. scratches, broken or bent connect-
ors. etc). Report any damage to the carrier immediately. Keep all shipping
material
3. The unit is factory tested and a pre-installation check is not needed.
Mounting the PDU unit
The PDU14 may be mounted anywhere inside the vehicle away from heat, mois-
ture or the elements.
1. Ensure that mounting location is flat and that device is secured to solid vehicle
body parts
To mount the PDU unit proceed as follows:
1. Determine an appropriate mounting location
2. Confirm there is adequate access and clearance for the wiring and its connec-
tions.
3. Secure the PDU with 4 self tapping mounting screws (not supplied).

Wiring and Setup Instructions
1. Looms, grommet, cable ties or other installation hardware should be used to
anchor and protect wires
2. All wire should conform to the minimum wire size as specified by the manu-
facturer.
3. Splices should be minimized and made in a fashion so as to protect from cor-
rosion to reduce loss of conductivity.
Warning
Note: The exact number of available connections varies by application, refer
to the specifications and typical output fusing combinations to ensure that the
safety and reliability of this product is not compromised.

PDU14 Input and Output Wiring Diagram for the following
detailed instructions
Wiring information:
Red 6 AWG - this is the Battery Input for the PDU
Black 6 AWG - this is the Battery return for the PDU
Blue 10 AWG - this is the high current output
Black 10AWG - this is the high current output return

PART#: 212-2014-K6July 30th, 2019
1. Run a 6 AWG wire lead from the Battery via a fusible link or circuit breaker rated at
80A to the PDU14.
2. Cut to length and slide one of the provided grommets over the wire (Figure 3.)
3. Strip 1/2” length of insulation from the end of the wire, insert the bare wire into the pin
connector , crimp or solder.
4. Insert pin and wire into the Red connector housing until it “snaps” into place, pay atten-
tion to the orientation of the pin when inserting it into the housing see Figure 3.
5. Slide the grommet down the wire into the plug to seal connection (Figure 4).
6. Connect the Red plug on to the battery input “+12V IN” power claw clip of the PDU14.
Connecting ground input to the PDU
1. Run a 6 AWG wire lead to the chassis of the vehicle, if necessary run this wire directly
to the battery negative terminal if a good low resistance chassis connection is not availa-
ble
2. Prepare and the 6 AWG Ground wire for connection to the PDU using the same proce-
dure as the battery input wire (Figures 3 & 4) and insert the finished pin, wire, and
grommet combination into he remaining black housing.
3. Connect the plug to the “GND” Input power claw clip next to the “+12V IN” plug
(Figure 3).
Connecting +12V OUT from the PDU
The PDU supplies a single high current output which may be used to power a high current
device such as a light-bar, this output uses the same style of power connector as the input
wire from the battery:
1. Run the wire from device (i.e. light and siren controller) to the PDU mounting location.
Using the same process for the Battery input wire (steps 2 and 3) prepare the wire for
insertion into the BLUE pin housing.
2. Insert the wire and pin combination into the Blue housing until it “snaps” into place,
slide the grommet down the wire into the plug to seal connection (Figures 3 & 4).
3. Connect the Blue plug onto “+12V OUT” power claw clip (Figure 1).

PART#: 212-2014-K7 July 30th, 2019
Connecting the ground output (GND) from the PDU
This output ground connection is the return path for the device connected to the +12V Power
from the PDU.
1. Run the ground wire from device (i.e. light and siren controller) to the PDU mounting
location.
2. Prepare the wire in the same manner as the “+12V OUT” and insert the wire, pin and
grommet combination into the black housing.
3. Connect the Black “GND” plug to the power claw clip next to the +12V OUT plug.
All other connections from the PDU are made via the terminals on the chassis. These
terminal connections should be made using good industry practice ensuring no loose or
frayed wire be present at each screw-down terminal. We further recommend using a good
quality crimping tool and wire terminals to secure the wire and provide a solid
screw-down connection at the terminal block.
Application Brief
The connections and fusing configurations are installation specific and should be planned out
by the installer.
The following charts indicate some typical output connections and fusing options, that ensure
the PDU operates within the designed maximum specifications.
Table 1 shows some of the possible combinations when only one area of output (Ignition OR
12V Battery) is used.

PART#: 212-2014-K8July 30th, 2019
Table 2 shows some of the possible combinations when both outputs are used at the same time
(Ignition AND 12V Battery).
