manual.
Note: Always follow basic safety information when using electrical
devices to protect against electric shock, fire hazards or injury.
1.1 General safety
• Only use the PDH as intended
• The device must not be used if itself or the battery connection
cable is visibly damaged in any way shape or form.
• This device may only be repaired by a qualified and authorised
person. Failure to adhere to this direction could cause harm and will
void product warranty.
• Always keep and use device out of reach of children.

3. Getting Started (introduction of the device)
3.1 Fitting the PDH
• Choose a location that is easily accessible with adequate
ventilation.
• Ensure the location you have chosen to install your PDH is free of
potential risks that may damage the device i.e. splashing water,
venting gases, naked flames or potential combustible gases or
liquids.
• Make sure there is enough room to connect power input and
accessories.

3.2 Connecting the PDH to battery
Using a 50A fuse is a MUST and should be considered on any
installation.
You can connect your PDH to your battery using an
Anderson style connector. Please ensure a 50A fuse is fitted
inline on the Positive cable as close to the battery as possible, it is
highly recommended to use wiring no less than 8AWG. (50A fuse not
included)
With the Negative cable, we suggest using a negative
busbar as illustrated inline with this connection before returning to
the battery. (Busbar not included)
Ensure all connections to the battery are tight and secure
and plug the power to the top Anderson style connector on the PDH
labelled “INPUT”.
HANDY HINT - Using a negative busbar will prevent the need of
returning all your negative lines from your devices controlled by the
4 x Relay outputs back to the battery and provide a common ground
for these devices.

4. Features and Specifications
4.1 Features – Protection Modes
The PDH incorporates 3 protection modes to keep the device
and the battery it is connected to safe.
• Voltage Protection Mode
• Current Protection Mode
• Temperature Protection Mode
Voltage Protection mode:
Voltage protection mode is incorporated into the PDH to
protect the battery from draining past certain points based on the
selected settings by the user.
Voltage Cut Out Settings:
• High: 12.1v – When the device is in High Mode the letter “H” will be
displayed in the top left-hand corner of the PDH screen
• Medium: 11.6v - When the device is in Medium Mode the letter “M”
will be displayed in the top left-hand corner of the PDH screen
• Low: 10.9v - When the device is in Low Mode the letter “L” will be
displayed in the top left-hand corner of the PDH screen
• No: No Protection – (No cut out point). When the device is in No
Mode the letter “N” will be displayed in the top left-hand corner of
the PDH screen.
“N” Setting will not offer any voltage protection. This mode is
to be used in circumstances where the battery must be pushed to its
absolute limits. Using “N” setting runs the risk of permanent damage
to the battery because it will allow the user to use the battery to the
last volt. When “N” mode is activated by the user, the device will start
an override timer for “N” mode. This timer lasts 15 minutes.
After 15 Minutes the device will then override to medium settings.
Voltage Protection Reset:
If Voltage Protection is triggered the device will wait
4 minutes before re-checking the battery voltage state.
Voltage protection will override at the following voltage:
• High: 12.6v
• Medium: 12.2v
• Low: 12.0v
If Device is turned off, it will remember which voltage setting
it was previously in and automatically be set to that setting unless in
“N” mode.
If the device is turned off in “N” mode, when turned back on it
will restart in “M” settings.
