PLEASE READ THOROUGHLY BEFORE INSTALLING
DO NOT ATTEMPT
INSTALLATION OF THE X-PORT UNLESS
YOU HAVE BASIC AUTO-ELECTRICAL KNOWLEDGE!
NO LIABILITY CAN BE ACCEPTED BY THE
COMPANY FOR DAMAGE CAUSED BY INCORRECT INSTALLATION.
The X-PORT is only suitable for electrical systems with
negative earth return in the range of either 12 volt or 24 volt systems.
PLEASE ENSURE THAT THE
SYSTEM FOR INSTALLATION IS OF THIS TYPE.
As the power input and output studs are brass studs care must
be taken during installation that undue force is not applied which would snap the studding.
The input/output studs must not be used as a termination point for any high current connection
any additional connections should be made at the battery terminals or separate connection points.
Disconnect Battery negative
(-) leads first, followed by the positive (+) lead. (This is to prevent
accidental damage by shorting positive lead to earth return).
Locate a suitable position for X-PORT and fit securely. Choose a position near
to the charging source which affords protection from
extremes of heat and ingress of oil and water. Ensure there is a free flow of
air around and under the unit.
The 0 volt (negative) should be connected directly to known good 0 volt (negative) connection.
For battery sensed energised alternators connect an ignition feed to the M4 'SENSE' terminals via a 5amp
fuse for each alternator system.
Where the alternators are operated from a single engine the sense terminals can be connected to
the same source but via separate fuses. On dual engine/alternator systems the ignition feeds
must be from their retrospective ignition systems. Failing to fuse this ignition feed may destroy
the internal diode associated with the sense circuit and will make the warranty void.
Where only one alternator is used and a separate charging system i.e. wind generator is
connected to the second input ensure that the correct inputs are terminated to each input.
Connect the Outputs OP1 & OP2 and where fitted OP3 to separate battery banks.
NOTE. Ensure all current carrying cables are of sufficient capacity and all terminations are
made with copper tube terminals of the correct cable and crimp size.
Connect the inputs IP1 & IP2 to the charging sources (i.e. alternator) outputs. In most installations
these should be the only cables connected to the input studs.However where a single output battery
charger is being used to maintain the charge to the battery banks whilst the alternator is
not being used it can also be connected to the input on a single input unit or either input on
a two input unit providing it's output does not exceed the rating of the X-Port. If a multiple output battery
charger is being used the outputs of the battery charger
can either be connected to the retrospective X-Port output terminals or to each battery bank direct.
CHECK THAT ALL WIRING CONNECTIONS ARE CORRECT, AND TIGHT.
Re-connect batteries.
Commence charging, ensuring that the X-PORT green led is illuminated for each input. (Two led's on 2 + 2 & 2 + 3 models).
IF LED IS NOT ON, SWITCH OFF IMMEDIATELY AND RE-CHECK ALL CONNECTIONS.
