Description of Product
PDU (Power Distribution Unit)
230V: The PDU is designed to distribute 230Vac to appliances and
sockets throughout the habitation area of the caravan or motor home
via suitable protection devices.
The circuits are designed to customer specifications.
12V: The PDU is designed to distribute the 12Vdc power throughout
the habitation area of the caravan and motor home via relays and
fused circuits.
Installation of the PDU
Dimensions of the PDU.
Ventilation
The PDU requires a minimum surrounding clearance of 75mm around the
ventilation slots.
The PDU MUST be installed as such that external heat sources will not have a
detrimental effect on the normal operation of the unit.

Fixing of the PDU to a vertical or horizontal surface.
The PDU can be fixed to either a vertical or horizontal surface using
the fixing lugs located on the PDU (Fig 1 points A+B).
All four fixing points of A or B MUST be used to secure the PDU to
prevent damage to the unit from vibration.
The fixing lugs are mirrored on the opposite side of the PDU.
Access to connectors
The PDU should be installed in such a way that access to the
connectors at the rear of the PDU (Fig 3) are only accessible by the
use of a tool either by location or an enclosure securely fastened
behind the PDU.

Connection to the mains supply
Connection of the PDU to the mains supply* should be made by the
supplied connector (Fig 3 point A) enclosed in a suitable enclosure
accessible with use of a tool or by location accessible with the use of
a tool, connection can also be made by hard wiring to the supply
inlet**.
* Ensure the mains supply is switched off before connecting the PDU to the
mains
** Note all electrical work must be carried out by a competent person.
Storage of the PDU
The PDU MUST be stored in a dry storage area suitable for storing
electrical and electronic equipment.
Servicing of the PDU
The RCD and MCB’s should be checked at the annual service for
loose connections on the conductors and busbars.
The earth terminal should be checked at the annual service for loose
connections.
The fixing lugs on the casing should be checked for loose fixings and
damage at the annual service.
The 12V fuses should be checked for correct installation at the
annual service.

PCB Pin information
Currently there are two available PCB versions that can be installed
into the PDU unit, one has been designed for the use in caravans and
one has been designed for use in motorhomes.
PCB-268-MD (designed specifically for caravans)

PCB-269-MD (designed specifically for motor homes)

This circuit disconnected when the engine is running but is otherwise permanent.

****
when a positive feed is applied to this pin from the 12v ps sig when connected to mains it allows the
vehicle battery to be charged from the power supply.
*****
When using a dual stage power supply, the charging side must be fitted to CHG 1 and the power supply
output to CHG 2, when using a single stage power supply, the two tabs must be linked.
