AP2003 / AX2002
Standard Power Supply / AEbus extender
GENERAL
Power supply and AEbus extender base unit. Input 230 VAC, output 27VDC/ 1.3A short circuit
protected to supply several AEpacks. (Power output identical to AP2001)
As there is no additional intelligence on board (inputs, monitoring, battery status) the AP2003 has no
address switch. If those functions are needed the AP2001 must be chosen.
AX2002 can be added in AP2003 for extending AEbus to AEpacks at distance more than 5 meter (up
to total bus length of 300 meters)
AEpacks are hot-swappable, so changing AEpacks or connections can
be done without interrupting the other AEpacks connected on the AEpu.
All connections are underneath the covers of the AEpack. Topcover
must be left in place, bottomcover can be lift off straight up.
On top: Connections for AEbus
On bottom: Connections to peripherials
Remark: The AX2002 is not hot-swappable, always disconnect power!
AEbus CONNECTIONS
AEbus connections: point to point to identical connector point of
each AEpack. The AEbus connector has two rows, which enables
easy coupling of more AEpacks.
Going outside AEpacks housing: shielded cable must be used;
CH and CL must be one twisted pair. From other pair one cable
is used for GND. Shield must be connected to metal housing, to
which also the metal mounting rail of the AEpacks is connected.
AEpacks at larger distance use the AEbus extender (AX2002) on
the power supply.

AP2003 / AX2002
SAFETY PRECAUTIONS
Following safety precautions must be observed during normal use, service and repair:
• Always disconnect AC mains- and DC (emergency) supply before adding or replacing the
AX2002.
• The AP2003 must be connected with safety ground (GND to metal case to which also the
metal mounting rail of the AEpack is connected). If no metal housing is used, the mounting
rail must be connected with safety ground.
• Always disconnect from mains power supply before removing one of the covers
• The AP2003 may only be installed and serviced by qualified personnel
• To be sure of safety, do not modify or add anything to the AEpacks other than mentioned in
this installation guide or indicated by NEDAP N.V.
• If the main fuse is blown, it is essential first to find the cause and make repairs before
replacing the fuse.
• Replace fuses only with the same type and rating.

AP2003 / AX2002
TYPICAL CONFIGURATION
AEpacks can be connected to the AP2003 (AP2001) for the supply of power and communication bus
(extended AEbus). Also an AP8001 (AEpu) is needed for data handling and connection to the
AEserver.
All AEpacks are connected to each other using the AEbus with the interlinking connector at the upper
side of each AEpack.

CALCULATION MODEL MAXIMUM POWERLOAD
More than one AEpack can be connected to the power AEpack. For the calculation of the total power
consumption add the internal power
consumption of each individual AEpack
and the load it’s load from external
devices (e.g. lock).
Door and
antenna
With the diagram beside the total load
for an AP2001 can be calculated. If the
total load exceeds the 1.3A an extra
AP2001 must be added.
The used AEpacks are in italic. For the
12VDC output a correction factor of 0,65
is used to get the correct load for 27VDC
(AEbus power).
In this example total load is 2230mA, so
two AP2001’s (AP2003’s) are needed.

USING MORE THAN ONE POWER SUPPLY
If more than one power AEpack is needed (and AEbus is not longer than 5 meters, otherwise AX2002
must be used), connect only CH, CL and GND signals to AEbus connector (don’t connect VIN and
GND). CH and CL must be one twisted pair. From other pair one cable is used for GND.
EXTENDED AEBUS: AX2002 (optional)
If the AEbus exceeds 5 meters, the AX2002 board must be installed in the AP2001 on both sides (see
also above figure). The total length of the AEbus if AX2002’s are used is 300 meters. Installation of
the AX2002 will be at factory. In those case where the AX2002 must be installed in the AP2001
always take care of the safety precautions.
Attention: set switch at backside of the AX2002 to the correct position: Switch selects terminating
resistor needed for correct communication:
First and last AX2002 of the extended AEbus: switch to IN-side (towards connector)
All other AX2002’s: switch to OUT-side
Remark: AX2002’s must always be connected to other AX2002’s, so never to the AEbus connector.

EXTENDED AEBUS CONNECTIONS (AX2002)
The connector for the extended AEbus is
located above the AEbus connector. Only the
communication is extended, not the power
supply (this is achieved from the Power AEpack
on which the AX2002 is installed).
Using 2 x 2 x 0,50 mm² shielded cable means
that CH and CL must be one twisted pair.
From the other pair only one cable is connected
to GND. The cable shield must be connected to
the housing of the AEbox.
