Electrical installation - external fan supply
Torque 0,5-0,6 Nm
Screwsize: M3
Only for IP54 units in the powerrange AKD 5016-5062,
380-500 V and AKD 5008-5027, 200-240 V AC. If
the drive is supplied by the DC bus (loadsharing), the
internal fans are not supplied with AC power. In this
case they must be supplied with an external AC supply.
Electrical installation - bus connection
The serial bus connection in accordance with the RS
485 (2-conductor) norm is connected to terminals
68/69 of the frequency converter (signals P and N).
Signal P is the positive potential (TX+,RX+), while
signal N is the negative potential (TX-,RX-).
If more than one frequency converter is to be connected
to a given master, use parallel connections.
In order to avoid potential equalizing currents in the
screen, the cable screen can be earthed via terminal
61, which is connected to the frame via an RC-link.
Bus termination
The bus must be terminated by a resistor network
at both ends. For this purpose, set switches 2
and 3 on the control card for "ON".

AKD 5000
DIP Switches 1-4
The dipswitch is located on the control card.
It is used for serial communication, terminals 68 and 69.
The switching position shown is the factory setting.
Switch 1 has no function.
Switches 2 and 3 are used for terminating an RS
485 interface, serial communication.
Switch 4 is used for separating the common potential
for the internal 24 V DC supply from the common
potential of the external 24 V DC supply.
NB!:
Please note that when Switch 4 is in position
"OFF", the external 24 V DC supply is galvanically
isolated from the frequency converter.
Electrical installation - control cables
All terminals for the control cables are located under
the protective cover of the frequency converter. The
protective cover (see drawing) can be removed by
means of a pointed object - a screwdriver or similar.
Once the protective cover has been removed, the
actual EMC-correct installation can start. See drawings
in the section, EMC correct installation.
