Warning
Unauthorized opening of the converter
voids the warranty.
Hazardous voltages are present inside the
converter. Death or severe injury can occur
if you come into contact with these hazar-
dous voltages. Before opening the conver-
ter, isolate the converter from the line supp-
ly, and lock the switch so that it cannot be
accidentally switched on again.
In addition the pump has to stand still
because it works as generator as long as it
rotates, and the pump cables have to be
disconnected.
Installation instructions to maintain EMC
The MAG.DRIVE
digital
complies with the Electromagnetic
Compatibility (EMC) Directives of the EC. In order to
maintain this the following installation instructions must
be observed:
•
To connect the pump to the converter the prescribed
Leybold cables must be used.
•
The connection cables to the analog interface (con-
trol plug X14) and to the serial interface (connector
X7) must be shielded. The shields must be connected
to the metal housings of the SUB-D-connector and
SUB-D-socket.
2.8.1 Power supply connection X19
The converter is ready to be connected to line supply
voltages between 200-240 V 50/60 Hz. The connection
is established using the power cable supplied, which is
inserted at connector X19 at the rear of the converter.
Caution
The converter will be damaged if it is ope-
rated with the incorrect supply voltage.
2.8.2 Pump connection
Warning
To avoid contact with hazardous voltages in
case of malfunction the pump must be
connected to PE.
Connect the converter (X20) to the motor and magnetic
bearing connection of the pump (X23) and the PK com-
munication connection (X24) using the DRIVE/ BEA-
RING cable.

GA 05.141/6.02 - 07/2003
2.8 Installing the
MAG.DRIVE
digital
The converter can be installed in a 19” cabinet. It is 1/2
of 19“ wide and has 3 height units. For easier installati-
on we offer an installation frame; see Section 1.7. If you
use this installation frame, remove the converter’s rub-
ber feet when installing the converter.
Caution
In order to guarantee sufficient cooling,
there must be a minimum clearance of 1
height unit (44.2 mm) at the bottom and 1
height unit at the top. During operation the
temperature of the ambient air must not
exceed 45
°
C.
Warning
The pump may be operated only with a sui-
table frequency converter and a suit-
able connector cable.
Peak voltages of up to 130 V may be pre-
sent at the connector line between the fre-
quency converter and the pump; mains vol-
tage is present at the heater.
Route all cables so as to protect them from
damage.
The protection rating for the connectors is IP 30.
Do not expose the pump, the frequency converter or the
connections to dripping water.
Install 16 A fuses for the converter.
When connecting the frequency converter to a polypha-
se network between two phases, provide additional
external fuse protection for both phases (fuse ampera-
ge: 16 A).
Warning
Only adequately trained electrical/electronic
personnel may connect-up the equipment
in accordance with valid IEC (international),
EN (European) and/or national guidelines,
or under their management and supervisi-
on.
Warning
The connecting cables between the conver-
ter and pump may only be inserted or remo-
ved when the pump is switched off and
stands still after the run-down procedure
and the converter is isolated from the line
supply.
Do not switch on frequency converter until
all cables have been connected properly.
