Installation
2.7 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 installation 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.
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.
The pump may be operated only with a suitable frequency con-
verter and a suitable connector cable.
Peak voltages of up to 130 V may be present at the connector line
between the frequency converter and the pump; mains voltage 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 polyphase network between
two phases, provide additional external fuse protection for both phases
(fuse amperage: 16 A). The external fuse must have a minimum rated bra-
king capacity of 5 kA.
Only adequately trained electrical/electronic personnel may con-
nect-up the equipment in accordance with valid IEC (internatio-
nal), EN (European) and/or national guidelines, or under their
management and supervision.
The connecting cables between the converter and pump may
only be inserted or removed when the pump is switched off and
stands still after the run-down procedure and the converter is iso-
lated from the line supply.
Do not switch on frequency converter until all cables have been
connected properly.
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 converter, isolate the converter
from the line supply, and lock the switch so that it cannot be acci-
dentally switched on again.
In addition the pump has to stand still because it works as gene-
rator as long as it rotates, and the pump cables have to be
disconnected.
