The compressor system is completely finished
at the factory according to EN 60204 (Industrial
Machinery).
The power supply to the compressor must be
suitable for industrial equipment and must meet
all requirements of EN60204-1/IEC60204-1.
If the installation conditions deviate from the
conditions as described in EN 60204, consult
Gardner Denver.
Provide the electrical connection and protective
measures according to VDE, BS, or local
requirements. As a rule, additional regulations
from the corresponding power company must
also be complied with.
A main switch must be fitted on-site upstream
of the compressor (DIN EN 1012 - 1) insofar
that such a switch has not already been fitted
in the factory as a special accessory. The main
disconnect switch must meet the requirements
of the safety standard EN 60 204-1 (Electrical
Equipment for Machinery) and EN 60947-2
(Low Voltage Equipment).
The compressor must be protected by suitable
line fuses according to EN 60269-1 (Low
Voltage Directive).
If other electrical circuits are run to the
electronic controller afterward, such as lighting,
heating, or the like, that are not disconnected
by the main disconnect switch, then these
excepted electrical circuits must be labeled and
run separately per EN 60204. Warning labels
must also be installed near the main disconnect
switch and near these circuits.
Should an electrical connection to an
unearthed AC electrical circuit (IT network) be
made, observe the instructions in the supplied
documentation of the frequency converter (only
RS compressors).
