The compressor system is executed completely in
the factory according to EN 60204 (industrial ma-
chinery).
The compressor power supply must be suitable
for industrial equipment and must fulfil all the
requirements of EN60204-1/IEC60204-1. Con-
tact Gardner Denver if the positioning condi-
tions differ from the conditions as they are de-
scribed in EN 60204.
Implement the electrical connection and the
protective measures in accordance with VDE,
BS or the appropriate local regulations. In gen-
eral, the supplementary regulations of the re-
spective power supply utility must be consid-
ered.
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
switch must fulfil the requirements of the safety
standard EN 60 204-1 (Electrical equipment of
machines), as well as EN 60947-2 (low voltage
switchgear).
The compressor must be fused using suitable
backup fuses in accordance with EN 60269-1
(low voltage directives).
If third party circuits are retrospectively con-
trolled via the electronic control, e.g. lighting,
heating or similar, that cannot be switched off
from the main switch, these excluded circuits
must be labelled according to EN 60204 and
routed separately. Moreover, warning signs
must be attached close to the main switch and
close to the relevant circuits.
Should an electrical connection to an un-
earthed AC electrical circuit (IT network) be
made, observe the instructions in the supplied
documentation of the frequency converter (only
RS compressors).
