“Electricité de France” (EDF)
When the EDF-option is installed, the unit operates as
a standard unit when the neutral and the PE terminals
are connected to each other (see figure below). In this
case, an earth leakage at the side of the generator or at
the side of the load will switch off the circuit breaker.
When EDF-option is installed, the unit operates as
EDF-unit when the earthing, the PE and the PE EDF
terminals are connected to each other (see figure
below). In this case, an earth leakage at the side of the
generator will switch off the circuit breaker. An earth
leakage at the side of the load will not switch off the
circuit breaker.
COSMOS™
COSMOS™ is a web-based global remote
monitoring system that electronically tracks every
aspect of equipment from its location to its operating
parameters. The Cosmos system can send e-mails or
SMS messages to the contractor or owner in real time,
with all critical and non-critical events and data
involving your compressors and generators. It allows
optimal servicing.
When starting up the generator, the green Power Led
(1) of the Cosmos module will light up when the
installation has been carried out correctly.
For information about COSMOS™, consult your
local Atlas Copco dealer.
