7 Electrical connection
Semi-hermetic compressor, condenser fan and elec-
trical accessories correspond to the EU Low Voltage
Directive 2014/35/EU.
The ECOLITE condensing unit is provided exclusively
for the connection to TN-C-S or TN-S three-phase
power supply systems with a nominal voltage 230/400
V Δ/Y at a nominal frequency of 50 Hz. The connection
of a neutral conductor is mandatory. A nominal supply
voltage with qualitative characteristics according to DIN
EN 50160 is required. The ECOLITE condensing unit is
provided for a stationary installation.
Type gG fuses or line protection switches with C char-
acteristic must be provided.

Depending on local conditions and applicable regula-
tions, a supply disconnecting device must be provided
on site. The service switch provided in the ECOLITE
condensing unit does normally not fulfil the require-
ments regarding an electrical disconnection of the
device.
