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.

Depending on the local conditions and applicable regu-
lations, the installation of a supply circuit disconnecting
device must be provided on site. The service switch
provided in the ECOLITE condensing unit does nor-
mally not fulfil the requirements regarding an electrical
disconnection of the device.
