(1) Data regarding the unit without accessories working in maximum power absorption conditions
(2) Datum related to the unit without accessories working in standard conditions (A35°C; W12-7°C)
(3) Maximum effective RMS value of the current when the last compressor starts (FLA of the entire unit - FLA of the largest comp LRA of the
largest compressor)
(4) Maximum effective RMS value of the current when the last compressor starts (FLA of the entire unit - FLA of the largest comp 0.6 x LRA
of the largest compressor)
(5) These values are determined for cables with operating temperature of 40°C, EPR insulation and a line with a maximum length of 50m. The line
section must be determined by a qualified technician based on the protection devices, the length of the line, the type of cable used and the type
of installation.
(6) The correct line protection part must be determined by a qualified technician based on the length of the line, the type of cable used and the type
of installation.
