5.2 Installation instructions
5.2.1 Connecting power supply cables
• The rated voltage and rated frequency of the DRC drive unit must correspond with
the data of the power supply system.
• Cable cross section: According to input current I
line
at rated power (see chapter
"Technical data and dimension sheets").
• Install line fuses at the beginning of the power supply cable behind the supply bus
junction. Select the fuse size according to the cable cross section.
• Use only copper cables with a minimum temperature range of 85 °C as connection
cable.
• DRC drive units are intended to be operated on voltage supply systems with
grounded star point (TN and TT systems).
