Connecting supply system cables
• The nominal voltage and frequency of the device must correspond with the data of
the supply system.
• Dimension the cable cross section according to the input current I
line
for nominal
power (see chapter "Technical data and dimension sheets").
• Install safety equipment F11/F12/F13 for line fuses at the beginning of the power
supply cable behind the supply bus junction, see chapter "Connection diagram".
Dimension the safety features according to the cable cross section.
• Use only copper conductors with a minimum temperature range of
90
°C as con-
nection cable.
