Electrical voltage
Residual voltage of the
capacitors
Warning of dangerous, electrical voltage.
Warning of electrical energy stores in the form of capaci-
tors. These can conduct a life-threatening electrical volt-
age.
Only open the switch cabinet (RS compressor or
ARV
)
10 minutes after switching the compressor to a volt-
age-free state.
Only a qualified electrician following electrotechnical reg-
ulations may carry out work on the electrical equipment

The precise position of the terminals "DC+" and "DC-"
can be taken from the supplied frequency converter
operating instructions.
Spring tension
Warning of tensioned spring inside the suction regulator.
Before opening the suction regulator read the repair
manual.
