Electrical installation
Detail 4: Control cables
At the control terminals (X8) of the ServoA note the following points:
• Strip the shielding of the control cables back only as short as absolutely neces-
sary.
• Connect the control cable shields across a wide area to the shield connection
tab of the mains filter by the clamp supplied. If this is not possible, lay the control
cable shielding directly across a wide area on the backing plate directly adjacent
to the ServoA.

Detail 3: Mains filter and mains connection
At the output of the mains filter and at the AC mains connection (X3):
• Connect the wire strands at the output of the mains filter directly to the AC mains
connection (X3) of the ServoA. The strands must not be extended, so the mains
filter should be installed correspondingly close to the ServoA. but be sure to
maintain the necessary minimum clearance (see table 2.2 on page 12).
• Fix the strands to the shield connection plate using a cable tie as necessary.
• The leakage current of the ServoA is >3.5 mA. So:
-Connect the protective conductor from the output of the mains filter to the con-
nection (X3) of the ServoA and
-one of the PE connections on the heat sink of the ServoA via a cable of at least
the same cross-section to the main ground of the distributor rail.
