NOTE
To comply with EMC emission specifications, screened/
armoured cables are recommended. If an unscreened/
unarmoured cable is used, see 4.6.13 Power and Control
Wiring for Unscreened Cables. If unscreened control cables
are used, it is recommended to use ferrite cores to
improve EMC performance.

Connect the wires as described in the Operating
Instruction for the frequency converter. Remember to
connect the shields in a proper way to ensure optimum
electrical immunity.

Switches S201, S202, and S801
Switches S201 (A53) and S202 (A54) are used to select a
current (0-20mA) or a voltage (-10 to 10V) configuration of
the analog input terminals 53 and 54 respectively.
Switch S801 (BUS TER.) can be used to enable termination
on the RS-485 port (terminals 68 and 69).
See Illustration 4.39
Default setting:
S201 (A53) = OFF (voltage input)
S202 (A54) = OFF (voltage input)
S801 (Bus termination) = OFF
