Switches S201, S202, and S801
Switches S201 (A53) and S202 (A54) are used to select
a current (0-20 mA) or a voltage (-10 to 10 V)
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 Power Wiring Diagram in the VSD
Interconnect Guide for all electrical terminals.
Default setting:
• S201 (A53) = OFF (voltage input)
• S202 (A54) = OFF (voltage input)
• S801 (Bus termination) = OFF
When changing the function of S201, S202 or
S801 be careful not to use force for the switch over. It is
recommended to remove the LCP fixture (cradle) when
operating the switches. The switches must not be
operated with power on the frequency converter.
