8.6.4 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 for 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 drawing Diagram showing 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 force the switch over. It is recommended to remove the LCP
fixture (cradle) when operating the switches. The switches must not be operated while the adjustable frequency drive is powered.
