Installation of 24 V external DC Supply
Torque: 0.5 - 0.6 Nm (5 in-lbs)
Screw size: M3
No. Function
35 (-), 36 (+) 24 V external DC supply
Table 7.37 24 V External DC Supply
24 V DC external supply can be used as low-voltage supply
to the control card and any option cards installed. This
enables full operation of the LCP (including parameter
setting) without connection to mains. Note that a warning
of low voltage will be given when 24 VDC has been
connected; however, there will be no tripping.
WARNING
Use 24 VDC supply of type PELV to ensure correct galvanic
isolation (type PELV) on the control terminals of the
frequency converter.

7.5.4 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
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 7.55.
