Installation of 24 V External DC Supply
Torque: 0.5‒0.6 Nm (5 in-lbs)
Screw size: M3
24 V DC external supply can be used as a low-voltage
supply to the control card and any installed option cards.
This enables full operation of the LCP (including parameter
setting) without connection to line power. Note that a
warning of low voltage displays when 24 V DC has been
connected; however, there is no tripping.
No.

WARNING
Use a 24 V DC supply of type PELV to ensure correct
galvanic isolation (type PELV) on the control terminals of
the adjustable frequency drive.

7.5.4 Switches S201 (A53), S202 (A54), 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 Figure 7.43.
Default Setting:
S201 (A53)=OFF (voltage input)
S202 (A54)=OFF (voltage input)
S801 (Bus termination)=OFF
