External 24 V DC supply
Description
An external 24 V DC supply is always recommended if communication and closed-loop
control are to be independent of the supply system. An external auxiliary supply is
particularly recommended for low-power lines susceptible to short-time voltage dips or power
failures.
With an external supply independent of the main supply, warnings and fault messages may
still be displayed on the operator panel and internal protection and monitoring devices if the
main supply fails.
The power requirement is 4 A.
Connecting
Connect the external 24 V DC supply to terminals 1 (P 24 V) and 2 (M
ext
) of terminal block –
