ABB AC 800F

5 AC 800F Functional Description
5-10
Connector pin assignment
DC mains connector
Use the ready-made TK 802F
power cable for connecting a
24 V DC supply voltage, see
Section 4.1.5.
Fig. 5-11 Pin assignment of DC mains connector
Note that power supply module SD 812F must be supplied with extra
low voltage with protective separation from other circuits.
Diagnostic connector
Use one of the ready-made
TK 890F or TK 891F cables for
connecting a diagnostic interface,
see Section 4.1.5 and Section 5.4.
