Before you begin
Before connecting any power cables be sure that all circuit breakers which are located
in the external Battery Distribution and Fuse Bay (BDFB) and/or on a Power
Distribution Panel (PDP) are in the
OFF position.
Important! The power cables should be connected later (see section “Switching on
and testing supply voltage” (p. 5-3)).
DC connector data
The DC connector is a 6-pin terminal block connector with screw down contacts.
Table 4-2 Pin assignment (power cables, AMS unit)
Point on Connector Signal Name Color
1 –24/–48/–60 VDC, feed A blue
2 DC RTN (return), feed A red
3 –24/–48/–60 VDC, feed B blue
4 DC RTN (return), feed B red
5 DC common return for feed A+B red
6 GND (common ground) yellow/green
AC connector data
The AC connector is a 3-pin IEC 60320 universal connector (input power range: 90 to
264 VAC).
Cable data
Preferably stranded 1.3 mm
2
wires with proper insulation should be used.
Cable connection
The power cables must be connected as shown in the figures below.
NOTE: If an AC/DC converter is used, the DC side needs to be connected to the 1643
AMS and the AC side needs to be connected to a power outlet.
