3.5 Output Connections
3.5.1 Output Wiring
The output terminal block (TB3) for each chassis is located at the rear of the unit to the left when
als from the master FCS18 and the
l
facing the rear. Three phase output connections are made to the terminal block labeled “TB3”
and “OUTPUT”. For mulit-box systems, the output termin
Auxiliary FCS18(s) must be connected together using the provided marathon block and equa
length wires.
Table 3-2: FCS18 Rear Panel Connections
The phase outputs are labeled øA, øB, øC and NEUT. If the power source is a single-phase
model (-1) or a three-phase model (-3) operated in single-phase mode, all power is available
from the øA output connection and the neutral connection (NEUT).
The external sense inputs (TB2) allow the power system output voltages to be monitored directly
at the load and
MUST
be connected at the external sense connector on the lower rear panel.
The external sense wires should be run as twisted pairs for short lengths. Sense leads over
three (3) feet long should be run as a twisted shielded pairs.
Note: The sense connections (TB2) MUST be made at all times. There is no internal
sense mode that would allow these connections to remain open. Sence
connections can be made to TB3 or to the actual load.
