Power Wiring
There are five terminals that provide power and ground con-
nections. See Figure
for terminal locations. Terminal E4 is
the +24 VDC power connection. Terminal E2 is the I/O com-
mon. Terminal E1, E3 and E5 are shield connections.
Make power connections to the TU after it is mounted in the
NFTP01. Make sure cabinet and I/O power are turned off
before connecting ground and power wiring. Refer to the follow-
ing steps when installing the TU into a cabinet that uses the
modular power supply system.
1. Attach a 14 AWG wire from the +24 VDC power source
within the cabinet or an ex24 VDC source to the E4 ter-
minal on the TU.
2. Attach one 14 AWG wire from the DC bus bar at the bottom
of the cabinet to the E2 terminal (I/O common) of the TU.
