4.Installation and Wiring
User’s manual 65
Wire the external power supply to the T2N power supply module in the following
manner.
When using expansion units, arrange for power to be supplied simultaneouly to
the basic unit and the expansion units (or to the expansion units before the
basic unit).

The 24Vdc power cables must be suppressed with ferrite cores, immediately
adjacent to the power supply module(s).
Use crimp-style terminals with sheaths as far as possible for wiring to the
power supply module. When it is not possible to use crimp-style terminals
with sheaths, cover with insulating tape so that the conductive parts are not
exposed.
Normally, the LG and FG terminals are
shorted.
However, depending on grounding
environment (such as when there is a
problem with leakage current or when the
power supply ground is separate), open the
LG terminal or provide a dedicated ground.
