• For the best shielding, the shield should be run all
the way from the signal source to the receiving
device. (see Note below)
• The maximum length of unshielded input and
output signal wiring should be 2 inches.
Note:
Some of Moore Industries’ instruments can be
classifi ed as receivers (IPT
2
, IPX
2
, etc.) and some can
be classifi ed as transmitters (TRX, TRY, etc.) while
some are both a receiver and a transmitter (SPA
2
,
HIM, etc). Hence, your shield ground connections
should be appropriate for the type of signal line being
shielded. The shield should be grounded at the
receiver and not at the signal source.
CE Conformity
Installation of any Moore Industries’ products that
carry the CE marking must adhere to the
guidelines in the Recommended Ground Wiring
Practices section in order to meet the EN 61326
requirements set forth in the applicable EMC
directive.

Supply air must be clean, dry instrument air. It is
recommended that all particles larger than 1 micron
be removed. Use of ¼-inch tubing allows suffi cient
air for one unit. When using RIR or SIR headers,
up to 30 IPT
2
s may be run from a ¾-inch NPT pipe
without degrading performance, provided the air
supply pressure is suffi cient. Output tubing should
be ¼-inch, though larger tubing may be desirable for
exceptionally long runs. Purge the output tubing and
the controlled device before connecting to the IPT
2
or
RIR/SIR.
Caution:
Output air cycles back through the IPT
2
.
Contamination in the output line or controlled
device may easily enter and damage the IPT
