Operation
Once programmed, calibrated, installed, and supplied
with the correct power, the TMZ transmitter begins to
operate immediately. Depending upon environmental
conditions, it can be expected to operate unattended
for extended periods of time.
Maintenance
Moore Industries suggests a check for terminal tight-
ness and general unit condition every 6-8 months.
Always adhere to any site requirements for pro-
grammed maintenance.

Making the Electrical
Connections
Please refer to Figure 4 for electrical connections.
Recommended Ground Wiring
Practices
Moore Industries recommends the following ground
wiring practices:
• Any Moore Industries product in a metal case or
housing should be grounded.
• The protective earth conductor must be connected
to a system safety earth ground before making
other connections.
• All input signals to, and output signals from,
Moore Industries’ products should be wired using
a shielded, twisted pair wiring technique. Shields
should be connected to an earth or safety ground.
• 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
classified as receivers (IPT
2
, IPX
2
, etc.) and some
can be classified 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.
Installation
Installation consists of physically mounting the unit
and completing the electrical connections.
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.
