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 any
other connections.
• All input signals to, and output signals from, Moore
Industries’ products should be wired using a
shielded, twisted pair technique. Shields are to be
connected to an earth or safety ground at the unit
itself.
• The maximum length of unshielded input
and/or output signal wiring should be
two inches.
CE Conformity
Installation of any Moore Industries’ products that
carry the CE certifi cation must adhere to the
guidelines above in order to meet the requirements set
forth in the European EMC and Low Voltage Directives
(EN 61326 and EN 61010). Consult the factory for the
most current information on products that have been
CE certifi ed.
Operation
Once programmed, calibrated, installed, and supplied
with the correct power, the CPT 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
tightness and general unit condition every 6-8
months. Always adhere to any site requirements for
programmed maintenance.
