Low Voltage Directive
When installing any Moore Industries product,
always follow all local regulations and standards for
grounding, shielding, and safety. The following
grounding and wiring practices must be followed in
order for the unit(s) to meet the requirements set
fourth in the EMC directives EN50082-2 and
EN55011.
Grounding
If the unit has a metal case it is to be grounded.
(DIN rail mounted units should be mounted on a
grounded rail).
Wiring
Twisted shielded wire should be used for all input
and output signals. The shields are to be grounded
at the units, to earth ground (safety ground). The
unshielded part of the in/output wires should be no
longer than 2 inches.
CE Certification-related Guidelines
The following guidelines must be followed in order to
comply with EN61010-1 (Low Voltage Directive).
These items affect the AC version of the TRZ. If
these products are to be used in a non-CE
environment, this directive may be disregarded.
WARNING:
If this unit is used in a manner not specified by
Moore Industries, the protection provided by the
equipment may be impaired.
Switches and Circuit Breakers
A switch or circuit breaker must be wired in series
with the AC power conductors. The switch or circuit
breaker used must be located within three meters of
the unit.
WARNING:
Terminals on this unit may be connected to
hazardous voltages. Before making ANY
connections to this unit, ALL hazardous voltages
must be de-energized.
The circuit breaker or switch will only remove
power to the unit, hazardous voltages may still be
connected to other terminals on the unit.
Installation Category
All of Moore Industries’ terminals are rated CAT II,
except those with the -RF option. These terminals
are rated CAT I.
Equipment Ratings
The TRZ does not generate hazardous voltages,
rather, it accommodates a temperature input, and
generates a 4-20mA current output. Products
connected to the TRZ should be designed to receive
these inputs.
Supply Wiring
All power connections should be made with proper
wire.
The end of each conductor should be stripped no
more than 8mm. The end of the stripped wire
should be tinned with solder, or inserted into a
ferrule and crimped before being placed into a
terminal block.
Conductors connected to screw-type connections
should have a ring-lug or spade-lug crimped onto
the wire end.
