2. INSTALLATION DETAILS
2.1 How to Install
Mounting method: Panel mounting
To install the controller select a location where:
no one may accidentally touch the terminals
mechanical vibrations are minimal
corrosive gas is minimal
temperature can be maintained at about 25˚C to 35˚C and the fluctuation is
minimal
no direct radiant heat is present
no magnetic disturbances are caused
no wind blows against the terminal board
no water splashed
no flammable materials are around
Turn off the power to the controller before installing it on the panel because there is
a possibility of electric shock

2.3 How to connect wires
Before carrying out wiring, turn off the power to the controller and check that the
cables to be connected are not alive because there is a possibility of electric shock.
NOTE:
All wiring must confirm to appropriate standards of good practice and local
codes and regulations. Wiring must be suitable for Voltage, Current and
temperature rating of the system.
Provide power from a single-phase instrument power supply. If there is a lot of
noise in the power line, insert an insulating transformer into the primary side of
the line and use a line filter on the secondary side. Do not place the primary
and secondary power cables close to each other.
For thermocouple input, use shielded compensating lead wires for wiring. For
RTD input, use shielded wires that have low conductor resistance and cause no
significant differences in resistance between the three wires. Do not connect
Terminal –23 when thermocouple or Linear input is selected.
Use repeater after each set of 32 instruments connected in RS-485
Communication.
Unused terminals shouldnot be used as jumper points asthey may be internally
connected, which may cause damage to the unit.
CAUTION:
High voltage transients may occur when switching inductive loads such as some
contactors or solenoid valves. Through the internal contacts, these transients may
introduce disturbances which could affect the performance of the instrument.
For this type of load it is highly recommended that a “snubber” is connected across the
normally open contact of the relay switching through load. The snubber recommended
consists of a series connected resistor/capacitor (typically 15nF/100Ohms). A snubber
will also prolong the life of the relay contacts. A snubber should also be connected
across the output of a triac output to prevent false triggering under line transient
conditions.
