1 The panel cutout with proper dimensions as shown the unit into the panel with the help of clamp equipment in its installed state must not come inclose proximity to any heating sources, caustic vapors,oils, steam, or other unwanted process safety related codifications, symbols and instructions that appear in this operating manual or on the equipment must be strictly followed to ensure the safety of the operating personnel as well as the instrument. If the equipment is not handled in a manner specified by the manufacturer it might impair the protection provided by the equipment. Read complete instructions prior to installation and operation of the unit. WARNING : Risk of electric prevent the risk of electric shock power supply to theequipment must be kept OFF while doing the wiringarrangement. Do not touch the terminals while power isbeing eliminate electromagnetic interference use short wirewith adequate ratings; twists of the same in equal size shallbe made.

2 For the input and output signal lines, be sure touse shielded wires and keep them away from each used for connection to power source, must have a2 cross section of 1mm or greater. These wires shallhaveinsulation capacity made of at least extending the thermocouple lead wires, always usethermocouple compensation wires for wiring. For the RTDtype, use a wiring material with a small lead resistance (5 max per line) and no resistance differentials among better anti-noise effect can be expected by usingstandard power supply cable for the powering up for the first time, disconnect theoutput Protection : The unit is normally supplied without apower switch and fuses. Make wiring so that the fuse isplaced between the mains power supply switch and thecontroller. (2 pole breaker fuse - rating : 275V AC,1A forelectrical circuitry is highly recommended) this is a built-in-type equipment (finds place in maincontrol panel), its output terminals get connected to hostequipment. Such equipment shall also comply with basicEMI/EMC and other safety requirements like BSEN61326-1and BSEN 61010 dissipation of equipment is met throughventilation holes provided on chassis of equipment.

3 Suchventilation holes shall not be obstructed else it can lead to asafety output terminals shall be strictly loaded to themanufacturer specified values / PRECAUTIONS DURING USEE lectrical noise generated by switching of inductive loads can create momentary disruption, erratic display, latch up, data loss or permanent damage to the instrument. To reduce noise:a) Use of snubber circuits across loads as shown above, is recommended. b) Use separate shielded wires for inputs.

Considerthe actual application conditions and use the productwithin the rated load and electrical service the relay output is rated at 5/10 amps it isalways necessary to use an interposing relay orcontactor that will switch the load. This avoids damage tothe controller in the event of a fault short developing onthe power output use a separate fused supply for the power load circuit and do not take this from the live and neutralterminals supplying power to the controller.
