Electrical noise generated by switching of inductive loads and can create momentary disruption, erratic display, latch up, data loss or permanent damage to the instrument. To reduce noise:a) Use of MOV across supply of temperature controller & snubber circuits across loads are recommendedb) Use sCONNECTION DIAGRAM :1) FOR THERMOCOUPLE TC+TC-10987 6 THERMOCOUPLE+-1) FOR TWO WIRE PT-100: Short terminals 8 & 9.

5 Confirm that all connections are lugged terminals to meet M3 eliminate electromagnetic interference use of short wire with adequate ratings and twists of the same in equal size shall be used for connection to power source, must have 2 a cross section of 1mmor wires shall have insulation capacity made of at least equipment should be cleaned regularly to avoid blockage of ventilating the equipment with a clean soft cloth. Do not use Isopropyl alcohol or any other cleaning equipment, being built-in-type, normally becomes a part of main control panel and in such case the terminals do not remain accessible to the end user after installation and internal must not come in contact with the internal circuitry of the equipment or else it may lead to a SAFETY hazard that may in turn endanger life or cause electrical shock to the breaker or mains switch must be installed between power source and supply terminals to facilitate power 'ON or OFF function.

6 However this switch or breaker must be installed in a convenient position normally accessible to the operator.!! SAFETY SUMMARYAll 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 : Read complete INSTRUCTIONS prior to installation and operation of the unit.

CAUTION: equipment shall not be installed in environmental conditions other than those mentioned in this Protection: The equipment does not have a built-in- type fuse. Installation of external fuse of rating 275 VAC/1 Amp for electrical circuitry is highly dissipation of equipment is met through ventilation holes provided on chassis of equipment.
