13) A switch or circuit breaker should be provided close to this Unit. The switch or circuit breaker should be
within easy reach of the operator, and must be marked as a disconnecting means for this unit.
14) Approximately 30 minutes is required for the correct temperature to be displayed after turning the
power supply to the Temperature Controller ON. Turn the power supply ON at least 30 minutes prior to
starting control operations.
15) Be sure that the platinum resistance thermometer type and the input type set on the Temperature
Controller are the same.
16) When extending the thermocouple lead wires, always use compensating conductors suitable for the
type of thermocouple. Do not extend the lead wires on a platinum resistance thermometer. Use only
low-resistance wire (5 Ω max. per line) for lead wires and make sure that the resistance is the same for
all three wires.
17) When drawing out the Temperature Controller from the case, do not apply force that would deform or
alter the Temperature Controller.
18) When drawing out the Temperature Controller from the case to replace the Temperature Controller,
check the status of the terminals. If corroded terminals are used, contact faults with the terminals may
cause the temperature inside the Temperature Controller to increase, possibly resulting in fire. If the
terminals are corroded, replace the rear case as well.
19)When drawing out the Temperature Controller from the case, turn the power supply OFF first, and
absolutely do not touch the terminals or electronic components or apply shock to them. When inserting
the Temperature Controller, do not allow the electronic components to come into contact with the
case.
20) Static electricity may damage internal components. Always touch grounded metal to discharge any
static electricity before handling the Temperature Controller. When drawing out the Temperature
Controller from the case, do not touch the electronic components or patterns on the board with your
hand. Hold the Temperature Controller by the edge of the front panel when handling it.
21) Do not use paint thinner or similar chemical to clean with. Use standard grade alcohol.
22) Use tools when separating parts for disposal. Contact with the sharp internal parts may cause injury.
