Handling Precautions
These handling precautions address issues that can potentially cause the product to
malfunction.
Power and Usage Environment

Use the rated power only.

Maintain the controller's ambient temperature between - 10℃ and 50℃.

Turn the power on and allow the temperature controller to warm-up for twenty
minutes before use.

A power switch or a circuit-breaker is necessary to supply and cut off power to the
product.

Install the switch or circuit-breaker in the vicinity of the product to facilitate easy
access.

Use the product in a well-ventilated environment. Otherwise, arrange for ventilation if
necessary.

Recommended usage conditions are as follows:

Indoors

Below 2,000 m altitude

Pollution Degree 2

Installation Category II
Sensor Input

If using in an environment where the margin of sensor error cannot be avoided, use
the Input Bias feature to minimize the error margin.

If using a thermocouple sensor, make sure to use prescribed compensation wire as
extension wire. Failure to do so will produce temperature distortion at the junction
between the thermocouple and the extension wire.

If using a resistance temperature detector (RTD) sensor, always make connection
with three-wire configuration. In addition, only use three wires of identical material,
thickness and length if you need to extend the line. Variance in wire resistance will
lead to temperature distortion.
