2 Safety Instructions

2.1 Before using the Thermo-con

This chapter is dedicated for your safety during interaction with the product.
The product is operated at high voltage.
Therefore, not only those who operate the unit, but those who are in charge of service and who work

nearby the product should read carefully and thoroughly understand descriptions related to safety in this
manual before starting the work.

2.1.1 Safety training

This manual is not a general manual for safety and hygiene education that safety and hygiene tutors are
supposed to conduct.

Anyone working with or near the product should be fully trained in recognition of the danger inherent to
the product and the related safety countermeasures.

A manager is responsible for strict compliance to the safety standard in whole system, but individual
person in charge of operation and maintenance should take responsibility for the daily work and should
consider the safety of the working location and environment.

Operators and maintenance personnel responsible should ensure the safety of workshops and their
environment before starting work.

Training concerning the product should take place after the sufficient training on safety. The training
must not be carried without consideration to safety.

2.1.2 Identification of “Danger”, “Warning”, “Caution” and “Note”

The notifications given in this operation manual aim to assure the safe and correct operation of the
product to prevent injury of operators or damage to the product. The notifications are grouped into four
categories, “Danger”, “Warning”, “Caution”, and “Note”, which indicate the severity of the hazard and
damage and also the degree of emergency. All notifications contain critical matter on safety, so they
shall be carefully observed.

DANGER, WARNING, CAUTION and NOTE signs are in order according to severity (DANGER>
WARNING> CAUTION> NOTE).

2.2 “Warning” label and “Caution” label

This product is provided with “Warning” labels and “Caution” labels to inform the operator of hazards
related to the product. Check the contents and position of all labels before starting the work.

The product shall be handled only by trained personnel only.
Transportation, installation and maintenance including dangerous work
shall be done by persons who have full knowledge and experience on
the product and the system. Cover panels of the product shall be
opened only by qualified service technicians or qualified personnel.

Read all warning and caution labels carefully and keep them in mind. Do
not peel off or rub alert warning and caution labels.
Confirm locations of alert warning and caution labels.

This product cannot be used for the device related to food.

2.3 Precautions for running (safety interlock)

This is a function to protect personnel, to restrict operation, that may cause damage to the product or
facility, and to remove dangers related to safety.

This unit has several interlock functions, which activate when dangerous operation or condition occurs to
stop operation and make it safe.

See “2.3.1 Interlock list” for contained function.

During operation or maintenance of the product, do not disable the
interlock function of any device. Otherwise unexpected personnel injury
or damage to the product may occur.

When turning on/off the power observe the procedure. Otherwise
unexpected malfunction or danger may occur.

When maintaining, cleaning or in case of emergency, turn off the power
source.

After identifying a problem be sure to check the cause and take
necessary countermeasures before turning on the power.

When the power supply is restarted after turned off once, keep time
interval at least 1sec. The restart of supply within that interval may break
the unit.

Please do not use the device which generates the electromagnetic
radiation such as cellular phones beside the unit. There is a possibility
that the unit mis-operates.
