This "Safety" chapter describes the safety-related items that users should be
aware of upon handling this system.
This system, which is operated under high voltage, is outfitted with the parts
that cause a rise or drop in temperature and rotating parts when it is in action.
All personnel who work with or around this system are required to thoroughly
read and understand the safety-related items in this manual prior to working
with or around this system.
This manual is not intended to be used as a manual for comprehensive safety
and hygiene education. Such a manual should be provided by a safety training
manager.
The product is operated at high voltage and contains components which become
hot and rotate. If a component needs to be replaced or repaired, contact a

A safety manager is responsible for observing safety standards. Operators and
maintainers, however, are to have individual responsibilies for complying with
the safety standard in his/her daily work.
Operators and maintainers must individually take account of safety and assure a
proper working area and working environment.
The relevant personnel must receive proper safety education prior to work
training on this system. Otherwise, personnel may be exposed to hazards. Never
conduct work training without giving proper consideration to safety.
Do not use the materials that rust or corrode for the circulating fluid and facility
water circuits. Using the materials that tend to rust or corrode may cause clogs
or/and leakages of the circulating fluid and facility water circuits. In case of
using these kind of materials, consider and carry out some prevention against
the rusting or corrosion on the customer side.
Save this manual at a designated place for reference when necessary.

1.5.3 Lockout/Tagout
Summary
Lockout in this system disables the main breaker operation to prevent electric
shocks.
Tagout, to be placed on a locked out main breaker, to prevent improper breaker
operation (ON) conducted by other personnel.
See “Lockout procedure” in the following pages for practical lockout/tagout.
Figure 1-11 Lockout/Tagout
Those who engage in service of this system should build an awareness of the
importance of lockout. Thorough understanding of the procedures defined in this
manual are required for system service.
Lockout is allowed only when the system come to a full stop.
A supervisor should be appointed to direct all personnel if multiple workers
engage in system service.
The supervisor is to perform lockout based on a full understanding of overall
process conditions.
Not only all personnel but new personnel that engage in service of this system
should build an awareness of the importance of lockout and obtain thorough
understanding of the lockout procedure.
Any personnel working in an area with high voltage should be assigned with
padlocks and tags. The key for the padlock is kept under the responsibility of the
supervisor, and lockout release is performed upon completion of work.

1.6 Emergency Measures
1.6.1 Emergency off [EMO] switch
Press the red emergency off [EMO] switch on the front of the system only if the
need to shut off the power arises due to emergency such as natural disaster, fire,
earthquake or personal injury.
The emergency off [EMO] switch is a large, red mushroom-shaped push button
labeled with ‘EMO’ on it. The system comes to a halt if this button is pressed.
When press the emergency off [EMO] switch, the control power for this system is
shut off to bring the system to a stop. The main breaker of this system, however, is
designed not to trip, which enables the motor circuit to remain partially energized.
“8.1.3Communication specification” in Chapter 8 Appendix on page 8-7 to view
the circuit diagram and see how the EMO switch is interconnected to the system.
Restart of this system is enabled only when this button is reset manually.

Reset of emergency off [EMO] switch
1. Before restarting, always make sure that the cause of the emergency off condition (The
reason why the EMO switch was activated) has been eliminated from the power supplies,
the system and peripheral equipment.
2. With the cause completely eliminated,
turn the emergency off [EMO] switch
clockwise to reset.
The EMO button returns to its original position.
3. The screen then changes from the “Model Indication screen” to “Status screen 1” as power
is being restored to the system.
Figure 1-17 Emergency Off [EMO] Switch
No automatic recovery is applied to the emergency off [EMO] switch.
Always eliminate the cause of activating the EMO before resetting.
Potential serious accidents may occur if disregarded.
When the system is in remote mode, the remote mode is retained despite the
power outage. Thus the system operation is to resume as the start signal is
issued from your system.
No automatic recovery is applied to the emergency off [EMO] switch.
Always eliminate the cause of activating the EMO before resetting.
Potential serious accidents may be concerned occur if disregarded.
