manufactured goods and may not be received at the same time. Therefore this guide is provided
to ensure that printed information normally present on equipment is fully understood by the
recipient.
Before carrying out any work on the equipment, the user should be familiar with the contents of
this manual and read relevant chapters carefully.
This chapter describes the safety precautions recommended when using the equipment. Before
installing and using the equipment, this chapter must be thoroughly read and understood.
Health and Safety
The information in this chapter of the equipment documentation is intended to ensure that
equipment is properly installed and handled in order to maintain it in a safe condition.
When electrical equipment is in operation, dangerous voltages will be present in certain parts of
the equipment. Failure to observe warning notices, incorrect use, or improper use may endanger
personnel and equipment and cause personal injury or physical damage.
Before working in the terminal strip area, the equipment must be isolated.
Proper and safe operation of the equipment depends on appropriate shipping and handling,
proper storage, installation and commissioning, and on careful operation, maintenance and
servicing. For this reason, only qualified personnel may work on or operate the equipment.
Qualified personnel are individuals who:
Are familiar with the installation, commissioning, and operation of the equipment and of the
system to which it is being connected;
Are able to safely perform switching operations in accordance with accepted safety
engineering practices and are authorized to energize and de-energize equipment and to
isolate, ground, and label it;
Are trained in the care and use of safety apparatus in accordance with safety engineering
practices;
Are trained in emergency procedures (first aid).

Instructions and Warnings
The following indicators and standard definitions are used:
DANGER! means that death, severe personal injury and considerable equipment damage
will occur if safety precautions are disregarded.
WARNING! means that death, severe personal and considerable equipment damage
could occur if safety precautions are disregarded.
CAUTION! means that light personal injury or equipment damage may occur if safety
precautions are disregarded.
NOTICE! is particularly applies to damage to device and to resulting damage of the protected
equipment.
DANGER!
NEVER allow the current transformer (CT) secondary circuit connected to this
equipment to be opened while the primary system is live. Opening the CT circuit will
produce a dangerously high voltage.
WARNING!
ONLY qualified personnel should work on or in the vicinity of this device. This personnel
MUST be familiar with all safety regulations and service procedures described in this
manual. During operating of electrical device, certain part of the device is under high
voltage. Severe personal injury and significant device damage could result from
improper behavior.
WARNING!
Do NOT touch the exposed terminals of this device while the power supply is on. The
generated high voltage causes death, injury, and device damage.
WARNING!
Thirty seconds is NECESSARY for discharging the voltage. Hazardous voltage can be
present in the DC circuit just after switching off the DC power supply.
CAUTION!
Earthing
Securely earthed the earthing terminal of the device.

Preface
PRS-7910 iii
Operating environment
ONLY use the device within the range of ambient environment and in an
environment free of abnormal vibration.
Ratings
