• The LCD display contrast changes depending on the angle from
which it is viewed. Install it in a position that ensures a suitable angle
of view.
• Tighten screws using a torque of approx. 0.3~0.5N·m
• To prevent damage to the LCD, take care not to subject the LCD/
front of the main unit to shock/impact.

CAUTION CONNECTIONS
• To ensure safety, connections are to be performed by an electrical
engineer qualified in wiring.
• Check connection diagrams carefully before performing connections.
Incorrect connections may result in VT burnout caused by a VT
secondary-side short circuit or high voltage on the CT secondary
side, which may lead to device malfunction, fire or electrical shock.
• Do not work with live wires; there is a risk of electric shock and
exposure to high voltage due to short-circuiting or CT secondary
side opening, which may lead to malfunction, fire or electrical shock.
• Use electrical wire sizes compatible with the rated current. Use of
unsuitable sizes may cause heat generation, which may lead to a
fire.
• After performing connections, check that no connections have been
missed. Missed connections may result in erroneous operation or
high voltage on the CT secondary side, which may lead to a fire or
electrical shock.
nPREPARATIONS BEFORE USE
• Before use, perform settings such as the VT primary voltage, CT
primary current, power scale and demand time limit in accordance
with the operations manual supplied with the product; setting errors
may cause incorrect measurement/operation.
nUSAGE PROCEDURES
• Use the products within the rated range. Using the products
outside the rated range may cause erroneous operation or product
malfunction.
• Do not use the products for special applications such as nuclear
power, aerospace or medical devices/systems.
CAUTION Do not make any modifications to the products. Using
products after modification may cause a malfunction, electrical shock
or fire.
nREPAIRING AT TIME OF MALFUNCTION/ERROR
• If a product listed in this catalog malfunctions, read the
troubleshooting section of the operations manual (detailed version)
and confirm the symptoms. If the problem is not listed, please
