7
Maintenance/Inspections
• Wipe away any dust/dirt on the surface of the product with a soft cloth.
• Do not leave chemical cloths, etc. in contact with the product for long periods, and avoid the use of benzene, thinner, etc. when wiping the product surface. Doing so
may cause deformation or cause the coating to peel away.
• To ensure correct use for the full service life of the product, please perform the following inspections:
qCheck for damage to the product wCheck for display malfunctions (e.g., does not respond to input) eCheck for loose installation or terminal block wire connections
(check regularly once every six months/year) always making sure that power has been turned off beforehand). rCheck for unusual smell, noise or rise in temperature.
8
Storage
Do not store the product for long periods of time under any of the following conditions. Doing so may lead to a malfunction or reduced service life.
• Ambient temperature outside the range of -25~+75°C • Daily average temperature of more than 35°C • Relative humidity exceeding 85% or condensation present
• Excessive dust, corrosive gas, salt or oil/smoke present • Product is subject to excessive vibration or shock • Product is in direct contact with rain, water drops or sunlight
9
Disposal
These products do not use nickel-cadmium batteries. Dispose of them as industrial waste.
10
Warranty Period
The warranty period for the products in this catalog expires one year from the date of purchase or one year and six months after the date of manufacture;
whichever is earliest. Even during the warranty period, the warranty shall not apply to malfunctions attributable to intentional negligence or erroneous use by
the customer, and the fee for any repair required as the result of such negligence shall be the liability of the customer.
Mitsubishi Electric shall not be liable for: Damage that cannot be attributed to Mitsubishi Electric; lost opportunity or earnings resulting from failure of a
Mitsubishi Electric product; damage, secondary damage or compensation for an accident resulting from special circumstances regardless of whether or not
the circumstances were foreseeable; or damage to products or other services for products not manufactured by Mitsubishi Electric.
11
Product Exchange Cycle
Although it depends on usage conditions, as a guide, it is recommended that the products listed in this catalog be renewed after 10 years.
• 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.
• Do not make any modifications to the products. Using products after modification may cause a malfunction, electrical shock or fire.

Mitsubishi Electric Energy-saving Data Collection Server
Simple Set-up
When using the set-up software supplied, power management meters
connected to CC-Link and measurement data can be set by mouse and
keyboard operations.
Display Measurement Data as Graphs on a Web Browser
The main unit has a built-in web server that allows anyone, anywhere to
understand the amount of energy being used in real time via computer
without requiring additional software, thereby supporting early detection of
energy waste.
