Installation
Please note the following items regarding installation. To ensure safety, installation is to be performed by a qualified technical electrician.
• Affix the main unit to the panel before use • 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. 0.3-0.5 N·m • To prevent damage to the LCD, take care not to subject the LCD/front of the main unit to
shock/impact.

Repairing 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 contact a Mitsubishi Electric representative.
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:
q Check for damage to the product w Check for display malfunctions (e.g., does not respond to input) e Check 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)
r
Check 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°C to +75°C • Daily average temperature of more than 35°C • Relative humidity exceeding 85% RH 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

Disposal
• These products do not use nickel-cadmium batteries. Dispose of them as industrial waste.
• The optional module ME-0000BU-SS96 contains a lithium battery. Dispose of the battery in accordance with the municipal regulations.
• In EU member states, there is a separate collection system for used batteries. Dispose of the batteries properly at the local collection/recycling center. The following
symbol is printed on the package of ME-0000BU-SS96.
This symbol is applicable only in EU member states. The symbol is designated in Article 20 “Information for end-users” and Annex II of the new European
Directive on batteries (2006/66/EC).
The above symbol indicates that the batteries must be disposed of after separation from general waste.

• Do not make any modifications to the products. Using products after modification may cause a malfunction, electrical shock or fire.
CAUTION
• 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.
• At the time of wiring, an electric wire can be broken by pulling with strong power.
(The load of pulling is less than 3-9 N)
CAUTION
• The optional module ME-0000BU-SS96 contains a lithium battery. Therefore, if it is thrown into the fire, it may generate heat,
rupture or ignite. Dispose of the lithium battery in accordance with the municipal regulations.
