OUTLINE
(1) Scope of this document
This document applies to the EU-m30 and bezel option OT-BU30.
(2) Product safety precautions
1) Do not allow a voltage that exceeds the absolute maximum rating to be applied to the power connector.
If the applied voltage exceeds the absolute maximum rating, excess current may flow, causing thermal damage
to components.
Absolute maximum rating
Articles Rating Units
Circuit input power supply voltage 26.4 V
Storage temperature See 1.13 Environmental Conditions (2)
Storage environment.
Storage humidity
2) Use the product within the range of operating conditions shown in the table below.
Operating conditions
Articles Min. Typ. Max. Units
Printer power supply voltage 22.3 24.0 25.7 V
Operating temperature See 1.13 Environmental Conditions (1) Guaranteed
operating environment.
Operating humidity
3) Do not create short circuits between connector terminals in the printer unit.
Do not create short circuits between power connector terminals.
A short circuit to a low-impedance power supply can create excess current, causing thermal damage to
components.
4) During transport and storage, properly protect printer unit exterior (exposed) circuit boards and electronic
components with conductive sponges, aluminum foil, and such.
5) Do not drop clips and other conductive materials onto the printer unit's circuit board.
Short circuits between component connectors (terminals) can create excess current, causing thermal damage
to components.
6) Use only the cables indicated in this document. Also, use only the wiring indicated in this document.
Wiring done incorrectly can lead to a failure, fire, explosion, or other accident.
7) Do not disassemble or modify. Such actions can lead to injury or electric shock.
8) During operation, do not directly touch gears or other moving parts. You can get cut or otherwise injured.
9) Do not install in an unstable location (such as on an unsteady pedestal or sloping area). The product can
fall and you can get injured.
10) Do not install in a damp or dusty location. Also, ensure that the product is not exposed to water droplets.
Failure to do so may result in product failure, fire, or electric shock.
11) If the product will not be used for a long period, be sure to turn off the power to the printer unit for safety.
12) The symbols shown below are used in order to ensure safety and proper use of this product.
Read and thoroughly understand the meaning of each symbol before using the product.
