Page 10 Do not use the unit in an atmosphere where combustible gas is present. • Doing so may result in inflammation, ignition, or smoke. Do not cover the ventilation slits with cables, etc. • Doing so may result in malfunction or heating. 47DAC OPERATING MANUAL EM-9518-B Rev.4...
Page 11: Points Of Caution
• Prepare Infrared Communication Adaptor (model: COP-IRU) separately for the infrared communication. • Transmission distance between the 47DAC and the COP-IRU is maximum 1 meter. • Communication can be affected by sunlight, fluorescent lightings employing inverter technology and so forth. Try at a shorter distance if communication is not established.
Page 12 To ensure dustproof and waterproof for front panel follow conditions below. • Observe the designated panel cutout size (W92 × H45 mm) specified by M-System. • The watertight packing included in the product package must be placed between the body and panel when installing on the panel.
