3.2 Installation
3.2.1 Amplifier Installation Precautions
The amplifier must be installed in an enclosure. Carefully consider the size of the case, the cooling
method, and the location so that the ambient temperature around the amplifier does not exceed 55°C.For
longevity and high reliability, it is recommended to keep the temperature around the amplifier below 40°C.
If there is a vibration source nearby, use a shock absorber between the amplifier and the installation base
to prevent the vibration from directly affecting the amplifier.
Long-term use in the presence of corrosive gas may cause contact failure on the connectors and on
connecting parts. Never use the device where it may be subjected to corrosive gas.
Do not use the device where explosive or combustible gas is present, it can cause fire or an explosion.
Do not use the device where dust or oil mist is present. If dust or oil mist attaches to and accumulates on
the device, it can cause insulation deterioration or leakage between the conductive parts, and damage the
amplifier.
A large noise source may cause inductive noise to enter the input signals or the power circuit, and can
cause a malfunction. If there is a possibility of noise, insert a noise filter, inspect the line wiring and take
appropriate noise prevention measures.
3.2.2 Amplifier Installation Method
1 Installation dimensions
The amplifier must be installed using four M4 screws on its rear panel. Refer to the amplifier outline
drawing (Section 6.5.1) for the installation dimensions.
2 Installation direction
The amplifier uses natural convection cooling. The installation direction must be vertical. Do not install
the unit upside down.
3 Installing multiple amplifiers in a row
Leave at least 50mm of space above and below the amplifiers to ensure unobstructed airflow from the
radiator. If heat gets trapped above the amplifier, use a fan to create airflow. Leave at least 10mm of
space between the amplifiers.
