Amplifier Installation
Condition
Recommended Precautions
Amplifier In An
Enclosure
The temperature inside an enclosure may be higher than the
outside temperature, depending on the power loss of internal
equipment and the dimensions of the box.
Be sure to determine the dimensions of the box, cooling method,
and panel layout so that the ambient temperature is lower than
55C.
Amplifier Near A
Vibrating Source
Install the amplifier with a shock absorber to dampen the vibration
that is transmitted directly to amplifier.
Amplifier Near A
Heat Source
Shield the amplifier so that convection or radiation does not raise
the ambient temperature 55C.
Corrosive Gas
Environment
If the amplifier is operated for extended time periods in a
corrosive environment, contact failure will occur at contact points
(e.g., connectors). Therefore, never install the amplifier in a
corrosive gas environment.
Explosive Or
Combustible Gas
Environment
Never install the amplifier in an explosive gas or combustible gas
environment. Relays and contactors, which generate arcs (sparks)
inside boxes and hot parts such as regeneration brake resistor, may
become ignition sources, causing a fire or explosion.
Dust And Oil
Environments
Never install the amplifier in an environment containing dust or
oil mist. Dust and oil mist, which adheres to or accumulates on
the amplifier, will result in damage to the amplifier from lower
insulation resistance or leakage currents between conductors or
components.
Electrical Noise
Environments
Induction noise will enter input signals and the power supply
circuit, causing the amplifier to malfunction. When installing the
amplifier in an electrically noisy environment, take proper
measures such as inserting a noise filter, shielding, or suppressing
the noise source.
