2.2 Servo Amplifiers
The SGDH servo amplifiers are base-mounted servoamps. Incorrect installation will
cause problems. Follow the installation instructions below.
2.2.1 Storage Conditions
Store the servo amplifier within the following temperature range, as long as it is
stored with the power cable disconnected.
-20 to 85°C
2.2.2 Installation Site
The following precautions apply to the installation site.
Situation Installation Precaution
Installation in a Control
Panel
Design the control panel size, unit layout, and cooling
method so the temperature around the servo amplifier
does not exceed 55°C.
Installation Near a
Heating Unit
Minimize heat radiated from the heating unit as well as
any temperature rise caused by natural convection so
the temperature around the servo amplifier does not
exceed 55°C.
Installation Near a
Source of Vibration
Install a vibration isolator beneath the servo amplifier to
avoid subjecting it to vibration.
Installation at a Site
Exposed to Corrosive
Gas
Corrosive gas does not have an immediate effect on the
servo amplifier, but will eventually cause electronic
components and contactor-related devices to malfunc-
tion. Take appropriate action to avoid corrosive gas.
Other Situations
Do not install the servo amplifier in hot and humid
locations or locations subject to excessive dust or iron
powder in the air.
