Installation Sites - YASKAWA E-III Series Safety Precautions

9 Installation
Observe the following precautions when installing SERVOPACK.
• Install SERVOPACK perpendicular to the wall so that the front panel (digital operator
mounted face) faces outward.
• Firmly secure the SERVOPACK through two or three mounting holes depending on the
SERVOPACK capacity.
• Install SERVOPACK so that SERVOPACK can be cooled by natural convection or fan.

Installation Sites

For installation sites, use proper care with the following notes.
Situation
When installed in a control panel
When installed near a heating unit
When installed near a source of
vibration
When installed in a place receiving
corrosive gases
Others
Cooling fan
30 mm (1.2 in.) or more
• Design the control panel size, unit layout, and cooling
method so that the temperature around the periphery of the
SERVOPACK does not exceed 55°C.
• When installing multiple SERVOPACKs side by side in a
control panel, install cooling fans and provide sufficient
space around each SERVOPACK to allow cooling by fan
and natural convection.
Suppress radiation heat from the heating unit and a tempera-
ture rise caused by convection so that the temperature around
the periphery of the SERVOPACK does not exceed 55
Install a vibration isolator underneath the SERVOPACK to
prevent it from receiving vibration.
Corrosive gases do not immediately affect the SERVOPACK
but will eventually cause contactor-related devices to malfunc-
tion. Take appropriate action to protect against corrosive gases.
• Avoid installation in a hot and humid place or where exces-
sive dust or iron powder is present in the air.
• Be sure there is no condensation or freezing.
• Keep the surrounding air temperature 45 °C or less to ensure
long-term reliability.
