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 four 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 Notes on Installation
When installed in a control panel • 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 sand provide sufficient
space around each SERVOPACK to allow cooling by fan
and natural convenction.
When installed near a heating unit 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
° C.
When installed near a source of
vibration Install a vibration isolator underneath the SERVOPACK to
prevent it from receiving vibration.
When installed in a place receiving
corrosive gases 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.
Others • 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.
