2.3.2 Installation Standards
Observe the standards for mounting SERVOPACKs in control panels, including those
for the mounting SERVOPACKs side by side in one control panel as shown in the
following illustration.
• SERVOPACK Mounting Orientation
Mount the SERVOPACK vertically to the wall, with the front panel facing out.
• Cooling
Refer to the following diagram and leave sufficient space for cooling by fans and nat-
ural convection.
• Mounting SERVOPACKs Side by Side in a Control Panel
∗ Mounting differs with cooling method.
Leave sufficient space on each side and at the top and the bottom of each SERVO-
PACK. Space between SERVOPACKs differs with the cooling method as shown in
the following table.
∗ When the space between SERVOPACKs is less than 10 mm, select fans that will circulate air
at a wind velocity of 0.2 m/s or more when a wind gauge is installed 10 mm away from the
bottom of the SERVOPACK.
• Inside the Control Panel
The conditions inside the control panel should be the same as the environmental con-
ditions of the SERVOPACK. Refer to
2.1.2 SERVOPACK Installation Environment .
