4.2 SERVOPACK Installation
4-7
4
Orientation
Install the SERVOPACK perpendicular to the wall as shown in the figure. The SERVOPACK must be oriented
this way because it is designed to be cooled by natural convection or a cooling fan.
Secure the SERVOPACK using two to four mounting holes. The number of holes depends on the capacity.
Installation
Follow the procedure below to install multiple SERVOPACKs side by side in a control panel.
SERVOPACK Orientation
Install the SERVOPACK perpendicular to the wall so the front panel containing connectors faces outward.
Cooling
As shown in the figure above, allow sufficient space around each SERVOPACK for cooling by cooling fans
or natural convection.
Side-by-side Installation
When installing SERVOPACKs side by side as shown in the figure above, allow at least 10 mm (0.39 in)
between and at least 50 mm (1.97 in) above and below each SERVOPACK. Install cooling fans above the
SERVOPACKs to avoid excessive temperature rise and to maintain even temperature inside the control
panel.
Environmental Conditions in the Control Panel
Ambient Temperature:0 to 55°C (32 to 131° F)
Humidity: 90% RH or less
Vibration: 4.9 m/s
2
Condensation and Freezing: None
Ambient Temperature for Long-term Reliability: 45 °C (113 °F) or less
Voltage
Resistance Test
Conduct voltage resistance tests under the following conditions.
• Voltage: 1500 Vrms AC for one minute
• Braking current: 30 mA or more
• Frequency: 50 or 60 Hz
• Voltage applied points
For SGDM-AD, -ADA SERVOPACKs : Between the ground terminals and the point where the ter-
minals L1, L2, (L3), L1C, L2C, U, V, W are connected.
For SGDM-BD, -BDA SERVOPACKs : Between the ground terminals and the point where the ter-
minals L1, L2, (L3), L1C, L2C, U, V, W are connected.
