Where mounted side by side
When installing SERVOPACKs side by side, provide at least 10 mm (0.4 in.) space between
them and at least 50 mm (2 in.) space above and below them as shown in the figure above.
Install cooling fans above the SERVOPACKs to prevent the temperature around each SER-
VOPACK from increasing excessively and also to maintain the temperature inside the con-
trol panel evenly.
Environments in Control Panel
Maintain the following conditions inside the control panel:
• Ambient temperature for SERVOPACK: 0 to 55
°
C
• Humidity: 90%RH or less
• Vibration: 4.9 m/s
2
• Condensation and freezing: None
• Ambient temperature to ensure long-term reliability: 45
°
C or less
• Altitude of 1000 m max.

Σ
-II series products to peripheral devices
and briefly explains how to connect each peripheral device.
For the following wiring, refer to
Σ
-II series SGM
H/SGDH User’s Manual (SIEPS80000005)
and
Σ
-II series SGDH Profibus-DP Application Module User’s Manual (SIE-C718-8).
• Main circuit wiring
• I/O signal wiring
• Encoder wiring
• Example of connections
• SERVOPACK grounding must be in accordance with the national code and consistent with
sound local practices.
Failure to observe this warning may lead to electric shock or fire.
• Do not connect three-phase power supply to SERVOPACK output terminals U, V, and W.
Failure to observe this caution may lead to personal injury or fire.
• Securely tighten screws on the power supply and motor output terminals.
Failure to observe this caution can result in a fire.
