G5-series AC Servomotors and Servo Drives User’s Manual (with Built-in EtherCAT Communications)
4-1 Installation Conditions
• Install the Servo Drives according to the dimensions shown in the following illustration to ensure
proper dispersion of heat from inside the drives and convection inside the panel. If the drives are
installed side by side, install a fan for air circulation to prevent uneven temperatures inside the panel.
• However, W is 50 mm min. when a Servo Drive of 7.5 kW or 15 kW is installed.
• Drives of 100 V or 200 V with a capacity of 750 W max. can be installed side by side with a 1-mm
clearance (W in above illustration).
• To provide electrical conduction, remove any paint from the surface on which you are installing G5-
series Servo Drives.
Also, it is recommended that you apply conductive plating if you are making the mounting bracket
yourself.
• Mount the drive perpendicular on the panel so that the model number reads normally.
• The environment in which drives are operated must meet the following conditions. Drives may
malfunction if operated under any other conditions.
Ambient operating temperature: 0 to 55°C (Take into account the following temperature rises in the
individual drives themselves.)
Operating humidity: 90% max. (with no condensation)
Operating atmosphere: No corrosive gases.
Altitude: 1,000 m max.
• For Drives of 100 V or 200 V with a capacity of 750 W max., the specifications for operating ambient
temperature depend on the Drive (A, B, and C) when the clearance between Drives is 1 mm.
