Cautions on Mounting
Design the control panel size, digital torque amplifier
installation, and cooling method so that the ambient
temperature of the digital torque amplifier does not exceed
55 .

Suppress the temperature rise due to radiated heat and
convection from the heat-generating object so that the
ambient temperature of the digital torque amplifier does
not exceed 55 .
°C
Attach vibration-preventative brackets to the digital torque
amplifier mounting surface so that the vibrations are not
communicated to the digital torque amplifier.
