Installation direction and clearances
CAUTION
The devices must be installed in the specified direction. Not doing so may cause
a malfunction.
Mount the servo amplifier on a cabinet which meets IP54 in the correct vertical
direction to maintain pollution degree 2.
Note the followings for supplied regenerative resistors of 11 kW to 22 kW servo
amplifiers because they do not have protect covers.
Touching the resistor will cause a burn because the surface of the parts is a
resistive element and very high temperature.
Even if the power turned off, touching the resistor will cause an electric shock
because the capacitor of the servo amplifier is charged for a while.
