Installation General environmental conditions

When installing the servo motor horizontally, face the power cable and encoder cable
downward. When installing the servo motor vertically, lay the cables with an adequate cable trap
to avoid mechanical load on the cable and motor.
Make sure that the cables leading to the servo motor does not pass through oil or water. Due to
the effects of capillarity, oil or water could get into the motor via the cables.
When the servo motor is to be installed with the shaft end at top, provide measures so that it is
not exposed to oil and water entering from the machine side, gear box, etc.
