1-4 Installation of the drive unit
1-4-1 Environmental conditions
(Note) When installing the machine at 1,000m or more above sea level, the heat dissipation
characteristics will drop as the altitude increases.
The upper limit of the ambient temperature drops 1°C with every 100m increase in altitude.
(The ambient temperature at an altitude of 2,000m is between 0 and +45°C.)
1. Install the unit on noncombustible material. Direct installation on combustible material or near
combustible materials may lead to fires.
2. Follow the instructions in this manual and install the unit while allowing for the unit mass.
3. Do not get on top of the units or motor, or place heavy objects on the unit.
Failure to observe this could lead to injuries.
4. Always use the unit within the designated environment conditions.
5. Do not let conductive objects such as screws or metal chips, etc., or combustible materials such as
oil enter the units.
6. Do not block the units intake and outtake ports. Doing so could lead to failure.
7. The units and servomotor are precision devices, so do not drop them or apply strong impacts to
them.
8. Do not install or run units or servomotor that is damaged or missing parts.
9. When storing for a long time, please contact your dealer.
10. Always observe the installation directions. Failure to observe this could lead to faults.
11. Secure the specified distance between the units and panel, or between the units and other
devices. Failure to observe this could lead to faults.
