CAUTION
If the intake air/exhaust spaces described above are not secured, the motor and controller will
reach high temperatures and the lives of the devices will be significantly shortened. Be sure
to secure the space for air intake /exhaust.
If the intake air/exhaust spaces described above are not secured, the motor and controller will
reach high temperatures, temperature protection will be actuated and the product will stop
running.
Continuing to use the product while it is at a high temperature will result in trouble affecting,
and shorten the lives of, the electrical components as described previously, but also hydraulic
devices such as pumps and valves. It will also promote deterioration of the hydraulic oil,
shortening the service life of the oil.
7.2.2 Securing the hydraulic unit
Secure the hydraulic unit either on a level platform or level floor, that will not be affected by the vibration
of the main machine (M10 bolts at 4 locations). For details on the mounting method and position, refer to
the Delivery Specification (outside drawing).
WARNING
If the hydraulic unit is not secured, it may topple over or move as a result of reactions to the
hydraulic pressure in the piping and so on, imposing a hazard. Be sure to secure it with bolts,
etc.
CAUTION
Installing the product on a sloping surface may cause oil leakage and inclusion of air in the
oil, leading to abnormal noises and shortening of equipment life. Be sure to install it on a
level surface.
