4. Installation
Another crucial factor to the performance of your SANDEX unit is the operating environment. Make an
early review of the location for your SANDEX unit and take any corrective actions necessary.
4.1 Casing main body
(1) Always use the lifting bolt holes provided on the housing of your SANDEX unit. Do not lift
the unit using the input or output shafts as this can affect the precision of the equipment, or
worse, affect the life of the machine.
(2) Each SANDEX unit has oil fill, drain and sight gauge ports. The unit should be mounted for
easy maintenance access to these ports.
(3) To ensure that your SANDEX unit is mounted accurately in the best possible position, make
sure the housing, shaft dimensions, and mounting holes comply with drawing specifications.
Also check the mounting area for perpendicularity and flatness. If the mounting surface has
any scratches, burrs, debris, or paint, use an oilstone or emery paper to remove it. Next,
clean the mounting surface and apply a light coat of grease or mineral oil to prevent rust
and scratches. You may now mount your SANDEX unit. Never install the unit in a position
not specified for your particular product.
(4) Align your peripheral equipment with the input and output shafts on the SANDEX unit to
ensure the best possible mounting position.
Apply Loctite 242 or equivalent screw locking solution to the mounting bolts, and tighten to
the specified torque with a torque wrench. (Tightening torque: DIN 8.8)
(5) The foundation for your SANDEX unit must be rigid enough to withstand vibrations from
other machines. The foundation is crucial to the precision and life of your SANDEX unit.
To ensure maximum performance mounts your SANDEX unit on a foundation that is
smooth, flat, hard, and free from vibration.
The standard operating temperature range for SANDEX units is between 0 to 40 degrees
Celsius (32 to 104°F). For usage outside of this range, follow the tips below.
4.2 Driver
The SGDH servo amplifiers are base-mounted. Incorrect installation will cause
problems. Follow the installation instructions below.
4.2.1 Storage Conditions
Store the servo amplifier within the following temperature range, as long as it is
stored with the power cable disconnected. -20 to 85°C (-4 to 185°F)
