Notices on handling
Handle the SHA series actuator carefully by observing the notices specified below.
（
1
）
Do not apply any excessive force or impact, especially to the actuator's
output shaft.
（
2
）
Do not put the SHA series actuator on a table, shelf, etc., where the
actuator could easily fall.
（
3
）
Do not connect the actuator terminals directly to the power supply. The
actuator may burn and cause fire or electric shock.
（
4
）
The allowable storage temperature is -20 to +60
℃
. Do not expose the
actuator to direct sunlight for long periods of time or store it in areas in
low or high temperature.
（
5
）
The allowable relative storage humidity is 80% or less. Do not store the
actuator in a very humid place or in areas where temperatures are likely to
fluctuate greatly during day and night.
（
6
）
Do not use or store the actuator in locations subject to flammable or
corrosive gases or dust particles.
（
7
）
The large models (SHA58A, SHA65A) are heavy. Handling these models
may cause lower back pain. Injury may occur if the actuator falls and you
are pinned underneath. Handle your actuator with due care by wearing
safety shoes or take other proper precautions. Use supporting fixtures
and lifting equipment as necessary for safe handling.
Installation and transmission torque
Examples of actuator assembly are shown below. Assembly examples 1 and 2 are for SHA-SG.
Assembly examples 3 and 4 are for SHA-CG. Use high-tension bolts and tighten them with a torque
wrench to control the tightening torque. In assembly example 2, use flat washers because the
tightening torque is high and the actuator flange is made of aluminum.
