area of any moving part including
the load.
Otherwise, it may cause you to touch
the moving part and get injured.
⿟If the product fails or any abnor-
mality is observed, shut down the
power of the driver controller TSC.
Such abnormality may cause a
malfunction of actuator, resulting in
damage or injury.
⿟Do not touch the internal part of
the driver controller TSC.
Otherwise, it may cause electric shock.
⿟Do not damage, tuck, or apply
excessive stresses on the cable.
Otherwise, it may cause electric shock.
⿟Do not modify, disassemble, or
alter the product.
Otherwise, it may cause injury or
failures.

Otherwise, it may generate heat from
the internal parts of the driver controller
TSC, which results in fault or burns.
⿟Do not set the speed or
acceleration setting or place the
load on the table that exceed the
actuator specification.
Otherwise, it may cause motor failure,
which leads to unexpected accidents
or damages.
⿟If an alarm is generated, remove
the cause, check the safety, de-
activate the alarm, and restart the
operation.
Failure to do so may result in failure,
which leads to injury.
