Servicing and conversion work
Risk of personal injury through incorrect
operation, use or installation as a result of
incorrect information on the actuator.
After any adjustment or conversion work, the
details on the actuator nameplate may no
longer be correct. This may apply, for exam‑
ple, to the configuration ID or the symbol af‑
ter reversal of the direction of action.
Î
Immediately renew any nameplates or
labels with incorrect or outdated infor‑
mation.

Add any new values to the nameplate. If
necessary, contact SAMSON to obtain a
new nameplate.

actuator components. Excessively tightened
torques lead to parts wearing out quicker.

loosen.
