DANGER
Electric shock
Death or serious personal injury
- Switch off the power supply to the motor
and to the signal relay. Wait at least 5
minutes before starting any work on the
motor. Make sure that the power supply
cannot be accidentally switched on.
Always use an antistatic service kit when
handling electronic components. This
prevents static electricity from damaging
the components.
When unprotected, place the component
on the antistatic cloth.
