CAUTION!
DANGER!
Replacement of the power cord plug may only be performed by
authorised personnel or a qualified electrician.
Make sure the power cord is not connected to any power source before
cutting off the power plug.
All alkitronic Electric Torque Multipliers are delivered with a three-wired
®
power cord with ground conductor. The housing or metal parts are
earthed by the
PE.
For avoidance of electric shocks or malfunctions
check the multiplier for electric safety after the power plug change.
Additional prerequisites for electric safety:
- Use only wall outlets with a protective earth connection (PE)!
- Make sure that the PE contact in the power socket is grounded!
- Use only a cord extension with an equipped ground conductor!
Incorrect connections of the supply line or outlet may lead to
electric shocks with deadly injuries.
