Electrical Installation12.3.
WARNING!
Risk of injury due to electrical shock (120 V AC)!
When setting the position measuring system •
(Teach-In), do not contact any live components!
Before reaching into the system (except for the •
Teach-In procedure in a non-explosive atmosphere)
switch off the power supply and secure it to prevent
restarting
Observe applicable accident prevention and safety •
regulations for electrical equipment!
Risk of injury from improper installation!
the • PE connection must be connected!
Installation may be carried out by authorized techni-•
cians only and with the appropriate tools!
