12.3. Electrical Installation
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!
