E-Compact Medium Power 

4.4. AC Electrical Line Connection 

 

Prior to energizing the transmitter, one must make sure that the circuit breaker and 

the power switch (ON / OFF) are switched off or disabled.. 

 

4.4.1.  Electrical line connection (EC70xMP)

 

 

The Electrical Line is connected to the AC Unit: 
 
 

 

Before Connecting the Machine to the AC Mains, one must ensure that the grid 

Voltage meets the equipment’s settings. Any questions, please refer to Section 3 

item 6.7. “AC Mains Protection Unit” of this manual. 

 

Connection modes according to the Grid Voltage: 

 

 
 
 
 
 
 
 
 
 
 
 
 
 
 

 

Never invert Neutral with Phase. 

 

 

The screws must be properly tightened in order to avoid sparks.
