Terminal block wiring: Failure to follow the instructions below could result in 
equipment damage and may result in hazardous conditions such as fire or 
shock and could lead to personal injury or death.
Wiring of the terminal block must be performed by qualified persons. A 
MAXIMUM of 5 mm of conductor insulation is to be removed. All wire 
strands must be appropriately inserted in the connector housing. The screw 
connections must be sufficiently secured to prevent accidental loosening. 
Never operate the instrument without the terminal block covers securely 
installed. Use caution to prevent operators from accessing any external 
circuits, test fixtures, cables or whenever hazardous voltages may be 
present.
