Instructions on the operation of protective untriggered gap Ð-79:
-
While operating protective untriggered gap Ð-79 parameter points shouldn't overrate the admissible values.
-
On-position of protective untriggered gap – any position.
-
Cooling down – natural cooling.
-
Protective untriggered gap Ð-79 is fixed in the device on the cathode flange with the help of 4 screws M3.
We recommend to joint to the anode of the gap with the help of a screw using the hole on the anode button.
-
While binding and connecting of the gap in the device the power used shouldn't lead to the curve of button.
