Control Unit Connection
WARNING! The high voltage present in the high voltage cable which connects the control
unit to the ion pump, can cause severe injury or death. Before mounting the
high voltage connector of the cable on the pump high voltage feedthrough, or
before removing it, be sure the main power is removed from the control unit.
WARNING! To avoid injury, never connect the high voltage to the pump before it is
installed into the system and all the inlet flanges are properly connected or
blanked off. Make sure that the pump is well connected to the grounded
vacuum system.
WARNING! Before removing the high voltage connector of the cable from the control unit,
be sure the main power is removed from the control unit. Wait at least 10
seconds after removing the main power from the control unit, to allow
capacitors to discharge completely.
To disconnect the coaxial high voltage cable from the controller, slide
the safety locking sleeve (very little sleeve travel is required) from the
control unit and at the same time pull on the male end of the cable
connector to remove it from the socket on the control unit.
