Outline Notes
1. The mounting flange is the connection for the
cathode, cathode heater return and reservoir
heater return.
2. A minimum clearance of 25.4 mm (1.000 inch)
must be allowed below the mounting flange.
3. Where e2v technologies gives prior agreement
to the use of alternative lead/mounting ar-
rangements on these posts, great care must be
taken to avoid damaging the threads and the
metal/ceramic joints. A flat wrench must be
used to hold the nut nearest the ceramic while
a torque wrench, set to a value of less than
0.046 kg-m (4 lb-in), is used on the other nut.
