XTC/3 Operating Manual
2.1.3 XTC/3 Installation
XTC/3 is designed to be rack mounted with the optional rack mount kit
(PN 780-702-G1). It may be also used on a table. A two-unit rack mount option kit
(PN 780-702-G2) is available for mounting two XTC/3 side by side.
Centrally locate the controller to minimize the length of external cabling.
2.2 Avoiding Electrical Interference
Careful consideration of simple electrical guidelines during installation will avoid
many problems caused by electrical noise.
To maintain the required shielding and internal grounding and ensure safe and
proper operation, XTC/3 must be operated with all enclosure covers, sub-panels,
and braces in place and fully secured with the screws and fasteners provided.
NOTE:
When using XTC/3 with an RF sputtering system, the cable between
XTC/3 and oscillator should be kept as far away from the RF transmission
cable as possible. Interference from the RF transmission cable may cause
an erroneous crystal fail.
2.2.1 Verifying/Establishing Earth Ground
If a ground must be established, the following procedure is recommended:
Where soil conditions allow, drive two ten foot copper clad steel rods into the
ground six feet apart. Pour a copper sulfate or a salt solution around to improve
the ground’s conduction. A near zero resistance measurement indicates earth
ground is achieved.
Keep connections to this grounding network as short as possible.
