3.10 Connecting the Gauge Cables
3.10.1 Convectron Gauge Cable Installation
If you have Convectron Gauge capability, connect a Convectron Gauge cable between the Control
Unit and each gauge.
Be aware that an electrical discharge through a gas may couple dangerous
high voltage directly to an ungrounded conductor almost as effectively as
would a copper wire connection. A person may be seriously injured or even
killed by merely touching an exposed ungrounded conductor at high
potential.
This hazard is not unique to this product.
Be aware that when high voltage is present in any vacuum system, a life
threatening electrical shock hazard may exist unless all exposed conductors
are maintained at earth ground.
This hazard is not peculiar to this product.
All conductors in, on, or around the vacuum system that are exposed to
potential high voltage electrical discharges must either be shielded at all
times to protect personnel or must be connected to earth ground at all times.
Never touch the connector pins on any vacuum gauge if high voltages are
present in the vacuum system. An electrical discharge or plasma may
couple high voltage to the pins.

Warning – If used improperly, Convectron Gauges can supply misleading
pressure indications that can result in dangerous overpressure conditions
within the system. For use with gases other than air or N
2
, consult the gas
type correction charts in Section 4.7.1 on page 4-19, or use a Memory
Module programmed with data for the specific gas being used.
