WARNING
When using a leakage beaker as the primary power switch, use one that
supports high harmonics.
Malfunctions can occur with switches that do not support high-harmonics.
Primary power supply connections
The chamber is connected to the primary power supply via the power cable. It is also
grounded to prevent noise from infiltrating electronic circuits and to protect users
against electric shock which can result from leakage current.
WARNING
EXPLOSION! DO NOT ground the equipment on gas pipes.
Grounding of the sort could result in explosion.
DO NOT share ground with equipment not fitted with a leakage breaker.
The chamber's leakage breaker will not trip in the event of overcurrent,
short-circuits or surges.
DO NOT ground between equipment.
The chamber's leakage breaker will not trip in the event of overcurrent,
short-circuits or surges.
Ground the equipment WITHOUT FAIL
Unless the equipment is grounded, the leakage breaker will not trip in the event
current leaks, possibly resulting in electric shock. Furthermore, this will leave the
equipment unprotected against power supply noise. Sometimes, the temperature
(humidity) in the chamber can be destabilized.
