Power and Static
WARNING
CAUTION
WARNING
Disconnect power from the leak detector before
performing any maintenance procedure that requires
physically disconnecting any part of the system.
Many components of the leak detector are
static-sensitive devices. Varian Vacuum Technologies
recommends that you wear a grounding device when
performing any maintenance on the leak detector and
especially when performing maintenance of
static-sensitive parts.
Electrical insulation must include the appropriate
branch circuit (at least 20 A), with long time delay and a
reliable earth ground. Do not use an extension cord.
Use only the power cord that was provided with your
leak detector. The use of extension cords is not
recommended and could result in damage to the
equipment and loss of warranty.
To avoid electric shock, connect the product power
cord to a grounded power receptacle. A protective
ground connection by way of the grounding conductor
in the power cord is essential for safe operation.
Before powering up the leak detector for the first time,
verify that the leak detector is configured to operate
from the local mains supply voltage.
Opening the enclosure may expose hazardous voltages.
Always disconnect the power cord and any interface
cables before opening the enclosure. Do not touch the
power inlet's contacts for at least 10 seconds after
disconnecting the power cord.
