Getting Started
22 Agilent Vapor Generation Accessory VGA 77 and VGA 77P User’s Guide
The indicator light is the single blue light on the top panel of the
accessory. If the indicator light turns on, switch the VGA 77 off
immediately, rectify the gas supply problem, then switch the VGA 77
back on. If the indicator light again turns on, you should call your
Agilent field service engineer.
CAUTION
Respond quickly to no or low gas pressure or flow errors indicated by the blue
light. Failure to do so can damage the VGA due to acid or vapor ingression
caused by insufficient gas supply flow.
Power Supply Requirements
The voltage selector, mains receptacle, power switch and fuses are
located on the right-hand side of the accessory.
Before connecting the mains power for the first time, check that the
correct power supply is available, the voltage selector switches on the
accessory are set correctly, and that the correct fuses are installed
and both fuses are of the same rating.
WARNING
Shock and Fire Hazard
Application of the wrong supply voltage, connection of the accessory to an
incorrectly wired supply outlet, or lack of proper electrical grounding can
create a fire or shock hazard that can cause death, serious injury or serious
damage to equipment.
For power supply and fuse specifications refer to the ‘Specifications’
section in Section 2 of this manual. Refer to the ‘Fuses’ section in the
Maintenance chapter of this manual for details of how to inspect and
replace fuses.
