General Information
Safety Information
The supplied power cord must be inserted into a power outlet with a
protective earth contact (ground). When using an extension cord, make sure
that the cord also has an earth contact.
Do not change the external or internal grounding connections. Tampering
with or disconnecting these connections could endanger you and/or damage
the LC Injector HTC/HTS System.
The instrument is properly grounded in accordance with these regulations
when shipped. You do not need to make any changes to the electrical
connections or the instrument's chassis to ensure safe operation.
The combination of a LC Injector HTC/HTS System with a LC/MS System does
require the safety measure as described by the LC/MS System manufacturer.
Detailed instructions for the safety grounding on the LC/MS system are
outlined in the corresponding operating/installation manual.
Agilent Technologies recommends to use a grounding cable connected on one
side at the Injection Valve, Loop or any other suitable direct metallic contact
and the other side at an appropriate grounding point at the LC/MS System.
This supplementary grounding measure will support the safety strategy of the
LC/MS System manufacturer.
Do not turn the instrument on if you suspect that it has incurred any kind of
electrical damage. Instead disconnect the power cord and contact a Agilent
Technologies representative for a product evaluation. Do not attempt to use
the instrument until it has been evaluated. Electrical damage may have
occurred if the LC Injector HTC/HTS System shows visible signs of damage,
exposure to any liquids or has been transported under severe stress.
Damage can also result if the instrument is stored for prolonged periods under
unfavorable conditions (e.g. subjected to heat, water, etc.).
