Symbol Description
Protective conductor terminal (main ground). It must be connected to earth ground
before any other electrical connections are made to the instrument or system.
To minimize negative environmental impact from disposal of electronic waste, do not
dispose of electronic waste in unsorted municipal waste.
Follow local municipal waste ordinances for proper disposal provision. Contact customer
service for information about responsible disposal options.
Electrical Safety
WARNING ELECTRICAL HAZARD. DO NOT REMOVE THE COVERS. Electrical
shock can result if the system is operated without its protective covers. No internal
components under the covers are serviceable by the user.
WARNING ELECTRICAL HAZARD. Plug the system into a properly grounded
receptacle with adequate current capacity.
WARNING Lethal voltages are present at certain areas within the system. Only a
Fluidigm field service engineer or those similarly authorized and trained by
Fluidigm personnel should install or repair the system.
WARNING The interface and backing pumps in the system are in close proximity
to areas where high voltages are present. User access to the pumps is not advised.
Only Helios™ operators trained by Fluidigm may access the pump compartment
and change the interface pump oil. Disengage the radio frequency generator
circuit breaker on the right side of the system before accessing this area.
WARNING Do not touch electrical wires, contacts, transformers, or transformer
components during the oil inspection procedure (see the user guide). A metal
shield located in the system compartment above the interface pump contains the
transformers and electrical wires. There is no need to access this section when
servicing the pumps.
•
When the system is connected to line power, opening system covers is likely to
expose live electrical parts.
•
High voltage can still be present even when the radio frequency generator power
switch is off.
•
Water lines should be located away from electrical connections. Condensatio
n
and p
otential leaks may create an unsafe environment in the proximity of
electrical connections.
WARNING Before performing maintenance on the cones or torch, switch off the
radio frequency generator power using the circuit breaker at the right rear of the
system. Wait at least 5 minutes for residual electrical charge to dissipate. Additional
time is required to allow the inductively coupled plasma torch, cones, and load coil
to reach room temperature.
•
Capacitors inside the system may still be charged even if the system has been
di
sconnected from all voltage sources.
•
The system must be correctly connected to a suitable electrical supply (see th
e
site requirements guide for further details).
