B. Regulatory and Safety
Electrical hazards
Every laboratory instrument has specific hazards, so be sure to
read and comply with the following precautions. They will help
to ensure the safe, long-term use of the sample preparation
extractor.
Only use fuses of the type and current rating specified. Do not
use repaired fuses and do not short-circuit the fuse holder. It is
considered to be best practice to use a power supply protected
by RCD trips.
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.
It is recommended that the XTRX500 external power supply
(power brick) is placed away from any area where organic vapor
can collect in levels that could cause a potential explosion.
Do not change the external or internal grounding connections.
Tampering with or disconnecting these connections could
endanger life and/or damage the sample preparation extractor.
The instrument is properly grounded in accordance with these
regulations when shipped. No changes to the electrical
connections or the instrument's chassis are required to ensure
safe operation.
Do not turn the instrument on if any kind of electrical damage is
suspected. Instead disconnect the power cord and contact a
Teledyne Hanson representative for a product evaluation. Do
not attempt to use the instrument until it has been evaluated.
Electrical damage may have occurred if the sample preparation
extractor 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.).
In any case, disconnect the power cord(s) from the power
supply or from the different power supplies if optional devices
are installed before attempting any type of maintenance.
