Electrical Safety
The following are the precautions that should be observed when combining these items (non-medical equipment) with the system.
•
Items that do not meet the
requirements of standard IEC 60601-1
cannot be placed within 1.5 from the
patient.
•
All items (electromedical or non-
medical equipment) connected to the
system with input/output signal cable
must receive power from an AC source
using separate transformer (according
to standard IEC 60989) or provide
additional earth protective conductor.
•
Multiple portable sockets with switch
used on AC power supplies must
comply with IEC 60601-1-1 and cannot
be installed on the floor. Do not use
more than one power strip with
portable switch.
•
Do not connect directly the non-
medical electrical equipment to an AC
wall outlet. Use AC power supply with
its own transformer. Otherwise, the
leakage current will increase above the
levels accepted by IEC 60601- under
normal conditions and single-failure
conditions. This may cause dangerous
electrical shock to the patient or
operator.
•
After connecting any equipment into
these outlets, the system should
undergo a complete test for leakage
current (according to standard IEC
60601-1).
•
The operator of the electromedical
system must not touch the non-
medical electrical equipment and the
patient at the same time. This may
cause dangerous electrical shock to
the patient or operator.
