3-1-4 Safety Reminders
After being transported, the unit may be very cold or hot. If this is the case, allow the unit to acclimate
before you turn it on. It requires one hour for each 2.5 Deg.C increment it’s temperature is below 10
Deg.C or above 40 Deg.C.
1.) All peripheral or accessory devices must be in conformance with their applicable standard for
safety. Computer devices must conform to IEC-EN 60950.
2.) The system of interconnected devices must conform to the leakage current requirements for
electrical medical equipment if any portion of the system is located within the patient vicinity (within
two meters of the patient).
3.) To achieve safe leakage current levels for equipment located within the patient vicinity, it may be
necessary to install data or mains isolation or additional protective earth conductors. Devices
having individual mains cords should always be connected to separate mains outlets. Multiple-
outlet extension boxes should not be used to power the LOGIQ™ 180 and the computer device
from a single mains plug.
4.) If safe leakage current levels are not achieved, the all parts of the system must be removed from
the patient vicinity before being interconnected. For example, the transfer of the images from the
LOGIQ™ 180 to a personal computer which exceeds safe current limits for medical electrical
equipment must be done only if both pieces of equipment are not located in the patient vicinity.
DANGER
WHEN USING ANY TEST INSTRUMENT THAT IS CAPABLE OF OPENING THE
AC GROUND LINE (I.E., METER’S GROUND SWITCH IS OPEN), DON’T TOUCH
THE UNIT!
CAUTION
Equipment damage possibility. Turning the system on without acclimation after arriving at site
may cause the system to be damaged.
Figure 3-7 Acclimation Time
CAUTION
To prevent electrical shock, connect the unit to a properly grounded power outlet. Do not use a
three to two prong adapter. This defeats safety grounding.
CAUTION
Electric shock hazard. The user is responsible to assure that, when peripherals or accessories
are interconnected with the LOGIQ™ 180 , the combination must conform to the requirements
of IEC/EN 60601-1-1 standard for safety of electrical medical systems. Leakage current safe
limits may be exceeded and serious injury may result if the following precautions are not
followed:
CAUTION
Do NOT wear the ESD wrist strap when you work on live circuits and more than 30 V peak is
present.
