Owner’s Guide 4
•
Do not touch the subject to which the PowerLab (or its peripherals) is connected
at the same time as making contact with parts of the PowerLab (or its peripherals)
that are not intended for contact to the subject.
•
Cleaning and sterilization of equipment should be performed in accordance
with manufacturer’s instructions. The isolation barrier may be compromised if
manufacturer’s cleaning instructions are not followed.
•
The ambient environment (such as the temperature and relative humidity) of the
system should be kept within the manufacturer’s specified range or the isolation
barrier may be compromised.
•
The entry of liquids into equipment may also compromise the isolation barrier. If
spillage occurs, the manufacturer of the aff ected equipment should be contacted
before using the equipment.
•
Many electrical systems (particularly those in metal enclosures) depend upon
the presence of a protective earth for electrical safety. This is generally provided
from the power outlet through a power cord, but may also be supplied as a
dedicated safety earth conductor. Power cords should never be modified so as
to remove the earth connection. The integrity of the protective earth connection
between each piece of equipment and the protective earth should be verified
regularly by qualified personnel.
•
Avoid using multiple portable socket-outlets (such as power boards) where
possible as they provide an inherently less safe environment with respect to
electrical hazards. Individual connection of each piece of equipment to fixed
mains socket-outlets is the preferred means of connection.
If multiple portable socket outlets are used, they are subject to the following constraints:
•
They shall not be placed on the floor.
•
Additional multiple portable socket outlets or extension cords shall not be
connected to the system.
•
They shall only be used for supplying power to equipment which is intended to
form part of the system.
Bio Amp Safety Instructions
The Bio Amp inputs displaying any of the safety symbols are electrically isolated from
the mains supply in order to prevent current flow that may otherwise result in injury to
the subject. Several points must be observed for safe operation of the Bio Amp:
•
All Bio Amp front-ends (except for the FE234 Quad and FE238 Octal Bio Amps)
and all PowerLab units with a built-in Bio Amp are supplied with a 3-lead or
5-lead Bio Amp subject cable and lead wire system. The FE234 Quad and FE238
Octal Bio Amps are supplied with unshielded lead wires (1.8 m). Bio Amps are
only safe for human connection if used with the supplied subject cable and lead
wires.
•
Bio Amp front-ends are NOT defibrillator-protected. Using the Bio Amp to record
signals during defibrillator discharges may damage the input stages of the
amplifiers. This may result in a safety hazard.
•
Never use damaged Bio Amp cables or leads. Damaged cables and leads must
always be replaced before any connection to humans is made
.
