If multiple portable socket outlets are used, they are subject to the following constraints:

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:
4
• 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.
• The Powerlab depends on the presence of a Protective Earth for electrical safety.
This is usually provided from the power outlet through a power cord but some
facilities may not have a safety earth available from the power outlet. Such
power outlets are identifiable by having only two connections on the power
outlet instead of three. If this is the case, a protective earth must be connected to
the PowerLab to ensure electrical safety. A suitable means of achieving this is to
use the Ground Connector (sometimes known as a POAG) mentioned in the Rear
Panel section of this Owner's Guide.
• If using the Ground Connector for protective earthing, the attached wire must
be cable of carrying the maximum current allowed by the circuit breaker and
must be electrically insulated. It must be connected to an equi-potential source
(a metal stake drive into the soil is a typical situation). A licensed electrician must
perform this installation.
• 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.
• PowerLabs are compatible with electrical safety devices (sometimes known as
Safety Switches, Ground fault circuit interruptor, Residual Current Devices or
Earth-leakage Circuit Breaker). ADInstruments recommends the use of such
devices supplied in fixed wiring installations.
• 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.
• When used in ambient temperatures of 38 degrees Celcius and above, do not
touch PowerLab enclosure continuously for more than a minute.
• To safely shut down the PowerLab, press the stop button and then close
LabChart. Turn the PowerLab off at the inlet switch.
• 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.
