Ground Connector
A special earthing (grounding) stud is provided on the rear panel of the PowerLab. This
is an equipotential bonding connection post compatible with the DIN 42801 standard.
The earthing stud is directly connected to the earth pin of the power socket and the
PowerLab chassis. It is used as a primary earth connection (equipotential connection
point) in situations that require this type of connection, or if there is no ground provided
via the power cord. Safety standards in laboratories and similar environments may
require additional grounding protection when connecting equipment to human
subjects, and their relevant standards or guidelines should be observed.
Power Connector
The power switch on the back right of the PowerLab turns the PowerLab on and o ; the
3-pin IEC power socket is used to connect your PowerLab to a power cable. The power
supply is universal, and can use all common international mains power supplies (100–
240 V AC, 50/60 Hz).
The PowerLabs are now fitted with replaceable fuses. If the Power LED on the PowerLab,
does not illuminate with power applied, it may be that one or both of the replaceable
fuses has blown.Fuses should only be of the rating and type as specified below:
• 250VAC Slo Blo (usually marked “T”)
• 1A
• 20 x 5mm
Checking and replacing fuses
Ensure the power lead is disconnected before attempting to replace a fuse.
The fuses are contained in the fuse drawer. To remove the drawer, the top and bottom
plastic tabs need to be squeezed simultaneously while pulling the drawer away from
the PowerLab (a small flat-bladed tool is useful for this task). The old fuses should spring
free of the drawer once removed from the inlet. Load the new fuses back into the drawer
and carefully push back into the inlet. Note that the fuse drawer is polarized and can
only be put back in one orientation. For further assistance please contact your nearest
ADInstruments representative
