Ground Connector; Power Connector; Checking And Replacing Fuses - ADInstruments POWERLAB TEACHING SERIES Owner's Manual

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 off ; 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:
