Power safety
The notes in this section indicate best practice and should be adhered to when con-
necting the instrument to the power supply.
Power safety information
The following notes indicate guidelines to follow when connecting the Malvern
Instruments power supply using single and multiple extension leads, connection
via AC Adapters and use of Uninterruptible Power Supplies (UPS).
Warning!
To prevent electric shock, plug the instrument into correctly earthed elec-
trical outlets.
The power cord supplied is equipped with a grounding connection to ensure
grounding integrity is maintained.
Advice on use of Extension leads
Follow this advice when using single or multiple socket extension leads. These are
also called “trailing sockets”.
„
Ensure the lead is connected to a wall power outlet and not to another exten-
sion lead. The extension lead must be designed for grounding plugs and
plugged into a grounded wall outlet.
„
Ensure that the total ampere rating of the products being plugged into the
extension lead does not exceed the ampere rating of the extension lead.
„
Use caution when plugging a power cord into a multiple socket extension lead.
Some extension leads may allow a plug to be inserted incorrectly.
„
Incorrect insertion of the power plug could result in permanent damage to the
instrument, as well as risk of electric shock and/or fire. Ensure that the ground
connection (prong/pin) of the power cord plug is inserted into the mating
ground contact of the extension lead
Advice on use of AC adapters
Follow this advice when using AC adapters:
Warning!
Do not use adapter plugs that bypass the grounding feature, or remove the
grounding feature from the plug or adapter.
