Ensure the lead is connected to a wall power outlet and
not
to
another
extension 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 or accessory, 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 (when used)
Warning!
Do not use adapter plugs that bypass the grounding feature, or remove the
grounding feature from the plug or adapter.
Place the AC adapter in a ventilated area, such as a desk top or on the floor.
The AC adapter may become hot during normal operation. Take care when
handling the adapter during or immediately after operation.
Use only the Malvern-provided AC adapter approved for use with the instru-
ment and/or accessory. Using another AC adapter may cause a fire or explo-
sion.
Advice on use of Uninterruptible Power Supplies (UPS)
To help protect the instrument and/or accessory from sudden, transient
increases/decreases in electrical power, use a surge suppressor, line conditioner
or UPS.
