3.4 Auxiliary Mains Supply (L & N)
The MultiCube uses an isolated auxiliary mains supply separate from the voltage
measurement input. This may be connected separately or in parallel with the
measurement inputs provided the ratings detailed on the instrument label are not
exceeded.
Separate connection of the auxiliary mains is required, for example, when :
•
A suitable supply voltage is not available locally.
•
Measurement voltages are expected to vary over a wide range
•
A backup supply is required to maintain meter display
External fusing is required for safe installation. The external fuse should be rated at
250V, 100mA Type T.
WARNING :
CHECK
the instrument
LABELS
for correct input ratings.
Incorrectly rated inputs may permanently damage the device
NOTE:
The MultiCube may be supplied with a non-standard auxiliary mains supply
type (eg 72V DC). In this case separate documentation will be available, providing
specific installation/safety information.
