Input A (L1), B (L2), C (L3), N to Ground: 1000 V CAT III, 600 V CAT IV.
Input A (L1), B (L2), C (L3), N to Ground: 42 V peak.
Voltage ratings are given as "working voltage". They should be read as V ac rms
(50-60 Hz) for AC sinewave applications and as V dc for DC applications.

Use only correct measurement category (CAT), voltage, and
amperage rated probes, test leads, and adapters for the
measurement.
Do not exceed the Measurement Category (CAT) rating of the
lowest rated individual component of a product, probe, or
accessory.
Comply with local and national safety codes. Use personal
protective equipment (approved rubber gloves, face
protection, and flame resistant clothes) to prevent shock and
arc blast injury where hazardous live conductors are exposed.
The battery door must be closed and locked before you
operate the product.
Do not operate the product with covers removed or the case
open. Hazardous voltage exposure is possible.
Take special care during fitting and removal of the flexible
current probe: de-energize the installation under test or wear
suitable protective clothing.
Do not use exposed metal BNC or banana plug connectors.
Do not insert metal objects into connectors.
Use only the power supply, Model BC430 (Power Adapter).
Before use check that the selected/indicated voltage range on
the BC430 matches the local line power voltage and frequency
(refer to figure below). If necessary set the slider switch of the
BC430 to the correct voltage.
For the BC430 use only AC line plug adapters or AC line cords
that comply with local safety regulations.
Remove the input signals before you clean the product.
Use only specified replacement parts.
Slider switch on Power Adapter to select line power voltage (Note: for Adapters without
slider switch, refer to Instruction Sheet as supplied with device):
