– Lamp: body contacts can be simulated by connectable

resistors 2.2; one

Transformer

– The transformer can be used as a low-voltage transformer,

an auto-transformer, an isolating transformer, and a summation

current transformer.

Earth contact, auxiliary earth contact

– With the measuring points for voltage measurement at

1 / 2 / 5 / 10 / 20 m

Mechanical Data

The front panel of the SAFETY BOARD is made of 5 mm thick

Laminate, matt blue in color with white engraving representing

the built-in function groups.

The rear of the Board is protected with a gray plastic cover.

Its shape allows the Board to be placed at an ergonomically favorable

angle for example on a table.
