1. Application

In certain situations, floods can be live in electrical systems. This can happen, for example, if the water in

the basement rises above the level of the feed-in fuses and the power company fuses are not switched off

or through feed-in or storage devices from solar systems.

The MultiSafe DSP-HW 2 is a voltage warning device for the detection of dangerous voltages from

25 V AC / 40 V DC to 1000 V AC / 1500 V DC in water or similar conductive liquids.

The MultiSafe DSP-HW 2 is suitable for the following test tasks:

1.1 Testing of metallic banisters or other conductive objects

While approaching the flooded area, metallic banisters or other conductive objects that protrude into

the water can be checked for voltage.

1.2 Checking liquids for tension

At the edge of the flooded area, the water can be checked for voltage.
