Make sure that the personnel has read the operating manual and understood all instructions relating to safety.
Scope of delivery
1 x PEM353, 1 x rubber seal, 4 x retaining clips, 1 x safety instructions
for Bender products (multilingual), 1 x quick-start guide
Intended use
The PEM353 is suitable for use in 2-, 3- and 4-wire systems and in their respective versions as TN, TT and IT
systems. The current measurement inputs of the PEM353 are always connected via external …/1A or …/5A
measuring current transformers. In principle, measurements in medium and high-voltage systems are carried out via voltage transformers.
Use for the intended purpose also includes:
Device-specific settings compliant with local equipment and operating conditions
Adhering to the manual
Any other use than that described in this manual is regarded as improper.
Safety instructions
Risk of fatal injury due to electric shock!
Touching live parts of the system carries the risk of an electric shock, damage to the electrical installation
or destruction of the device.
Before installing and connecting the device, make sure that the installation has been de-energised.
Observe the rules for working on electrical installations.
Refer to the rated and supply voltage values as specified in the technical data!
