1.7 Disposal
Abide by the national regulations and laws governing the disposal of this device. Ask
your supplier if you are not sure how to dispose of the old equipment.
The directive on waste electrical and electronic equipment (WEEE directive) and the di-
rective on the restriction of certain hazardous substances in electrical and electronic
equipment (RoHS directive) apply in the European Community. In Germany, these pol-
icies are implemented through the "Electrical and Electronic Equipment Act" (ElektroG).
According to this, the following applies:
 Electric and electronic equipment are not to be included in household waste.
 Batteries and accumulators are not to be included in household waste but must

Safety instructions
14 PEM353_D00335_00_M_XXEN/06.2018
2.3 Intended use
The PEM353 is suitable for use in 2-, 3- and 4-wire systems and in their respective ver-
sions as TN, TT and IT systems.
The current measurement inputs of the PEM353 are always connected via external …/
1 A or …/5 A measuring current transformers. In principle, measurements in medium
and high-voltage systems are carried out via potential transformers.
Use for the intended purpose also includes:
 Device-specific settings compliant with local equipment and operating condi-
tions
 Adhering to the manual
Any other use than that described in this manual is regarded as improper.

3.2 Product description
The digital universal measuring device PEM353 is used to record and display measured
quantities of an electricity supply network, and make them available via the communi-
cation interface.
The range of measurements extends from voltages and currents to power and energy
meters to measured quantities of the voltage quality, such as THD and the individual
harmonics up to the 31st order.
The PEM353 is suitable for use in 2-, 3- and 4-wire systems and in their respective ver-
sions as TN, TT and IT systems. This allows monitoring single and polyphase systems.
With its standardised dimensions of 96 x 96 mm, the device is intended for front panel
mounting.

Bender Gateways provide advanced functions for the PEM353. In addition to visualisa-
tion, these also include convenient parameter setting and configuration via the web
browser. Parameter setting and configuration via gateway goes far beyond the setting
options on the display, as it includes many functions that would otherwise only be ac-
cessible via the communication interface.
For further information on Bender Gateways, please refer to our homepage.
Whether the PEM353 is supported by a Bender Gateway depends on the respective
firmware version. You can find a compatibility list on our homepage.
