Intended use
The PEM353 is suitable for use in 2-, 3- and 4-wire sys-
tems and in their respective versions as TN, TT and IT sys-
tems. The current measurement inputs of the PEM353 are
always connected via external …/1A or …/5A measuring
current transformers. In principle, measurements in medi-
um and high-voltage systems are carried out via voltage
transformers. Use for the intended purpose also includes:
• Device-specific settings compliant with local equip-
ment and operating conditions
• Adhering to the manual
Any other use than that described in this manual is regar-
ded as improper.

Mounting in a front panel
Mounting opening 92 mm x 92 mm (max. 92.8 x 92.8 mm).
1. Mount the rubber seal on the back of the device.
2. Insert the device into the mounting opening of the
front panel.
3. Place the four retaining clips over the device corners
from behind.
4. Push the retaining clips tightly against the front plate.
5. Check the device to ensure that it is firmly installed.
The device is installed.
Safety instructions
I 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 de-
struction of the device. Before installing and con-
necting the device, make sure that the installati-
on has been de-energised. Observe the rules for
working on electrical installations. Refer to the ra-
ted and supply voltage values as specified in the
technical data!

Current measurement inputs must not be "protected" by fuses. Provide a shorting block for each current measurement input as described in
IEC 60364-5-55 (edition 2.2) chapter 557.5.3 (wiring diagrams: disconnect terminal of the measuring current transformers "Y"). The current
measurement inputs must not be earthed in low-voltage applications.
