all instructions relating to safety.

1. Short instructions

2. Intended use

The digital universal measuring device PEM330/PEM333(-P) is

suitable for measuring and displaying electrical parameters of elec-

tricity networks. The device measures current, voltage, energy con-

sumption and power as well as the total harmonic distortion for

assessment of the voltage and current quality.

The accuracy of the active energy metering corresponds to class

0,5 S in compliance with the DIN EN 62053-22 (VDE 0418 Part 3-

22):2003-11.

•one sealing frame "IP54"

5. Installing the device

Front panel mounting (front view, side view, panel cut-out)

A front panel cutout of 92 mm x 92 mm is required for the device.

1. Fit the device through the cut-out in the front panel.

2. Put the 4 transparent mounting brackets from behind on the edges of the device.

3. Push the clips tightly against the panel to secure the device.

4. Check the device to ensure that it is firmly installed in the front panel.

Danger of electric shock!

Follow the basic safety rules when working with electricity.

Consider the data on the rated voltage and supply voltage as

specified in the technical data!

6. Connection of the device

Wiring diagram

Connection

1. The connecting terminals are located on the rear. Connect the

PEM330/PEM333(-P) to the supply voltage (terminals A1 and

A2 resp. +/-). Connect terminal " " to the protective con-

ductor.

2. Power protection by a 6 A fuse, quick response. If being sup-

plied from an IT system, both lines have to be protected by a

fuse.

3. Connection to the RS-485-Bus is made via the terminals D+,

D- and SH. Up to 32 devices can be connected to the bus. The

maximum cable length for the bus connection of all devices

is 1200 m.

8. Commissioning

Check proper connection

During installation and connection, abide by the relevant standards

and regulations and follow the operating manuals for the device.

Before switching on

1. Before switching on think carefully about these questions:

2. Does the connected supply voltage US correspond to the

nameplates information?

3. Is the nominal system voltage of the measuring current

transformer not exceeded?

4. Does the measuring current transformer's maximum current

correspond to the nameplate information of the connected

device?

Switching on

After switching on, proceed as follows:

1. Connect the supply voltage.

2. Set the bus address/IP address.

3. Set the CT transformer ratio (for each channel).

4. Change the measuring current transformer's counting direc-

tion, if required.

5. Set the nominal voltage.

6. Select wye connection or delta connection.
