Brief description

The conﬁ gurable SINEAX CAM measuring unit is designed for AC power

distribution systems or industrial facilities. The reliable device determines

the current network condition and the degree of impurity caused by non-

linear consumers through a comprehensive harmonics analysis.

The device is also suited to the acquisition of special input signals with

variable sampling intervals (e.g. full wave controls), altered sine shapes

(e.g. phase-angle controls) or strong distortions.

Mounting

The device is mounted on a top-hat rail.

Please ensure that the operating temperature limits are

not exceeded when determining the place of mounting

(place of measurement):

– 10 … 55 °C

Snap housing on the top-hat rail (EN 50 022) (see Figure 1).

Figure 1. Mounting on top-hat rail 35 x 15 or 35 x 7.5 mm.

Disassembly

Remove the housing from the mounting rail according to Figure 2.

Electric connections

Screw connections are used. They are designed for cross sections of

4 mm

2

for single wire leads and 2 x 2.5 mm

2

for multiwire leads.

Ensure under all circumstances that the leads are free

of potential when connecting them!

Please observe, …

… that the data on the type plate must be adhered to!

A marked and easily accessible switch for turning off the power

supply has to be arranged in the vicinity of the device.

In case of a supply of direct current > 125 V DC, an external fuse

has to be provided in the power supply circuit.

Otherwise, the national provisions (e.g. in Germany VDE 0100 “Con-

ditions concerning the erection of heavy current facilities with rated

voltages below 1000 V”) have to be observed in the installation and

material selection of electric lines!
