Performing electrical installation
Important
To ensure secure fastening of the connected connectors and adherence to the enclosure
rating, the knurled nuts/coupling rings of the M12 connectors have to be tightened or the
cable connectors have to be secured.
1. Connect or release current linkages only under de-energised conditions.
2. All wire cross sections and their shields on customer side have to be selected and im-
plemented according to valid engineering standards.

Connecting the power supply for the interrogator
For the operation, the interrogator requires a supply voltage of 10 ... 30 V DC (functional ex-
tra-low voltage in accordance with IEC 60364-4-41 (VDE 0100 (part 410)). The functional
extra-low voltage can be created using a safety transformer in accordance with IEC 742
(VDE 0551). The maximum current consumption is 5 W.
Via the connection module CDB620 or CDM420, the interrogator is supplied with
10 ... 30 V DC. If the power supply module CMP400/CMP490 is used, the input voltage is
100 ... 250 V AC/50 ... 60 Hz on the module.
Important
The output circuit of the power supply unit must be electrically separated from the input
circuit. This is usually created by means of a safety transformer in accordance with
IEC 742 (VDE 0551).
Damage to the connector unit on the interrogator due to overwinding.
The connector unit on the interrogator has two end positions.
>
Never turn the connector unit, of one of the two end positions, more than 180° in one
direction.
>
Always rotate the connector unit in the direction of the type plate.
