Electrical connection

5.2
When fitting the equipment in a metal or copper line, potential equalisation should be established as
shown in the following diagram.
Warning!
STOP
If functional earthing is connected up together with auxiliary power (left-hand plug) on the plug (point A),
then the line which is connected up to point B must have the same potential as point A. If this is not the
case, then connections may only be made to one point - either in plug (point A) or outside on equipment
(point B). We recommend connecting up functional earthing at point B. Refer to fig. 10.

Potential equalisation only with metal piping
Connection
Receptacle acc. to DIN 43650 with PG 9 screw connection,
line cross-section up to max. 1.5 mm2, type of protection IP 65
Open up plug and connect up as follows:
Left-hand plug = auxiliary energy
1 24 V AC/DC
2 GND

(Also refer to "Connection
peripherals" chapter)
Assembling plug
1. Use screw 1 to open the plug.
2. Take inner section 3 out of outer section 4.
3. Energise in accordance with connection arrangement.
4. The plug is assembled in reverse order.
