Connecting the heating elements and three-phase line
supply (PM4220 Highend: see figure 4/5,
POM4220 Flexible: see figure 6/7)
The heating elements are connected by means of two plug
connectors at X1 and X3 of the POM:
The 3-phase line is connected by means of one 3-pin plug
connector at X2 of the POM.
Note
The plug connectors for the heating elements and the power
connection are included in the scope of delivery of the
heating control system.
Features: Spring-type terminal and automatic tool-free
interlock or screwed joint (phase connection). To unlock,
press down the two levers on the sides of the plug
connectors.
To lock the plug connector in place correctly, press it in by
the plug body and not by the gray unlatching wedge.
NOTICE
The connected loads (heating elements) must not exceed
the maximum permissible current of 50 A per phase.
