This is required to avoid motor burn-out in the event of a signifi-
cant increase in power absorption caused by a missing phase.

Electrical cable fastening
Use flexible cables according to EN 60 335-1. Regulations:
–
if in PVC sheath, use at least H05 VV-F;
–
if in rubber sheath, use at least H05 RR-F.
All cables to be connected to the burner terminal strip 6) (Fig. 7

The fairleads and precut holes can be used in various ways. One
example is given below:
The PRESS GW Model (Fig. 29)
1 - Single-phase power supply....................................... Pg 13.5
2 - Control devices TL .................................................... Pg 13.5
3 - Control devices TR ................................................... Pg 13.5
4 - Spare fairlead............................................................ Pg 13.5
5 - Fitting hole for fairlead, if required ............................... Pg 21
6 - Fitting hole for fairlead, if required ............................... Pg 11
7 - Fitting hole for fairlead, if required ............................... Pg 11
The PRESS 1G - 2G - 3G Models (Fig. 29)
1 - Three-phase power supply .......................................... Pg 21
2 - Single-phase power supply....................................... Pg 13.5
3 - Control devices TL .................................................... Pg 13.5
4 - Control devices TR ................................................... Pg 13.5
5 - Spare fairlead............................................................ Pg 13.5
6 - Fitting hole for fairlead, if required ............................... Pg 11
7 - Fitting hole for fairlead, if required ............................... Pg 11
8 - Fitting hole for fairlead, if required ............................... Pg 11
To ensure that the IP 40 protection classification is maintained,
close all unused fairlead fitting holes.
