4.3 Power supply
Power is supplied to the HT 10 from a connection box through the connecting cable. The
following power consumption values for an HT 10 provide a conguration basis for calculating
the 24 V DC power supply supply.
Table 4-2 Input voltage specication
Typ. power consumption Max. power consumption
0.6 A 3 A (short-time)
Note
When using external power supplies (e.g. SITOP), the ground potential of the power supply must
be connected to the protective conductor connection of the system (SELV/PELV).
Note
Ground potential and enclosure (PE) are connected internally to one another with low
impedance.
Interface characteristics
The following special requirements apply to the connecting cables:
• The 24 V DC cable must be approved for temperatures up to 70 °C.
• Observe the permissible bending radius of the cables.
• Route all the cables so that they cannot be crushed or pinched.
• Route all the cables so that they cannot come into contact with chang edges.
Les câbles de raccordement doivent répondre aux conditions suivantes :
• Le câble 24 V CC doit être autorisé pour des températures jusqu'à 70 °C.
• Tenir compte du rayon de courbure admissible des câbles.
• Pose les câbles de manière à ce qu’ils ne pincent pas les câbles.
• Pose les câbles en évitant tout contact avec des arrêtes abrasives.
