X42 terminal strip

Table 3- 5
Connector
Max. connectable cross-section: 2.5 mm
Note
Connection options for terminal strip X42
The terminal strip is not intended to be freely used for other 24 V DC loads (for example for
supplying additional line-side components), as the voltage supply of the Control Interface
Module could also be overloaded and operating capability could thus be compromised.

Fire due to overheating when the total length of the connecting cables is exceeded
Excessively long connection cables on terminal strip X46 can cause components to overheat
with the associated risk of fire and smoke.
• Limit the length of the connecting cables to a maximum of 10 m.
• Do not route the connection cable outside the control cabinet or control cabinet group.
