Note
Observe the following for long-term storage:
For long-term storage, power must be applied to equipment with built-in capacitors for
five minutes at least every two years.
3.9.9 Product Protection
Table 28: Technical Data – Product Protection
Property Value
Internal input fuse
1)
T 6.3 A / 250 VAC
Transient suppression at input Yes, varistor
Overload protection at output Electronic
Overvoltage protection at output, max.
2)
60 VDC
Feedback voltage, max.
3)
Yes, max. 60 V
Degree of protection IP20
Ingress protection against foreign objects > 4 mm
Overtemperature protection
4)
Yes
Circuit breaker of the nominal current circuit
5)
16 A (for USA/Canada: 15 A)
1)
Used only as an AC fuse. An external DC fuse must be used with DC supply.
2)
Internal limitation via a second control loop, deactivation of power supply, automatic restart
3)
The voltage must not be exceeded due to power feedback.
4) Configurable; see section 8 “Latching Shutdown on Thermal Overload” Mode [ } 65]
5)
The circuit breaker can be used for activation during installation. In this case, the circuit breaker must meet
all the requirements on this shutdown device. If an additional switch is used, it must have the same electrical
load capacity as the circuit breaker.
