A.9.2 Measures to comply with the UL-approbation
(UL 508C) for Size5, 6 and 6A
1. The devices must only be operated on networks of 1. overvoltage category III.
2. The devices can be used in networks with a maximum possible current of 10 kA
with phase symmetric current and a maximum voltage of 480 V with network
fusing acc. to table A.22.
3. The devices are designed for installation in 3. environments with pollution severity
2 acc. to EN 60664-1.
4. The integrated back-up fuse does not serve as protective device for branch
lines.The protective device for branch lines must be designed according to the
instructions of the manufacturer, the NEC regulations (National Electrical Code)
and other locally valid standards.
5. Only UL-approved circuit breakers and fuses of class RK1 may be used. For details
on the fuse rating see table A.22.
6. The device internal overload protection enables 2 times the rated device current
for minimum 3 seconds.
7. Only UL-qualified device connecting cables (mains, motor and control cables) must
be used:
− use copper cables with a temperature resistance of minimum +75 °C (+167 °F).
− Suitable tightening torques for terminals see table A.22
8. If the device is to be operated with an enclosed 8. external braking resistor, this
resistor must be separately protected against excessive temperatures.
9. Maximum ambient air temperature: see table A.16.
10. Technical boundary conditions for devices with 10. liquid-cooled see table A.20.
11. An isolated voltage supply with a nominal voltage of 24 V DC is to be used for the
relay output OSD04, the output from the supply is to be protected externally with
a 4 A fuse as per UL 248.
