6 Electrical connection
The unit must be connected by a qualified electrician.
Observe the national and international regulations for the installation of electrical equipment.
Voltage supply according to SELV, PELV.
By means of basic insulation according to EN61010-1, the circuits are isolated from each other and
from device surfaces that could be touched (secondary circuit with max. 30 V DC, supplied from mains
circuit up to 300 V overvoltage category II).
CAUTION
Input current is not limited.
w
No fire protection.
u
Protect circuits.

≤ 120 s at max. 6.25 A (fire protection)
u
Alternatively supply the unit via a limited energy circuit according to IEC 61010-1 or class 2
according to UL1310.
Output reaction to overload or short circuit:
For self-protection of the output in case of excessive thermal load (due to short circuit or
overload), the output driver starts clocking. If a short circuit / overload continues for several
hours, the driver may be damaged!
u
Disconnect power.
