Power Supply from the AS−Interface
!
Caution
The AS-i power supply unit used and the optional external power supply must
provide an extra low voltage safely isolated from the mains supply. This safe
isolation can be implemented according to the following requirements:
S
VDE 0100 Part 410 = HD 384-4-4 = IEC 364-4-41
(as functional extra-low voltage with safe isolation) or
S
VDE 0805 = EN60950 = IEC 950
(as safety extra-low voltage SELV) or
S
VDE 0106 Part 101
The IE/AS-i LINK can be supplied fully from the AS-Interface (only AS-i line 1). The
current consumption from the AS-Interface is 320 mA at 30 V.
As an alternative, the IE/AS-i LINK can be supplied by a separate power supply
unit (24 V DC).
Power Supply from external Power Supply
!
Warning
The device is designed for operation with safety extra
−
low voltage (SELV). This
means that only safety extra
−
low voltages (SELV) complying with
IEC950/EN60950/ VDE0805 may be connected to the power supply terminals.
The power unit for supplying the device must comply with NEC Class 2 as descri-
bed by the National Electrical Code(r) (ANSI/NFPA 70).
The power of all connected power units in total must correspond to a limited power
source (LPS).
Never operate the IE/AS-INTERFACE LINK PN IO with AC current or DC current
higher than 32 V.
With a double master, you require a separate power unit each for AS
−
i line 1 + 2.
If the cable to the external power unit is very long and liable to energy spikes,
connect a surge protection element.
