Danger!
Dangerous voltage
The leakage current to earth (PE) is > 3.5 mA AC or > 10 mA DC.
Possible consequences:
ƒ Death or severe injuries when the device is touched in the event of a fault.
Protective measures:
ƒ Implement the actions required in the EN 61800−5−1. Especially:
– Fixed installation
– PE connection must conform to standards (PE conductor diameter
³ 10 mm
2
or PE conductor must be connected twice)
Stop!
No device protection if the mains voltage is too high
The mains input is not internally fused.
Possible consequences:
ƒ Destruction of the device if the mains voltage is too high.
Protective measures:
ƒ Observe the maximally permissible mains voltage.
ƒ Fuse the device correctly on the supply side against mains fluctuations and
voltage peaks.
ƒ All power connections are plug connections and are coded. The connector set for the
ECSZE000X0B power supply modules must be ordered separately.
ƒ Installation of cables acc. to EN 60204−1.
ƒ The cables used must comply with the approvals required for the respective
application (e.g. VDE, UL, etc.).
