 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.).
