!

Caution

When handling and installing the CP 243-2, make sure that you keep to the ESD guidelines.

The CP 243-2 must only be connected when the AS-i power supply unit is turned off.

Caution

Noise immunity/grounding

To ensure the noise immunity of the CP 243-2, the CP 243-2 and the AS-i power supply unit must be correctly grounded.

Caution

The AS-i power supply unit used must provide a low voltage, safely isolated from the network. This safe isolation can be implemented according to the following requirements:

SVDE 0100 Part 410 = HD 384-4-4 = IEC 364-4-41 (as functional extra-low voltage with safe isolation) or

SVDE 0805 = EN60950 = IEC 950 (as safety extra-low voltage SELV) or

SVDE 0106 Part 101
