• The electrical connection may only be carried out by authorised personnel in a de-energised condi-
tion.
• As far as the electrical safety is concerned, the protection against unintentional contact of the con-
nected and therefore electrically interconnected apparatus and the insulation of the feed cables
must be designed for the highest voltage, which can occur in the device.
• To avoid EMC disturbances, the physical ambient and operational conditions at the place where the
product is installed, must meet the provisions laid down in the paragraph "Electromagnetic Compat-
ibility (EMC)" of DIN EN 60204-1.

6.2. Wiring example

• Single-channel control at terminal A1 of the SR4E4D01S expander module through a safety release of the
basic module
• The terminals X1 and X2 of the expander module must be connected to the feedback circuit or the single-
switch circuit of the basic module.
• Safety notice: The expander module must be wired in accordance with the wiring example. The
safety function is only realized in conjunction with the basic device.
