Warning
Safety functions of EP-19xx modules can be impaired. When EP-19xx
modules are installed in the RSTi-EP station, observe the following points:
• Use wire-end ferrules in combination with flexible/multi-conductor

• Ensure that for safety inputs in the configuration without test pulses

6.4.1 Wiring of Modules with Standard Connectors

Wires with a cross section between 0.14 mm² and 1.5 mm² (AWG 26 – 16) can be connected.
The external dimensions of the crimped wire-end ferrules must conform with IEC‑60947-1.
RSTi-EP modules (except HD modules) and bus network adapters are equipped with the spring-style
connector system. Singlestrand and fine-strand lines with wire-end ferrules can be inserted without
the need for a tool.
•
Each cable must be the optimal length so the bending radii observe the manufacturer's
specifications.
•
Strip the insulation from the lines to a length of approx. 10 mm ± 1 mm (o.4 in ± 0.04 in), even
if you are using wire-end ferrules. If you use wire-end ferrules with plastic collars, strip the
wires to 12 mm ± 1 mm (o.5 in ± 0.04 in).
•
Connect all lines according to wiring diagram.
For the usage and handling of the spring-style system, refer to the section, Removing/Replacing
Cables.
