•
Make sure that the place of installation (switch cabinet etc.) has been disconnected
from the power supply.
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 cables.
•
Ensure that for safety inputs in the configuration without test pulses the cabling
prevents external short circuits (refer to DIN EN ISO 13849-2 Table D.4).
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. Single-strand 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 (0.4 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 (0.5 in ± 0.04 in).
•
Connect all lines according to wiring diagram.
For the usage and handling of the
spring-style
system, refer to Section, Removing/Replacing
6.4.2
Wiring of Modules with HD Connectors EP-8360
When using HD-connectors EP-8360 qualified wires with a cross section between 0.14 mm²
and 0.35 mm² (AWG 22
–
26) and an outer wire diameter between 1.0 und 1.6 mm (0.04 to
0.06 in) can be connected by insulation displacement connectors (IDC). A list of SAI cables
approved for the use with HD-connectors (Document-No. GFK-2971) is available to
download from the
https://www.emerson.com/Industrial-Automation-Controls/support.
Required tools:
•
Multi-stripax 6-16 (9202210000)
•
Pressing tool PWZ-UR20-HD (1525820000)
Note
:
When using HD-connectors EP-8360 two HD connectors must always be applied into
one slot of the connector frame.
