7.2.1. Bus/Power connection
The EX245-FPS1/2/3 has two Power connectors (XD1/2) and two PROFINET communication connectors
(XF1/2). If only one connector is used, cover the unused connector with a blanking cap so that the
protection rating of IP65 is maintained.
Caution
"Blanking caps must be fitted to all unused bus & power connector ports to ensure an IP65 rating and to
prevent eye exposure to the light beam from the SCRJ connectors."
This rating must be maintained to guarantee PROFIsafe functionality.
For reasons of EMC a secure connection to the cable shield must be established on the PROFINET
(XF1/2) and Power (XD1/2).
Power and bus lines must be installed correctly.
To prevent manifold components of the EX245 from being damaged the supply lines for the electronics
and for the load voltage must be protected externally with a fuse.
All external supplies must meet the requirements of Section 2.2.2 of this manual.
Maximum loop through current between connectors must not be exceeded. Refer to EX245-FPS1/2/3
specifications table for details
The SI unit makes use of a CLASS 1 LASER product. Do not stare into beam visible at XF1 and XF2
