Bus coupler in the BK housing (S20-PN-BK and S20-S3-BK)

NOTICE
The bus coupler can only be removed from the station after the bus coupler has
been slid to the left and thereby disconnected from the subsequent module.
NOTICE
Pushing the bus coupler on the DIN rail can result in damage to the FE contacts.
Check the contacts following removal of the bus coupler.
• Remove the left end bracket.
• Disconnect the bus coupler from the subsequent bus base module by sliding
it approximately 5 mm to the left (A). It must be completely removed from the
neighboring bus base module.
• Insert a suitable tool (e.g., bladed screwdriver) first in the upper and then in the
lower snap-on mechanism (base latches) of the bus coupler and release it (B).
The base latches are locked in place in the open position.
You can swap steps A and B. In this case, make sure to align the bus
coupler properly to avoid damage of the bus contacts.
• Remove the bus coupler perpendicular to the DIN rail (C). The base latches
return to the idle position again.
