l to match.
ISOLATION PARTITIONS:
When operating with cross-connections, partition plates
have to be mounted between the cross-connection. This
is necessary in order to follow the prescribed air and
creepage distances.
SEPARATORS:
Some terminal types are used with separators when
operating them with cross-connections for to follow the
prescribed air and creepage distances. Separators can be
mounted subsequently between the cross-connections.
TEST-SOCKETS:
Sockets type STB are inserted in the busbar or screwed in
the modular terminal in place of the terminal screw. They
serve to take up the test sockets type PS.
TEST PLUGS:
Test plug type PS serve for the final testing of finished
wired terminal strips.
CROSS-CONNECTION SYSTEMS:
Q - Cross connection; QI - For cross connections the
cross connection bar, connection sleeve and fixing screw
are already captively mounted with the corresponding
number of poles.
