Installing the TB 16IM-SC/TB 16SC Terminal Block
The terminal blocks are intended for installation in a cabinet or in an en-
closed casing or operating room.
The TB 16SC and TB 16IM-SC terminal blocks can be installed horizontally.
Provided temperatures do not exceed 40
_
C, other installation locations are
also possible.
When working out the space requirements of a terminal block, you must
maintain adequate clearances to other components.
These minimum clearances are necessary at installation and during operation
for the following reasons:
S
For installing and removing the terminal block and the electronic modules
S
To guarantee the air flow required for cooling during operation
S
TB 16IM-SC terminal block: You require a free space of 40 mm above
the terminal block and 50 mm under the terminal block (when using the
50 mm single-tier supplementary terminal or the 57 mm two-tier supple-
mentary terminal).
S
TB 16SC terminal block: You require a free space of 40 mm above the
terminal block and 20 mm under the terminal block (when using the
42 mm single-tier supplementary terminal or the 57 mm two tier supple-
mentary terminal).
If you carry out installation work with AC modules with a 230 V load supply
that involves disconnecting the protective conductor from the TB 16SC or
TB16 IM-SC, you must first switch off the 230 V load supply.
