| Selecting proper Accessories
and using them correctly during assembly of Terminal Blocks is a very
important function on the part of assembly-designers and assemblers
of terminals blocks.
These accessories are specially designed by
elmex to perform one or more of the following functions, which ulimately
help the user to derive optimum benefit from use of elmex terminals.
» END PLATE : for insulating end-of-stack terminals
and for assembly of terminals of different sizes. »
BARRIER PLATE : for increased values of clearances and
creepages if required in specific applications / (standard designs
already provide more than necessary values as per IEC60947-7-1.)
and also for visible segregation of groups of terminals.
» END CLAMP : for holding the stack of terminals
blocks together, along the length of mounting rails.
» SHORTING LINK : for inter connecting the
terminals, use of factory-made terminal-shorting-links, rather than
using inefficient and unreliable wire looping or adding extra terminals,
for the purpose of inter connections.
» PROTECTIVE COVER : for making entire stack
of terminal block 'finger safe' , as preferred in some applications.
» GROUP MARKER : for identification of individual
terminals and for group-identification.
Naturally, use of accessories is first to be conceived by the assembly-designer
of terminal blocks. Certain accessories such as End plates and End
Clamps are mandatory. It is therefore as important to select proper
accessories as to select terminal blocks, so that installation,
maintenance and fault-tracing are all simplified at the design stage
itself.
Necessary guidance for selection of accessories available for all
the types of terminals blocks, is given in following pages. The
data on accessories for individual Terminals is provided with each
terminal in the previous pages. |
