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. |
