Position of modules and combination
NOTE:
(1) Only one A type module per meter in a maximum
combination of 3 total mixed modules on the same meter.
(2) Only one B type module per meter in a maximum
combination of 3 total mixed modules on the same meter.
(3) Only one C type module per meter in a maximum
combination of 3 total mixed modules on the same meter.
The B-C position is not mandatory,if to fulfil the application,
module “A” is not necessary, then maybe just “B” can be
mounted.
Another example: if modules “A” and “B” (anyone) arenot
needed, then just module “C” maybe be mounted. If “A”
module is needed, it is mandatory to put it in “A” position.
When no modules aremounted, then WM30-96 becomes a
simple indicator.
