Grounding Installation
Ø The outer case for the module is made of iron and fitted with a fan
and convection holes with filters.
Ø If possible, wiring should be connected to the module through an
external terminal block (T/B) to avoid external wires directly getting
into the inside of the module. Its advantages are (1) a clear demar-
cation for external/internal wiring responsibility, (2) wire numbering
can be arranged in an explicit and concise manner, and (3) an easy
diagnostics for the wiring problems and a more aesthetical layout
plan.
