B : Insulation Check
After wiring is completed, check insulation of the
following terminals together with the wiring under the
condition of the converter side wiring terminals
disconnected.
Between terminal EX1 and terminal A, B, C
Between terminal C and terminal A, B
Between terminal A and terminal B
Between terminal EX1 and ground
Between terminal EX2 and ground
All insulation measurements must be performed with a
500V megger. Insulation resistances must be 100M
Ω
or more each.
IMPORTANT
Be sure to disconnect the cables at the terminal
of the converter when checking insulation.
C : Conduit Wiring
In case of conduit wiring, please use the waterproof
gland to prevent water flowing through the conduit
pipe into the wiring connection.
Please slope the conduit pipe down, and install a drain
valve at the low end of the vertical pipe.
Please open the drain valve regularly.
