Picking power line and transmission line
•
Pick the power line from the upper hole on the left side plate, from the front position of the main unit (Through the conduit hole of the wiring
mounting plate - optional parts) or from a knock out hole to be made in the unit’s bottom plate.
Precautions when knocking out knock holes
•
Be sure to avoid damaging the casing
•
After knocking out the holes, we recommend you paint the edges and areas around the edges using the repair paint to prevent rusting.
•
When passing electrical wiring through the knock holes, wrap the wiring with protective tape to prevent damage.
•
Open knock holes around the 4 concave knock holes in the base frame, using a
φ
6mm-bit drill.
•
If you pick the power line from the front position of the unit, proceed as follows and refer to figure
– Remove the lower frontplate (1), punch a hole in the knock hole and cut the hole (2) all the way to the slit.
– Attach the 3 sealing pads (Optional parts) (3) on the wiring mounting plate (Optional parts) (4) corresponding
to the overlapped area of the front plate.
– Install the wiring mounting plate to the front side of the side plate with the 2 delivered screws.
•
Pick the transmission line from the middle positioned conduit hole on the left side plate, from the lower conduit
hole on the right side plate or from the front position of the main unit (After binding it to the piping with
finishing tape as in figure 2).
