Wiring (common instructions for 7903 series
and 7913 series)

1) Dismount the cover.

(i) Cable connection
Prepare the proper seal connector (order separately) in
advance, if required.
Screw the threaded seal connector into the main and
lead the cable through it.

(ii) Conduit connection
According to the number of cable cores, prepare a
conduit set (order separately) in advance.    Fix the
conduit connector and the attachment tentatively with a
screw.    Select an O-ring ideal for the cable.

Lead the cable, as shown in the following diagram.
Pull up the cable and fix the attachment to the main unit
with a screw.
Tighten the nut on the conduit at a point where the
conduit lock screw can be tightened easily.

2) Connect the wires to the terminals and close the cover.

Tighten the seal connector. (only when cable
connected)
