3.5.1 Instructions for Using Splash-proof Connector Sets
The splash-proof connector sets for CN20 and CN21 assure the splash-proofness as
long as they are properly assembled and connected.
When using those connector sets, be sure to observe the following notes.
(1) The degree of protection of the splash-proof robot unit, which is
specified in Section 3.1 "Robot Specifications," is assured as long as the
splash-proof connectors are joined with connectors CN20 and CN21 on
the robot unit. If there is no connection on CN20 and CN21, the
splash-proof rating is not assured.
(2) Use a sheathed cable for a splash-proof connector. Using an unsheathed
cable cannot assure the splash-proof rating.
(3) Each connector set contains two types of cord clamps for CN20. Use the
one that matches the cable diameter.
(4) Each connector set should be assembled according to the instructions
specified by the connector manufacturer.
The table below shows an assembly procedure example of a connector set for CN21.
The actual assembly procedure should be in accordance with the instructions specified
by the connector manufacturer.

Assembly procedure example
(1) Treatment of wire ends: Strip the wire ends of the cable (prepared
by the customer). The cable diameter and the lengths "A" and "B"
should be in accordance with the instructions given by the
connector manufacturer.
(2) Tinning: Tin both the core wires and the connector contacts.
(3) Pass the cable through the heat-shrinkable tube for splash-proof
purpose (prepared by the customer) and the rubber bushing.
(4) Solder the core wires onto the connector contacts to connect
them each other.
(5) Press the rubber bushing against the shell to fit the hood. Then
cover the rubber bushing with the heat-shrinkable tube and apply
heat to shrink the tube.
