or two wires can be connected.
Applicable Crimping Terminal
Be sure to use an insulation tube or cover on the crimping part of the crimping
terminal to prevent electrical shocks.
Solid Wire
Note: When connecting wires to contact blocks or transformers in the direction
shown below, keep the insulation stripping length 6.6 mm at the maximum.
Installing the Rubber Cover
When using the HW7D pushbuttons in places where the pushbuttons are
subjected to water splash or an excessive amount of dust, make sure to use the
HW9Z-D7D rubber boot (IP65) which is ordered separately.
Notes for Installing the Rubber Cover
Remove the gasket from the operator, and install the rubber boot on the operator.
Pull out the seals of the rubber boot and place them around the operator sleeve
as shown. Make sure that the seals are not twisted or tucked inside and that
the gasket does not remain, otherwise the normal waterproof and dustproof
characteristics are not ensured.
