Narrow Mounting
When mounting the units closely in a horizontal row on 30mm centers, use op-
tional barriers to prevent interconnection between adjoining terminals. The barri-
ers can be attached simply by pressing them onto the sides of contact blocks.
Barrier

When mounting transformer type illuminated
units closely in a horizontal row on 30-mm
centers, insert solid wires or stranded wires
into inside of the terminal screw on the
transformer (see gure on the right) to prevent
short circuit between adjoining terminals.

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.
