Accessories

Make sure that the following things beside the main body part are included.

471B main unit

Bracket 2 pcs.

Waterproof packing

Quick Manual (This booklet)

(For the model with RS-232C or RS-485, exclusive quick manual is included.)

Mounting Method

Mounting pitch

Panel cutout dimensions: 92 0

＋0．8×45 0

＋0．6mm

Panel thickness: 0.6 to 3.5mm (Degree of protection IP65)

3.6 to 10mm (Degree of protection IP20)

If the material of the panel is aluminum, it may

be deformed due to its weak strength. So, it is recommended to use the

thickness of aluminum panel sheet at least 1.5mm.

Mounting Method to Panel

1Insert the main unit fitted with the waterproof packings into the hole, from the panel

front, and insert the attached bracket to the ditch on both sides of the main unit.

Push the bracket as shown by arrow ①until the main unit is stably stays and fix the

bracket. The packings functions as stopper too, so do not remove it. Refer to the

side view of the bracket mounting.

2To fix the main unit more firm, press the back part (center part) of the bracket

indicated by arrow ②by screwdriver, which enhances the stopper strength.

!Caution

When pushing by screwdriver, apply it to the arrow ②

The pushing of other part may cause the damage of bracket.

More than 30mm

More than 130mm

More than 75mm
