4-1-5 Mounting methods

There are two methods for mounting the unit in the panel: screw mounting and rail mounting. Be careful to note that, as
compared with screw mounting, rail mounting is, on the one hand, advantageous in ease of mounting and removal, but on the
other hand has the disadvantage of being vulnerable to vibration or shock.

(1) Mounting with a DIN rail

You can use a DIN rail to mount a unit in locations not to subject to a vibration of 0.5G or more. As shown in the figure below,
use DIN EN50022 DIN rail.
7.5mm
Mounting a unit a Hold the unit facing its front, press it down with a 15 degree tilt onto the DIN RAIL. Swing it down until the
upper edge of DIN RAIL groove on the unit back touches the upper tab of DIN RAIL. Then use this locked-
in point as a pivot to press the unit forward on the bottom and lock it in position. The procedure is illustrated
below:
Make sure the tab is pressed in, or
it cannot be locked into position.
Dismounting a unit a Use a long screwdriver to reach in the hole on the DIN RAIL tab. Pull out the tab to "pulled out" position
to remove the unit, as shown in the figure below.
