The diagram below shows the front of the bracket (the side into which the
panel-mounting bolt is inserted). Rotating the bracket 90 makes the bracket
compatible with either ANSI or JIS panel cutouts. Set the bracket to either
the ANSI or JIS mark according to which type of panel you are installing, as
shown in the diagram.

Attaching the Dust Cover and Terminal Cover
WARNING
As there is a danger of electric shock, do not attach the dust
cover and terminal cover while the wires are live.
• Attach the dust cover before attaching the terminal cover.
• The recommended tightening torque for the screws for attaching the
dust cover and terminal cover is 0.4N•m.
3.1 Attaching the Dust Cover
Dust cover
(standard accessory)
Insert into
the
marked
grooves
Insert the two protruding
portions on the underside of the
dust cover into the grooves on
the upper side of the PR300 as
shown in the diagram below.
1
Secure the dust cover with the screw
provided as shown in the diagram below.
2
(recommended tightening torque: 0.4 N•m)
3.2 Attaching the Terminal Cover
Complete the wiring to the terminals
2, 4, 6, 8, 23, 24, and 25, then
secure the terminal cover in the
open state shown in the diagram
below with the two screws provided.
1
Complete the wiring to other
terminals with the terminal
cover open shown in the
diagram below.
2
Close the terminal cover and secure it
with the screw provided as shown in
the diagram below.
