Mounting to the DIN Rail
Mounting
Catch the hook located on the top of the Unit onto the DIN Rail and
press the Unit until the Unit locks into place.
Dismounting
Pull down on the hook with a flat-blade screwdriver and lift up on the
Unit.
Mount one End Plate to each side of the EJ1C-EDU (PFP-M End
Plates are included with the End Unit).
Install the DIN Rail vertically to the ground.
Applicable DIN Rail (sold separately): PFP-100N (100 cm),
PFP-50N (50 cm)
Connecting to the G3ZA (EJ1N-TC)
Refer to the “G3ZA Instruction Manual” for wiring methods.
Connecting to the G3PW (EJ1N-TC)
Refer to the G3PW Instruction Manual for wiring methods.
(1) Lower the hooks.
(3) Press in
on the
Unit.
(2) Catch the upper hook
onto the DINRail.
