MOUNTING INSTRUCTIONS
Please read all installation instructions before using CKR Series SSRs.
Choose one of the two mounting options and follow the instructions below.
Mounting on DIN Rail
Locate rail and align with non moveable end of CKR DIN clip.
Using reasonable force, push CKR in the direction of the arrow
shown in fig.1.
For removal pull release tag in direction of arrow using blade of
screwdriver and pull it away from DIN rail.
Mounting on Panel
Locate the panel section on which the CKR SSR will be mounted on.
DIN clip includes tabs for this type of mounting. Tab holes have a
diameter of 4.5 mm. You will need two screws (not included) no
larger than that to mount the SSR onto panel.
Align SSR tabs with panel surface and screw both top and bottom
sides. Recommended torque is 12 in-lbs (1.36 Nm).
IMPORTANT CONSIDERATIONS
Mounting Air Gap
To achieve maximum ratings, there must be a minimum spacing of 0.8 in (20 mm) between
the devices (horizontally) and of 3.15 in (80 mm) measured between DIN clip tabs (vertically).
Earth Bonding (Grounding)
The CKR heat sink is equiped with an earth bonding screw as is required for Class 1
Protection, in accordance with EN 60950 (VDE 0804). Recommended torque is 20 in-lbs
(2.2 Nm).
