Caution High Temperature Locate the panel section on which the CKR SSR will be mounted on. Overvoltage Protection Blank: Not Included P: Included 10 Using reasonable force, push CKR in the direction of the arrow shown in fig.1. 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.

For removal pull release tag in direction of arrow using blade of screwdriver and pull it away from DIN rail. Mounting clip incorporates tabs for screw mounting to panel Box Clamp terminals Bracket fits all standard 35 mm DIN rail profiles LED input status indicator Series Mounting on DIN Rail 20 Crydom CKR Series Solid State Relays were developed to offer the advantages of semiconductor switching technology in a standard 22.5 mm industrial package. Quick and easy installation is coupled with low drive power requirements and efficient, reliable power SCR output. This compact new design offers up to 30 Arms in ambient temperatures of 25ºC. Choose one of the two mounting options and follow the instructions below. 10 High Power Ready-to-Use DIN Rail Mounted SSRs Please read all installation instructions before using CKR Series SSRs. 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 (A) 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). Rev: 112613 Copyright © 2014 Custom Sensors & Technologies. Specifications subject to change without notice.
