Installation Sheet DIN Rail Mount CTR Series MOUNTING INSTRUCTIONS DIN Rail Mountable SSRs Three-Phase Crydom CTR Series Solid State Relays were developed to offer the advantages of semiconductor switching technology in a compact, self contained package. Quick and easy installation is coupled with low drive power requirements and efficient, reliable power SCR output. FEATURES DIN rail or panel mount 90 mm (width) package Box Clamp terminals Bracket fits all standard 35 mm DIN rail profiles LED input status indicator Series CTR D 60 25 Operational Voltage 60: 48-600 VAC For options only and not required for valid part number Mounting on DIN Rail To install on DIN rail Locate rail and align with non moveable end of CTR DIN clip. Using reasonable force, push CTR in the direction of the arrow shown in fig.1. To remove from DIN rail fig.1 Mounting on DIN Rail Mounting on Panel Locate the panel section on which the CTR SSR will be mounted on. Operational Current 25: 25 Amps / Phase Required for valid part number Choose one of the two mounting options and follow the instructions below. For removal pull release tag in direction of arrow using blade of screwdriver and pull it away from DIN rail. PART NUMBER NOMENCLATURE Control Voltage B: 90-140 VAC C: 180-280 VAC D: 4-32 VDC Please read all installation instructions before using CTR Series SSRs. -10 Switching Mode Blank: Zero Voltage Turn-On -10: Random Turn-On (DC Control only) (A) The air gap is the clearance distance adjacent to either side of the relay or assembly measured to the next closer relay or assembly. (B) CTRCxxxx is rated at 60ºC max. ambient. (C) 100% Duty Cycle. 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 (A) To achieve maximum ratings if multiple units are installed, there must be a minimum air gap 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 CTR 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). Do not forget to visit us at: www.crydom.com Copyright © 2015 Custom Sensors & Technologies. Specifications subject to change without notice.
