Panel Mount Installation Sheet AC Output SSRs WIRING DIAGRAMS (B) Panel Mount Generic AC Output SSRs Wiring Diagram This installation sheet includes detailed mounting and wiring instructions which apply for most Crydom Panel Mount AC output SSRs. Be sure to visit the product series' datasheet available at the Crydom website to complement this information. If you have questions or need additional information please contact Crydom Tech Support. AC AC V Please read all mounting instructions before using your AC Output Panel Mount Solid State Relay (SSR). V 1 ( ) Load Load 2 ( ) 1 ( ) 2 ( ) MOUNTING INSTRUCTIONS (A) 1 Choose one of the two mounting options and follow the instructions. 2 OUTPUT S O L I D S TAT E R E L AY Mounting on Heat Sinks 4 Select adequate heat sink (see thermal derating curves in product series’ datasheet). Be sure to use a thermal pad or thermal compound (0.006 - 0.008 in layer thickness recommended) between the SSR and the selected heat sink. SSR mounting slots have a diameter of 0.2 in (5.0 mm). Two screws are needed to mount the SSR onto heat sink (See fig. 1). Mounting screws are sold separately as HK1 and are suitable for all Crydom heat sinks. Otherwise, recommended screw size is 8-32 (UNC standard) or M4 (metric) depending on the heat sink model, see product datasheet. Choose screw length considering the mounting surface hole depth and that SSR baseplate thickness is 0.125 in (3.2 mm). 3 INPUT 4 (– / ) 3 (+ / ) 1 2 OUTPUT S O L I D S TAT E R E L AY 4 3 INPUT 4 (– / ) 3 (+ / ) Terminals fig. 1 SSR mounted on HS053 heat sink (A) Before applying full torque tighten down both screws until they contact the baseplate. Then, tighten them to 20 in-lb (2.2 Nm). For optimal thermal performance heat sink fins should be oriented vertically to promote natural convection airflow. Screw, Quick connect or Installed standoff according to selection. Standard screw terminals are for Input: 6-32, Combo Drive; and for Output: 8-32, Combo Drive. Maximum screw torque is 15 in-lb (1.7 Nm) on input and 20 in-lbs (2.2 Nm) on output. Quick connect Single pair for models up to 25 Amp; Double pair for 50 Amp models only. User must connect both pairs. Installed Standoff model for PCB mounting or similar applications up to 50 Amp, standard screw torque is 8-10 in-lb (0.9-1.13 Nm) on Input and Output. (C) Wire Size Mounting on Panels Locate the panel section on which the SSR will be mounted. Panel mount surface must provide adequate heat sinking capability, uncoated, clean, flat (0.004 in/in recommended) and preferably aluminum. Be sure to use a thermal pad or thermal compound (0.006 - 0.008 in layer thickness recommended) between the SSR and the panel. Choose wire gauge according to actual load current (see TABLE 2). For larger wire sizes use lug terminals (see TABLE 1 for available part numbers). TABLE 2. Recommended Wire Sizes Terminals SSR mounting slots have a diameter of 0.2 in (5.0 mm). Two screws are needed (not included) to mount the SSR onto panel. Choose screw length considering the mounting surface hole depth and that the SSR baseplate thickness is 0.125 in (3.2 mm). Input Before applying full torque tighten down both screws until they contact the baseplate. Then, tighten them to 20 in-lb (2.2 Nm). Output TABLE 1.

The load which the SSR controls may also generate transients itself. Therefore, inclusion of transient protection for the SSR is highly recommended. Internal transient protection is standard in certain Crydom SSR models, and optionally available in others. The user may also install transient protection external to the SSR for additional protection. Contact Crydom technical support for additional information on use of transient protection for AC output SSRs. Important Considerations Be sure to use input and output voltages within operating ranges. LED indicates only input status. It does not represent output status. (A) See compatible accessories in corresponding datasheet. (B) Load can be wired to either terminal 1 or terminal 2. Proper polarity must be observed all the time for the DC control power supply, with terminal 3 being positive with respect to terminal 4. (C) Option “K” is designed and tested for use with printed circuit boards or ring/fork terminals having a thickness between 0.031 and 0.093 inches (0.79 to 2.36 mm), and loads rated up to 50 Amps. For higher load currents, the “K” standoff temperature must not exceed 105°C. For additional application assistance please contact Crydom Technical Support.
