Tolerance: ±0.02 in / 0.5 mm All dimensions are in: inches [millimeters]

## **EQUIVALENT CIRCUIT BLOCK** 

**==> picture [372 x 69] intentionally omitted <==**

## **MOUNTING INSTRUCTIONS** 

Choose one of the two mounting options and follow the instructions. 

## **Mounting on Heat Sinks** 

- Select adequate heat sink. (Please refer to thermal derating curves for the specific model) 

- Be sure that thermal pad is pre-installed before installing over the heat sink. 

- EL mounting slots have a diameter of 0.16 in (4.0 mm). Two screws are needed (not included) 

- to mount the EL onto heat sink (See fig. 1). Recommended screw size is 8-32 (UNC standard) or M4 (metric). 

- Before applying full torque tighten down both screws until they contact the baseplate. Then, tighten them to 9.0-10.0 lb-in (1.0-1.13 Nm). 

- For optimal thermal performance heat sink fins should be oriented vertically to promote natural convection airflow. 

**==> picture [80 x 168] intentionally omitted <==**

## **Mounting on Panels** 

- Locate the panel section on which the EL 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 that thermal pad is pre-installed before install over the heatsink. 

- EL mounting slots have a diameter of 0.16 in (4.0 mm). Two screws are needed (not included) to mount the EL onto panel. Choose screw length considering the mounting surface hole depth and that the SSR flange thickness is 0.125 in (3.2 mm). 

- Before applying full torque tighten down both screws until they contact the baseplate. Then, tighten them to 10 lb-in (1.13 Nm). 

## **Transient Protection** 

Transients are common on AC power lines, and in extreme cases, may pose a risk for the proper operation and reliability of the SSR and its load. 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.

## **GENERAL NOTES** 

(1) For option P minimum power factor (at maximum load) is 0.9 

(2) In models with built-in overvoltage protection (“P” option), the output will self trigger between 450-600Vpk, not suitable for capacitive loads. 

- (3) All parameters at 25°C unless otherwise specified. 

- (4) When mounted to the proper size heat sink (see derating curves). 

- (5) Turn-on time for Instantaneous turn-on versions is 0.02 msec 

- (6) Elective Overvoltage Protection, “P” option.
