Basic Application Considerations For Bulletin 700-SC

Connection

For DC Load Switching, Bulletin 700-SC will operate properly if the load is connected to either the positive or negative SSR load terminal.

High-density Mounting of Multiple SSRs

If multiple relays are mounted side by side, be aware that the outer wall of each SSR works as a radiator.

The SSR casing serves to dissipate heat. Install the relays so that they are adequately ventilated. If poor ventilation is unavoidable, reduce the load current by half.

Protective Component

When controlling AC inductive loads, connect an inrush/surge absorbing device (varistor) across the SSR load terminals. If the SSR has built-in surge

suppression (Bulletins 700-SE and 700-SH) and additional surge suppression is required, connect the varistor across the terminals of the load device . Select

a varistor that meets the conditions of the load voltage outlined in the table below. Note: For additional details applying solid-state relays, refer to pub. number
