Basic Application Considerations of Bulletin 700-SF
High Density Mounting of Multiple SSRs
Connection
For DC load switching, the Bul. 700-SF SSR will operate properly if the load is connected to either the positive or negative load terminals.
Protective Component To Extend SSR Life
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.
For a DC inductive load, a diode should be connected parallel to the load to absorb the counter electromotive force (OFF) of the load.

Solid-State Relays
All units are in millimeters unless otherwise indicated. To convert to inches multiply by 0.0394. Dimensions are not intended for manufacturing
purposes.
If multiple SSRs are mounted side-by-side, be aware that the outer case wall of the SSR acts as a radiator. The SSR case serves to dissipate
heat. Install the relays so that they are adequately ventilated. If poor ventilation is unavoidable, reduce the load current by half.
Note: For additional details when using Solid-State Relays, refer to pub. 700-AT001*, Solid-State Relay Application Guide.
