## ● **Operating Environment Precautions** The rated value for the ambient operating temperature of the SSR is determined under conditions when there is no heat build-up. (Left graph) Note that it is necessary to reduce the load current as the ambient temperature of the SSR may increase due to operating conditions. (Figure below is an example of the G3M-205P(L) model) When using the SSR, design the system to allow heat dissipation sufficient to stay below the Load Current vs. Ambient Temperature characteristic curve. **==> picture [188 x 247] intentionally omitted <==** **----- Start of picture text -----**
