IMPORTANT NOTES ON PANEL MOUNTING
OF SOLID-STATE RELAYS.
To avoid overheating and possible damage to the relay's circuitry, care must be
taken to provide adequate heat dissipation. NEVER OPERATE A SOLID-STATE
POWER RELAY IN FREE AIR OR WITHOUT A PROPER HEAT SINK.
Make sure that the mounting surface is clean, and free of paint or oxidation.
Apply a very thin layer of Heat Sink Compound onto the relay's metal mounting
plate. Take care to use proper torque when tightening the mounting screws.
Under normal operating conditions, the relay's case temperature should not
exceed 113°F (45°C). Additional heat sinking or a cooling fan must be provided if
the relay's operating temperature exceeds its optimum rating under load. Where
there is any question about the relay's ability to maintain a normal operating
temperature, a higher current relay should be specified.
