K108_en Rev 1 7 Application Notes 1. It is possible that during transit or final assembly the relay could change state. Therefore, it is recommended that all relays be set to the desired state via a power supply. 2. Do not energize both coils of dual coil relays simultaneously. 3. Applying excessive heat to the relay terminals can cause damage to the internal structure of the relay and should be avoided. 4. Moving or bending the terminals can cause damage to the internal structure of the relay and should be avoided. 5.
