Do not short circuit the load (such as a relay coil). This

may damage the output relay.
Use surge absorbing devices appropriately in the relay
・
circuit (see the diagram above) to suppress surge
voltage from occurring. These devices are effective to
reduce noise-related problems and to extend the relay
life.
