(4) Consider the heat of PCB is necessary, please check the actual condition of PCB.
(5) Applying no diode to this relay. The life expectancy will be lower when a diode is used. To use

(6) Do not use the relay exceeding the coil rating, contact rating and life expectancy, or this may cause
(7) To assure optimum performance, avoid the relay from dropping, hitting, or other unnecessary shocks.
(8) Do not switch the contacts without any load as the contact resistance may become increased rapidly.
(9) Flux tight version is recommended. If there is cleaning process and sealed type is selected,
the vent-hole should be removed after the process.
