Cautions for use
Please use our products in the conditions described in our specification sheets. Panasonic Corporation does not guarantee any failure caused by the usage in the
conditions beyond the specifications.
1.
Please visit our Automation Controls Products website and refer to the caution for use and the explanations of technical terms.
(https://www3.panasonic.biz/ac/e/control/relay/cautions_use/index.jsp)
2.
Please check the internal connection diagram in the catalog or specification, and connect the terminals correctly. If any wrong connection is made,
it may cause circuit damage by unexpected malfunction, abnormal heat, fire, and so on.
3.
When the voltage is applied to the relay coil exceeding ±5% range of the rated voltage, relay operation cannot be assured.
Additionally the ambient temperature and condition of the application should be considered under the worst condition of the actual usage because they may
change the relay operate and release voltage.
It is not allowed to apply the continuous maximum voltage to the coil. In order to obtain the specified performance, please apply the rated voltage.
4.
The coil voltage ripple factor should be max. 5%. When ripple current increases, the relay performance may be adversely affected, for example, the operation
sound may increase. The change of ambient temperature and condition affect the relay performance, please evaluate in the worst condition of the actual
usage.
5.
Lifetime is specified under the standard test conditions in JIS C 5442（1996）. (Temperature: 15 to 35℃， humidity 25 to 75%RH)
Lifetime is dependent on the coil driving circuit, load type, operation frequency, on/off phase and ambient conditions.
Check lifetime under the actual condition. The following load conditions may reduce lifetime:
a. If the on/off phase is synchronized with the AC load, contact lockup or welding may occur due to the material transfer of contact.
b. In the case of only inrush current with the DC load, contact lockup or welding may occur due to the material transfer of contact.
c. When switching loads that cause contact spark discharge at high frequencies, the resulting spark energy may synthesize HNO3 which causes contact
corrosion. To prevent this, take one or more of the following actions
i. Use a spark suppressor across the contacts.
ii. Reduce the operation frequency.
iii. Reduce the ambient humidity.
d. When“Dry-switching”without current conduction is used, please contact us.
Note: Dry-switching can reduce the consumption of contact material without current conduction. On the other hand, as the contact cleaning effect
disappears, conduction failure may occur. This dry-switching condition is not recommended in applying our relay.
6.
If the relay is dropped, it should not be used again.
7.
When a source of silicone gas (silicone rubber, silicone oil, silicone coating materials and silicone filling materials etc.) is used around the relay, the silicone
gas (low molecular weight siloxane etc.) may be produced. The produced silicone gas may penetrate the plastic case and enter the inside of the relay. When
the relay is kept and used in this condition, silicone compound may adhere to the relay contacts. The silicon compound may be changed to the insulator which
may cause the contact failure. Do not use any source of silicone gas around the relay.
8.
Do not use the relay in areas where flammable or explosive gases from gasoline and thinner, etc., may be present.
9.
Minimum switching load is a guide to the lower current limit of switching under the micro-load. This parameter is changed by the condition, such as switching
times, environment condition, and expected reliability. Therefore, Panasonic Corporation cannot assure the reliability. When the relay is used lower than
minimum switching load, reliability is attrition. Please use the relay over minimum switching load.
10. Please check the insulation distance between each terminal and ground.
11. Please evaluate the relay under the actual worst condition to enhance the reliability for the actual usage.
12. Please absolutely avoid the ultrasonic and high frequency vibration to the relay that adversely affects its performance.
13. In the case of using coil hold voltage under PWM (pulse width modulation) control, release voltages vary according to the temperature and usage condition.
Please evaluate the relay under the worst condition of the actual use. Recommended usage condition: Frequency: 20kHz to 100kHz, duty cycle: 50%
14. Please carryout the design which had an enough margin in conductor width and a space between conductors in the case of a design of a printed circuit board.
15. To detect the main contacts welding by Form b contacts, please design the appropriate detection time considering with the release and bounce time.
(4a1b type only)
16. Please avoid using or storing the relays from corrosive gas (sulfurous gas: SO2, hydrogen sulfide gas: H2S). Usage or storage under this kind of atmosphere
will contaminate contacts by ingredients of corrosive gas, which will result in contact failure.
