NOTES
1. Coil operating power
Pure DC current should be applied to the
coil. The wave form should be rectangular .
If it includes ripple, the ripple factor should
be less than 5%. However, check it with
the actual circuit since the characteristics
may be slightly different.
2. Coil connection
When connecting coils, ref er to the wiring
diagram to prevent mis-operation or
malfunction.
3. Soldering
We recommend the following soldering
conditions
Soldering: 200
°
C 392
°
F, max. 5 s
4. Others
1) If the relay has been dropped, the
appearance and characteristics should
always be checked before use.
2) The cycle lifetime is defined under the
standard test condition specified in the
JIS* C 5442-1996 standard (temperature
15 to 35
°
C 59 to 95
°
F, humidity 25 to
85%). Chec k this with the real device as it
is affected by coil driving circuit, load type,
activation frequency, activation
phase,ambient conditions and other
factors.
Also, be especially careful of loads such
as those listed below.
• When used for AC load-operating and
the operating phase is synchronous.
Rocking and fusing can easily occur due
to contact shifting.
• High-frequency load-operating
When high-frequency opening and
closing of the relay is performed with a
load that causes arcs at the contacts,
nitrogen and o xygen in the air is fused b y
the arc energy and HNO
3
is formed. This
can corrode metal materials.
Three countermeasures for these are
listed here.
• Incorporate an arc-extinguishing circuit.
• Lower the operating frequency
• Lower the ambient humidity
3) For secure operations, the voltage
applied to the coil should be nominal
voltage. In addition, please note that pick-
up and drop-out voltage will vary
according to the ambient temperature and
operation conditions.
4) Heat, smoke, and even a fire ma y occur
if the rela y is used in conditions outside of
the allowable ranges for the coil ratings,
contact ratings, operating cycle lifetime,
and other specifications. Therefore, do
not use the relay if these ratings are
exceeded. Also, make sure that the relay
is wired correctly.
5) Incorrect wiring may cause unexpected
events or the gener ation of heat or flames.
6) Check the ambient conditions when
storing or transporting the relays and
de vices containing the relays . F reezing or
condensation may occur in the relay,
causing functional damage. Avoid
subjecting the relays to heavy loads, or
strong vibration and shocks.
