Precautions
I
HANDLING
To preserve initial performance, do not drop or otherwise
subject the power relay to shock.
The case is not designed to be removed during normal
handling and operation. Doing so may affect performance.
Use the power relay in a dry environment free from
excessive dust, SO
2
, H
2
S, or organic gas.
Do not allow a voltage greater than the maximum allowable
coil voltage to be applied continuously.
Do not use the power relay outside of specified voltages and
currents.
Do not allow the ambient operating temperature to exceed
the specified limit.
I
INSTALLATION
Although there are not specific limits on the installation site,
it should be as dry and dust-free as possible.
PCB terminal-equipped relays weigh approximately 100 g.
Be sure that the PCB is strong enough to support them. We
recommend dual-side through-hole PCBs to reduce solder
cracking from heat stress.
Quick-connect terminals can be connected to fast on
receptacle #250 and positive-lock connectors.
Allow suitable slack on leads when wiring, and do not
subject the terminals to excessive force.
I
CLEANING PCB TERMINALS
PCB terminals have semi-sealed construction which
prevents flux from entering the relay base. It is
recommended that the user should apply a tape seal over
the vent hole prior to wave soldering or cleaning. The tape
should then be removed after processing.
I
OPERATING COIL
As a rule, either a battery or a DC power supply with a
maximum 5% ripple is used for the operating voltage for DC
relays. Before using a rectified AC supply, confirm that the
ripple is not greater than 5%. Ripple greater than this can
lead to variations in the operating and reset voltages.
As excessive ripple can generate beats, the insertion of a
smoothing capacitor is recommended as shown below.
When driving a transistor, check the leakage current and
connect a bleeder resistor if necessary.
Momentary voltage drops on coil input voltage should not
exceed one second duration after contact mating with no
shock or vibration.
