C-B-11 Using DC-operated Relays
For a DC-operated Relay power supply, use a power supply with a
maximum ripple percentage of 5%. An increase in the ripple
percentage will cause humming.
C-B-12 Using DC-operated Relays
To make the correct connections, first check the individual terminal
numbers and applied power supply polarities provided in this catalog.
If the polarity is connected in reverse for the coil power supply when
Relays with surge suppressor diodes or Relays with operation
indicators are used, it can cause problems such as Relay
malfunctioning, damage to diodes, or failure of indicators. Also, for
Relays with diodes, it can cause damage to devices in the circuit due
to short-circuiting.
Polarized Relays that use a permanent magnet in a magnetic circuit
will not operate if the power supply to the coil is connected in reverse.
C-B-13 Using DC-operated Relays
If insufficient voltage is applied to the coil, either the Relay will not
operate or operation will be unstable. This will cause problems such
as a drop in the electrical durability of the contacts and contact
welding.
In particular, when a load with a large surge current, such as a large
motor, is used, the voltage applied to the coil may drop when a large
inrush current occurs to operate the load as the power is turned ON.
Also, if a Relay is operated while the voltage is insufficient, it will
cause the Relay to malfunction even at vibration and shock values
below the specifications specified in the specification sheets and this
catalog. Therefore, be sure to apply the rated voltage to the coil.
C Mounting Design
C-C-1 Lead Wire Diameters
Lead wire diameters are determined by the size of the load current.
As a standard, use lead wires at least the size of the cross-sectional
areas shown in the following table. If the lead wire is too thin, it may
cause burning due to abnormal heating of the wire.
C-C-2 When Sockets are Used
Check Relay and socket ratings, and use devices at the lower end of
the ratings. Relay and socket rated values may vary, and using
devices at the high end of the ratings can result in abnormal heating
and burning at connections.

C-C-3 Mounting Direction
Depending on the model, a particular mounting direction may be
specified. Check this catalog and then mount the device in the
correct direction.
C-C-4 When Devices Such as Microcomputers are in
If a device that is susceptible to external noise, such as a
microcomputer, is located nearby, take noise countermeasures into
consideration when designing the pattern and circuits. If Relays are
driven using a device such as a microcomputer, and a large current
is switched by Relay contacts, noise generated by arcing can cause
the microcomputer to malfunction.
D Operating and Storage

During operation, storage, and transport, avoid direct sunlight and
maintain room temperature, humidity, and pressure.

If Relays are stored or used for a long period of time in an
atmosphere of sulfuric gas or organic gas, contact surfaces may
become corroded and cause contact instability and obstruction, and
terminal soldering characteristics may be degraded.
Also, if Relays are stored or used for a long period of time in an
atmosphere of silicon gas, a silicon film will form on contact surfaces,
causing contact failure.
The effects of corrosive gas can be reduced by the processing

of the Relay. This condensation may cause insulation failure and
deterioration of insulation due to tracking (an electric phenomenon)
on the surface of the insulation material.
