➍-4 Adhesion of Water, Chemicals, Solvent, and Oil

Do not use or store Relays in an atmosphere exposed to water,

chemicals, solvent, or oil. If Relays are exposed to water or

chemicals, it can cause rusting, corrosion, resin deterioration, and

burning due to tracking. Also, if they are exposed to solvents such as

thinner or gasoline, it can erase markings and cause components to

deteriorate.

If oil adheres to the transparent case (polycarbonate), it can cause the

case to cloud up or crack.

➍-5 Vibration and Shock

Do not allow Relays to be subjected to vibration or shock that exceeds

the rated values.

If abnormal vibration or shock is received, it will not only cause

malfunctioning but faulty operation due to deformation of components

in Relays, damage, etc. Mount Relays in locations and using methods

that will not let them be affected by devices (such as motors) that

generate vibration so that Relays are not subjected to abnormal

vibration.

➍-6 External Magnetic Fields

Do not use Relays in a location where an external magnetic field of

800 A/m or greater is present.

If they are used in a location with a strong magnetic field, it will cause

malfunctioning.

Also, strong magnetic field may cause the arc discharge between

contacts during switching to be bent or may cause tracking or

insulation failure.

➍-7 External Loads

Do not use or store Relays in such a way that they are subjected to

external loads. The original performance capabilities of the Relays

cannot be maintained if they are subjected to an external load.

➍-8 Adhesion of Magnetic Dust

Do not use Relays in an atmosphere containing a large amount of

magnetic dust. Relay performance cannot be maintained if magnetic

dust adheres to the case.

➎ Relay Mounting Operations

➀ Plug-in Relays

➎-➀-1 Panel-mounting Sockets

1. Socket Mounting Screws

2. Lead Wire Screw Connections

When mounting a panel-mounting socket to the mounting holes,

make sure that the screws are tightened securely.

If there is any looseness in the socket mounting screws, vibration

and shock can cause the socket, Relays, and lead wire to detach.

Panel-mounting sockets that can be snapped on to a 35-mm DIN

Track are also available.

Tighten lead wire screws to a torque of 0.78 to 0.98 N·m (P7SA and

P7S).

If the screws connecting a panel-mounting socket are not

sufficiently tightened, the lead wire can become detached and

abnormal heating or fire can be caused by the contact failure.

Conversely, excessive tightening can strip the threads.

➎-➀-2 Relay Removal Direction

Insert and remove Relays from the socket perpendicular to the socket

surface.

If they are inserted or removed at an angle, Relay terminals may be

bent and may not make proper contact with the socket.

➎-➀-3 Terminal Soldering

Solder General-purpose Relays manually following the precautions

described below.

1. Smooth the tip of the solder gun and then begin the soldering.

Note: For lead-free solder, perform

2. Use a non-corrosive rosin-based flux suitable for the Relay's

3. As shown in the above illustration, solder is available with a cut

When soldering Relay terminals, be careful not to allow materials

such as solder, flux, and solvent to adhere to areas outside of the

terminals.

If this occurs, solder, flux, or solvent can penetrate inside of the

Relays and cause degrading of the insulation and contact failure.

➁ Printed Circuit Board Relays

➎-➁-1 Ultrasonic Cleaning

Do not use ultrasonic cleaning for Relays that are not designed for it.

Resonance from the ultrasonic waves used in ultrasonic cleaning can

cause damage to a Relay's internal components, including sticking of

contacts and disconnection of coils.

➂ Common Items

➎-➂-1 Removing the Case and Cutting Terminals

Absolutely do not remove the case and cut terminals. Doing so will

cause the Relay's original performance capabilities to be lost.

➎-➂-2 Deformed Terminals

Do not attempt to repair and use a terminal that has been deformed.

Doing so will cause excessive force to be applied to the Relay, and

the Relay's original performance capabilities will be lost.

➎-➂-3 Replacing Relays and Performing Wiring

Before replacing a Relay or performing a wiring operation, first turn

OFF the power to the coil and the load and check to make sure that

the operation will be safe.

➎-➂-4 Coating and Packing

G7S, G7SA and G7SB Relays are not fully sealed, so do not use a

coating or packing resin.

Solder: JIS Z3282, H60A or H63A (containing rosin-based flux)

Soldering iron: Rated at 30 to 60 W

Tip temperature: 280 to 300°C

Soldering time: Approx. 3 s max.

For flux solvent, use an alcohol-based solvent, which tends to be

less chemically reactive.
