■Precautions

● Please refer to “PCB Relays Common Precautions” for general precautions.

● Installation

• Although there are not specific limits

on the installation site, it should be as

dry and dust-free as possible.

• Using in an atmosphere of high

temperature, high humidity and

corrosive gas may deteriorate its

performance characteristic caused by

condensation or corrosive products,

resulting in failure or burn damage of

the Relay.

• 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.

• Relays with test buttons must be

mounted facing down.

Be careful not to touch the test button

accidentally. Doing so may turn ON

the contact.

• Be sure to use the test button for test

purposes only (with test-button

models). The test button is used for

Relay circuit tests, such as circuit

continuity tests. Do not attempt to

switch the load with the test button.

● Micro Loads

• The G7L is used for switching power

loads, such as motor, transformer,

solenoid, lamp, and heater loads. Do

not use the G7L for switching micro

loads, such as signals.

● Soldering PCB Terminals

• Do not perform automatic soldering

but solder manually.

• Solder with the following conditions:

Soldering iron temperature (max.)

380°C, Soldering time within 10

seconds.

• Do not wash down the entire Relay

because it does not have an airtight

construction.

Correct Use

● Connecting

• Refer to the following table when

connecting a wire with a crimpstyle

terminal to the G7L.

• Allow suitable slack on leads when

wiring, and do not apply excessive

force to the terminals.

• Tightening torque

When connecting with screws, if the

screws are not sufficiently tightened,

the lead wire can become detached

and may lead to abnormal heating or

fire caused by faulty contact.

• Mounting Torque

0.98N . m

Tighten with two M4 screws when

mounting.

(Top bracket type)

• Do not apply excessive force when

mounting or dismounting the Faston

receptacle.Insert and remove

terminals carefully one at a time. Do

not insert terminals at an angle, or

insert/remove multiple terminals at the

same time.

• Do not connect to the terminals by

soldering

• Refer to the following table for

recommendations of connectors

made by OMRON.

Note. The current should be 25 A when using receptacle terminals.

● Reference Data

• The ratio of rated voltage between 100

to 120 VAC are values measured on

the basis of 100 VAC.

● Operating Coil

(Coil internal connections diagram)

• DC Coil

•AC Coil

• If a transistor drives the G7L check the

leakage current, and connect a

bleeder resistor if necessary.

• The AC coil is provided with a built-in

full-wave rectifier. If a triac, such as an

SSR, drives the G7L, the G7L may not

release. Be sure to perform a trial

operation with the G7L and the triac

before applying them to actual use.

● DIN Track Mounting Adapter and

Front-connecting Socket

(DIN Track Mounting)

• The DIN Track Mounting Adapter and

Front-connecting Socket can be

mounted on the G7L with just one

hand and dismounted with ease by

using a screwdriver.

• To support the G7L mounted on a DIN

Track Mounting Adapter or

Front-connecting Socket, use the

PFP-M End Plate. Put the End Plate

onto the DIN Track Mounting Adapter

or Front-connecting Socket so that the

surface mark of the End Plate faces

upwards. Then tighten the screw of

the End Plate securely with a

screwdriver.

(Screw Mounting)

• Screw-mount the DIN Track Mounting

Adapter or Front-connecting Socket

securely after opening screw mounting

holes on them.

• When cutting or opening holes on the

panel after the Front-connecting

Socket is mounted, take proper

measures so that the cutting chips will

not fall onto the Relay terminals. When

cutting or opening holes on the upper

part of the panel, mask the

Front-connecting Socket properly with

a cover.
