Correct Use
●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 hightemperature, high humidity andcorrosive gas may deteriorate itsperformance characteristic caused bycondensation or corrosive products,resulting in failure or burn damage ofthe Relay.
• PCB Terminal-equipped Relays weighapproximately 100 g.Be sure that the PCB is strong enoughto support them. We recommenddual-side through-hole PCBs toreduce solder cracking from heatstress.
• Relays with test buttons must bemounted facing down.Be careful not to touch the test buttonaccidentally. Doing so may turn ONthe contact.
• Be sure to use the test button for testpurposes only (with test-buttonmodels). The test button is used forRelay circuit tests, such as circuitcontinuity tests. Do not attempt toswitch the load with the test button.
●Micro Loads
• The G7L is used for switching powerloads, such as motor, transformer,solenoid, lamp, and heater loads. Donot use the G7L for switching microloads, 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.
●Connecting
• Refer to the following table whenconnecting a wire with a crimpstyleterminal to the G7L.
• Allow suitable slack on leads whenwiring, and do not apply excessiveforce to the terminals.
• Tightening torque
Coil : 0.78 to 1.18 N . m
Contact: 0.98 to 1.37 N . m
• 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.
Type | Receptacle terminals | Housing |
---|---|---|
#250 terminals (width: 6.35 mm) | XT3W-S441-12 XT3W-S442-12 XT3W-S443-12 | XT3B-1S white |
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.
