Precautions
Please refer to “PCB Relays Common Precautions” for correct use.
Dropping
Correct Use
Differences with the G2R
The G2RG-2A-X has the same terminal arrangement as the
G2R-2A4 but the switching capacity and electrical endurance are
different. Confirm that correct operation is possible in the actual
operating conditions before using in applications.
Handling
The enclosure rating of this product is flux protection. Therefore,
do not wash with water or detergent.
Mounting
The contacts of this product have polarity. Be sufficiently careful
because incorrect wiring may result in a failure to break the
circuit.
Install the product in a dry location with little dust and corrosive
gas.
Use in high temperature and humidity or an atmosphere
containing corrosive gas may lead to the relay itself failing or
suffering burn damage caused by performance deterioration due
to the influence of condensation or corrosive materials.
Do not use this product if it has been dropped.
Electrical endurance
Since this product is specifically for high DC voltages, the final
failure mode is failure to break the circuit, and in a worse-case
scenario, burning may extend to surrounding components.
Do not exceed the specified ratings or number of operations
during use, or use the product for any application other than high
DC voltages.
Implement a safety circuit and other safety measures to
minimize the risk in the event of a failure.
The electrical endurance of this product is the number of load
switching operations with a resistive load under the standard
testing conditions specified by OMRON.
The coil drive circuit, ambient environment, switching frequency,
or load condition (use under an inductive load or capacitor load)
may reduce the endurance and lead to a failure to break the
circuit. Always confirm operation with the actual equipment.
Connection of diodes to the operating coil
Connect a diode and zener diode to the relay coil (refer to the
following figure).
The diodes are for coil surge absorption. Switching performance
may be affected if only a diode is used, so use in combination
with a zener diode.
The coil has no polarity. Connect the diodes in the reverse
polarity of the voltage applied to the coil.
The recommended zener voltage of the zener diode is three
times the rated coil voltage.
