Precautions
!WARNING
Take measures to prevent contact with charged parts when using
the Relay for high voltages.
■ Correct Use
Refer to the relevant catalog for common precautions.
1. Be sure to tighten all screws to the appropriate torque given
below. Loose screws may result in burning due to abnormal heat
generation during energization.
? M8 screws: 8.82 to 9.80 N·m
? M6 screws: 3.92 to 4.90 N·m
? M5 screws: 1.57 to 2.35 N·m
? M4 screws: 0.98 to 1.37 N·m
? M3.5 screws: 0.75 to 1.18 N·m
2. The G9EA and G9EC Relays’ contacts have polarity. Be sure to
perform connections with the correct polarity. If the contacts are
connected with the reverse polarity, the switching characteristics
specified in this document cannot be assured.
3. Do not drop or disassemble this Relay. Not only may the Relay fail
to meet the performance specifications, it may also result in dam-
age, electric shock, or burning.
4. Do not use these Relays in strong magnetic fields of 800 A/m or
higher (e.g., near transformers or magnets). The arc discharge
that occurs during switching may be bent by the magnetic field,
resulting in flashover or insulation faults.
5. This Relay is a device for switching high DC voltages. If it is used
for voltages exceeding the specified range, it may not be possible
to interrupt the load and burning may result. In order to prevent
fire spreading, use a configuration in which the current load can
13. The contact ratings are for resistive loads. The electrical endur-
ance with inductive loads is inferior to that of resistive loads. Con-
firm correct operation under the actual operating conditions.
14. Do not use the Relay in locations where water, solvents, chemi-
cals, or oil may come in contact with the case or terminals. Doing
so may result in deterioration of the case resin or abnormal heat-
ing due to corrosion or contamination of the terminals. Also, if
electrolyte adheres to the output terminals, electrolysis may occur
between the output terminals, resulting in corrosion of the termi-
nals or wiring disconnections.
15. Be sure to turn OFF the power and confirm that there is no resid-
ual voltage before replacing the Relay or performing wiring.
16. The distance between crimp terminals or other conductive parts
will be reduced and insulation properties will be lowered if wires
are laid in the same direction from the contact terminals. Use
insulating coverings, do not wire in the same direction, and take
other measures as required to maintain insulation properties.
17. Use either a varistor, or a diode plus Zener diode as a protective
circuit against reverse surge in the relay coil. Using a diode alone
will reduce the switching characteristics.
18. Do not tighten the screws to a torque exceeding 11 N·m for the
M8 screws and 5 N·m for the M5 screws.
Overtightening the contact terminals will reduce the switching per-
formance and damage the product.
19. Be sure to use the screws provided with the product for wiring coil
terminals and contact terminals. The specified tightening torque
cannot be achieved with different screws and may result in abnor-
mal heat generation when energized.
The coil’s power consumption can be reduced by using in combina-
tion with a semiconductor circuit. Consult your OMRON representa-
tive for details.
Recommended Wire Size
be interrupted in the event of emergencies.
In order to ensure safety of the system, replace the Relay on a
regular basis.
6. If the Relay is used for no-load switching, the contact resistance
may increase and so confirm correct operation under the actual
operating conditions.
7. These Relays contain pressurized gas. Even in applications with
low switching frequencies, the ambient temperature and heat
caused by arc discharge in the contacts may allow permeation of
the sealed gas, resulting in arc interruption failure.
In order to ensure safety of the system, replace Relays on a regu-
lar basis.
8. Do not use or store the Relay in a vacuum. Doing so will acceler-
ate deterioration of the sealing.
9. With this Relay, if the rated voltage (or current) is continuously
applied to the coil and contacts, and then turned OFF and imme-
diately ON again, the coil temperature, and consequently the coil
resistance, will be higher than usual. This means that the must-
operate voltage will also be higher than usual, exceeding the
rated value (“hot start”). In this case, take the appropriate counter-
measures, such as reducing the load current or restricting the
energizing time or ambient operating temperature.
10. The ripple percentage for DC relays can cause fluctuations in the
must-operate voltage or humming. For this reason, reduce the rip-
ple percentage in full-wave rectified power supply circuits by add-
ing a smoothing capacitor. Ensure that the ripple percentage is
less than 5%.
11. Ensure that a voltage exceeding the specified maximum voltage
is not continuously applied to the coil. Abnormal heating in the coil
may shorten the lifetime of the insulation coating.
12. Do not use the Relay at a switching voltage or current greater
than the specified maximum values. Doing so may result in arc
discharge interruption failure or burning due to abnormal heating
in the contacts.
