G9EJ-1-E DC Power Relays
Precautions
Take measures to prevent contact with charged parts
when using the Relay for high voltages.
Refer to the relevant catalog for common precautions.
1. The G9EJ 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.
2. Do not drop or disassemble this Relay. Not only may the
Relay fail to meet the performance specifications, it may also
result in damage, electric shock, or burning.
3. Do not use these Relays in strong magnetic fields of 800 A/m
or higher (e.g., near transformers or magnets). The arc dis-
charge that occurs during switching may be bent by the mag-
netic field, resulting in flashover or insulation faults.
4. 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 be interrupted in the event of emergen-
cies.
In order to ensure safety of the system, replace the Relay on
a regular basis.
5. If the Relay is used for no-load and/or minute load switching,
the contact resistance may increase and so confirm correct
operation under the actual operating conditions.
6. With this Relay, if the rated voltage (or current) is continu-
ously applied to the coil and contacts, and then turned OFF
and immediately ON again, the coil temperature, and conse-
quently 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 countermeasures, such as reducing the
load current or restricting the energizing time or ambient
operating temperature.
7. The ripple percentage for DC relays can cause fluctuations in
the must-operate voltage or humming. For this reason,
reduce the ripple percentage in full-wave rectified power sup-
ply circuits by adding a smoothing capacitor. Ensure that the
ripple percentage is less than 5%.
8. Ensure that a voltage exceeding the specified maximum volt-
age is not continuously applied to the coil. Abnormal heating
in the coil may shorten the lifetime of the insulation coating.
9. 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.
10.The contact ratings are for resistive loads. The electrical
endurance with inductive loads is inferior to that of resistive
loads. Confirm correct operation under the actual operating
conditions.
11.Do not use the Relay in locations where water, solvents,
chemicals, or oil may come in contact with the case or termi-
nals. Doing so may result in deterioration of the case resin or
abnormal heating due to corrosion or contamination of the
terminals. Also, if electrolyte adheres to the output terminals,
electrolysis may occur between the output terminals, result-
ing in corrosion of the terminals or wiring disconnections.
12.Be sure to turn OFF the power and confirm that there is no
residual voltage before replacing the Relay or performing wir-
ing.
13.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 termi-
nals. Use insulating coverings, do not wire in the same direc-
tion, and take other measures as required to maintain
insulation properties.
14.Use either a varistor, or a diode plus Zener diode as a protec-
tive circuit against reverse surge in the relay coil. Using a
diode alone will reduce the switching characteristics.
15.Use two M3 screws to mount a Relay with tab terminals. (The
tightening torque is 0.98 N·m.)
16.Manually mount Relays with PCB Terminals. Do not use auto-
matic soldering for them.
Do not bend the terminals to secure the Relay to the PCB.
17.A Relay with PCB Terminals weighs approximately 45 g.
Be sure that the PCB is strong enough to support it.
18.For the PCBs, we recommend dual-side through-hole PCBs
to reduce solder cracking from heat stress.
19.The coil terminals (A in the figure) and contact terminals (B in
the figure) on Relays with PCB terminals have charged metal
parts. Also, the shaded part in the following diagram may also
be charged. When you use the Relay, make sure that there is
no metal pattern on the corresponding part of the PCB.
