With 4-pole HG relays, use two HG2-Terminal sockets
for DIN rail assembly side by side.

TERMINAL SOCKET (SOCKET) COMBINATION
Because the pole numbers of the terminal sockets (sockets) are interchangeable,
different terminal sockets (sockets) can be used in combination.

NOTES
1. Hold-down clip
Please use the hold-down clip whenever
HG relays will be used in applications
where strong vibrating or shock force
occurs.
2. Mounting direction
There is no restriction on the mounting
direction. However, if the mounted relay
will be susceptible to strong vibrations or
shocks, to avoid influence on switching
operations, mount so that the direction of
vibration and shock are not in line with
the direction of contact switching. (In
direction of contact switching operation,
resistance to external shock is more than
98 m/s2). Moreover, if the mounted relay
is likely to be susceptible to strong
vibrations or shocks, be sure to fit the
hold-down clip.
3. Environment
Avoid use in adverse conditions, such as
where there is exposure to harmful gas,
or where ambient temperatures are high
(more than 40C).
4. Do not insert or remove relays into
or out of live circuits.
5. To prevent damage or distortion,
when tightening fixing screws, the
optimum torque range should be 1.176
to 1.37 N·m (12 to 14 kgf·cm).
For Cautions for Use, see Relay Technical Information.
