NOTES
1. When installing the relay, always
use washers to prevent loosening of
the screws.
Tighten each of the screws within the
rated ranges given below. Exceeding the
maximum torque may result in breakage.
Mounting is possible in either direction.
• M8 screw (150 A main terminal):
8 to 10 N·m
• M5 screw (150 A, 60 A main unit
mounting section): 2.5N·m to 3.6N·m
• M4 screw (60 A main terminal):
1.8 to 2.7 N·m
• M3.5 screw (Input terminal):
0.84 to 1.2 N·m
• M4 screw (10 A PC board type main
unit mounting section):
0.98N·m to 1.2N·m
(10 A TM type main unit mounting
section): 1.8N·m to 2.7N·m
2. The coils (150 A type) and the
contacts (10 A, 60 A, 150 A) of the relay
are polarized. Please follow instructions
in the connection schematic when
connecting the coils and contacts.
The 150 A type contains a reverse surge
voltage absorption circuit;
therefore a surge protector is not needed.
We recommend installing a surge
protector varistor (ZNR) for the 10 A and
the 60 A types. Avoid using a diode as
this may result in decreased cut-off
capability.
3. As a general rule, do not use a relay
if it has been dropped.
4. Avoid mounting the relay in strong
magnetic fields (near a transformer or
magnet) or close to an object that
radiates heat.
5. Electrical life
This relay is a high-voltage direct-current
switch. In its final breakdown mode, it
may lose the ability to provide the proper
cut-off. Therefore, do not exceed the
indicated switching capacity and life.
(Please treat the relay as a product with
limited life and replace it when
necessary.)
In the event that the relay loses cut-off
ability, there is a possibility that burning
may spread to surrounding parts, so
configure the layout so that the power is
turned off within one second.
6. Permeation life of internal gas
This relay uses a hermetically encased
contact (capsule contact) with gas inside.
The gas has a permeation life that is
affected by the temperature inside the
capsule contact (ambient temperature +
temperature rise due to flow of electrical
current). For this reason, make sure the
ambient operating temperature is
between –40 and 80°C –40 and +176°F,
and the ambient storage temperature is
between –40 and 85°C –40 and +185°F.
7. The case is designed to remain in
place during normal use and handling.
If the case is removed, the relay will not
function as intended and its performance
cannot be guaranteed.
8. If the power is turned off and then
immediately on after applying the
rated voltage (current) continuously to
the relay's coil and contact, the
resistance of the coil will increase due
to a rise in the coil temperature. This
causes the pick-up voltage to rise, and
possibly exceed the rated pick-up
voltage. In these circumstances, take
measures such as reducing the load
current, limiting the duration of
current flow, and applying a coil
voltage higher than the rated
operating voltage (quick start).
9. Coil operating power
Pure DC current should be applied to the
coil. The wave form should be
rectangular. If it includes ripple, the ripple
factor should be less than 5%. However,
check the actual circuit since the
characteristics may be slightly different.
The coil must only be supplied with its
rated voltage. The voltage waveform
supplied to the coil should be rectangular.
