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

and the ambient storage temperature is

between –40 and 85

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.
