Terminal Blocks
Safety Precautions
•
Remove power to the terminal blocks before starting
installation, removal, wiring, maintenance, and inspection
of the products. Failure to remove power may cause elec-
trical shocks.
•
For wiring, use wires of proper size to meet voltage and
current requirements. Tighten the terminal screws to the
recommended tightening torque. Failure to tighten the ter-
minal screws may cause overheating and fire. Also, the
screws may become loose due to vibrations. Tighten regu-
larly.
•
The recommended tightening torque is shown below:

•
For large capacity types, take into consideration the ten-
sion of the wires and tightening torque and make sure that
the crimping terminals are not twisted.
•
Grooves on the head of the hex bolt, for large capacity
types are for temporary tightening. For proper tightening,
use an applicable socket wrench and tighten within the
range of the recommended tightening torque.
•
Use an insulated crimping terminal.
•
Install a dust cover after wiring.

How to read the graph
When using IDEC terminal blocks, make sure that the operating temperature and the temperature of the bus bars do not exceed 100°C. How-
ever, the upper limit of the temperature rise is limited to 45°C by JIS C 2811.
Operating temperature + Temperature rise at bus bars
≤
100°C
Note: Select wires according to the allowable temperature, operating temperature, and temperature rise of bus bars.
