Installation intervals
• The width of the load output terminal is 13 ㎜ and the width of input terminal is 7 ㎜ so
please use terminal that has less size than them and wire it strongly.
(Load Bolt M5, Control Terminal M3)
•Please make intervals more than the sizes in the following picture.
•Please install wiring duct less than half the height of the heat sink to prevent the flow of air.
•It is good to use Hanyoung Nux's HSR in lower than ambient temperature 25 ℃ so,
please use it lower than standard temperature.
•When using 40 A maximum load, please use 10 SQ wiring. Also please use clamping unit
or lugs when tightening wires.
How to install
•Please install HSR in the vertical direction.
•Otherwise, product's performance may be reduced to less than 50 %.
•When installing DIN rail, please install it stably since the product is heavy.

Information
POWER
Green
Light is on when applying 24 V d.c. to the detecting power terminal
INPUT
Green
When 4 - 32 V d.c. power is applied to control input terminal, the
brightness is getting higher in proportion to lighting voltage
AL 60°C
Red
Light is on when internal heat sink temperature is higher than 60 °C

Explanation for status display LED
Alarm output
• If heat sink temperature is lower than the set temperature, the alarm is automatically turned off.
• When internal heat sink temperature is more than 80 °C, operation will be forced to stop.
