Check if the DIN-Rail mounting kit is installed firmly.
Step 1
Insert the bottom of DIN-Rail mounting kit (one side
Step 2
with spring support) into DIN-Rail, and then insert
the top into DIN-Rail.
Tips:
Insert a little to the bottom, lift upward and then insert
to the top.
Check and confirm the product is firmly installed on
Step 3
DIN-Rail, then mounting ends.

Disassembling DIN-Rail
】
Device
power
off.
Step 1
After lift the device upward slightly, first shift out the
Step 2
top of DIN-Rail mounting kit, and then shift out the
bottom of DIN-Rail, disassembling ends.
Notice before power on:
Power ON operation: First insert the power supply
terminal block into the device power supply interface,
and then plug the power supply plug contact and power
on.
Power OFF operation: First, remove the power plug,
and then remove the wiring section of terminal block.
Please pay attention to the above operation sequence.
【
Power Supply Connection
】
The product provides 3-pin 7.62mm pitch
terminal blocks, in which 1 and 3 are power
input and 2 is grounding. The power supply has the function of
non-polarity and anti-reverse connection, and the device can
still work normally after the reverse connection.
Voltage range: 12VDC~48VDC.
