2. Wiring
Lay the product cable away from any high-voltage cable or power line.
If laid in the same conduit or duct, induction noise from them may caused malfunction or breakdown of
the product.
Be sure to turn the power OFF before inserting or removing the I/O terminals. Otherwise it may result in
a failure.
Do not connect ZN-DPX21-S to a sensor head other than ZN-DPS1-S. Do not conect
ZN-THX21-S and ZN-THX11-S to a sensor head other than ZN-THS1-S. Do not hold only the
sensor head mounted to the product body.
3. Battery Use
Do not combine use of new and old batteries, or do not use batteries in combinations with those of
different makers or models. Doing so may result in malfunction.
Do not insert a battery with the polarity inverted.
Be sure to mount a battery cover during use. Be careful that the operation of the device cannot be
guaranteed if a battery is removed because the battery cover is not mounted.
Remove the batteries if you do not use the product for a long period of time. If leaving the used batteries
in the product for a long period of time, corrosion of the device may occur due to a battery leak.
Do not disassemble or throw the battery into the fire.
When the battery level is low, a restart may be repeated. If such event occurs, replace the batteries with
new ones.
When using network connection mode, use an AC adapter because the battery becomes exhausted fast.
