１. CHECKING THE PRODUCT
１－１. MODEL CODES
Please check that the product has been delivered matches the
model code ordered in reference to "19. SPECIFICATIONS".
２. PRECAUTIONS FOR USE
２－１. ENVIRONMENTS AND CONDITIONS OF USE
Please do not use the product under the following circumstances.
It might cause malfunctions and shortening the life of the
product.
1） Ambient temperature of out of -5 to
2） Ambient humidity of out of 35 to 85%, or freezing
condensing
3） Excessive dust or metal particles
(Storing in a dust-proof chassis and a countermeasure
against heat dissipation are required.)
4） Environment of corrosive gas, salty air or oily smoke
5） Environment of much vibration or impact
6） Environment of rain or water drops (except the front
panel)
7） Environment of strong electromagnetic field or much
exogenous noises.
２－２. INSTALLATION AND CONNECTION
1） Please read this manual before the installation and the
connection of wires. And they should be performed by a
person having a specialized technique. In addition, the
insulation class of the WPMZ is as shown by the figure
below. Please confirm that the insulation class satisfies a
use condition prior to the installation.

2） Do not wire the power supply line, input signal lines and
output signal lines near noise sources or relay drive lines.
3） Bundling or containing in a same duct with lines including
noises might cause malfunctions.
4） The WPMZ becomes available functionally right after
power activation, but requires 30 minutes' warming to
satisfy all performance requirements.
Note: The inputs "A channel" and "B channel" may be
abbreviated to "Ach" and "Bch" in this manual.
２－３. CHECKING BEFORE USE
Install the WPMZ under the environments and conditions of use
which meet requirements.
If you find any damage to the product or any problem, please
contact to your dealer or our company directly.
