●Alert Statements in This Instruction Sheet
Indicates a potentially hazardous situation which, if not avoided,
will result in minor or moderate injury, or may result in serious
injury or death. Additionally, there may be significant property
damage.
WARNING
When screw-fastening the body for use, vibration or the body’s own
weight may cause it to fall, and cause an injury if the screws are not
sufficiently tightened.
Mount the body using M5 screws tightened to a tightening torque of
1.2 to 1.6 N.m.
Do not open the cace and insert your hand inside the body before the
fan has stopped rotating. Doing so might cause an injury.
Before opening the cace to replace the filter, always turn the power
supply OFF, and make sure that the fan has stopped rotating.

PRECAUTIONS FOR SAFE USE
(1) AC adapter jack
For connecting the AC adapter (Always use the exclusive AC adapter.)
(2) Power supply/output terminals
Terminals for power input and alarm out put
For wire used for a terminal block,consider the following.
Wire length：30m and less
*1 Attached AC cord as standard is designed for use with 100 VAC (Japanese specications). When ZN-A4105 is
used in other than Japan, ZN-A4105D should be selected. AC adapter and AC cord is not supplied with it, please
connect DC power supply to terminal.

3 Baud rate selection
Baud rate : 38.4kbps Baud rate : 19.2kbps
(6) ID rotary switch
Used for ID settings when communicating with RS-422/RS-485. Need to set the IDs in
the following cases.
・ Connecting multiple ZN-As
・
Connecting with ZN-SF(Need to set IDs to ZN-As, even when connected with one ZN-A)
Give the different IDs to each ZN-As, and do not use "0" for ID number.
(Set an ID "0" only when the ZN-A is controlled by ZN-PDA. )
(7) DIP switch
Use this DIP switch when changing air volume changing method.
(4), (5)Terminal for communication (COMMUNICATION PORT)
Use for communicating by RS-422/RS-485, or for connecting Air Particle Sensor
ZN-PDA and Interface Unit ZN-SF(sold separately).
・When using Air Particle Sensor ZN-PDA or Interface Unit ZN-SF(sold separately), set
RS-422 communication and connect to the IN side.
Regarding communication setting, please refer to "(7)DIP SW".
・
During RS-422 communication, 24 VDC is supplied to (4)IN side communication terminal
(RJ-45) pin No.8. Do not connect Ethernet. The equipment might be damaged.
・When connecting multiple ZN-As during RS-422 communication, connect the (5) OUT
side to the next (4)IN side. (Don't connect the (4)IN side to each other.)
・Use straight type LAN cables for connecting between multiple ZN-As by RS-422 /
RS-485 communication.
・The cable length between devices must be 30m and less. The cables must be 100 m and
less in total length.
