1. Safety Precautions
WARNING Incorrect handling could cause serious injury or death.
- Use a dedicated circuit for the equipment to be connected, and use the voltage and breaker appropriate for the connected load.
- Connected equipment should be used within the rated voltage and control capacity range.
- Never modify or repair by yourself.
If the product is modied or inappropriately repaired, electric shock, re, etc. could result. Contact your dealer for repair.
- Do not move or reinstall the product by yourself.
If it is installed improperly, electric shock, re, etc. could result. Contact your dealer or technical representative.

Terminal block of this product.
Improper connection could result in heat generation or re.
- All electrical work must be performed by a licensed technician, according to local regulations and the instructions given in this Installation
manual.
- Ensure that installation work is done correctly following this Installation manual.
If it is installed improperly, electric shock, re, etc. could result.
- Close the control cover after installation.
-Donotinstalltheproductinaplacewhereammablegasesmayleak.
If gas should leak or accumulate around the product, re or explosion could result.
- Do not use the product in special environments.
The product could be damaged if it is used in locations subject to large quantities of oil (including machine oil), steam, or sulde gas.
-Donotinstalltheunitinaplacewherethetemperaturerisesabove40˚C(104°F),wherelargeamountsofoil,steam,organicsolvents,or
corrosive gases, such as sulfuric gas, are present, or where acidic/alkaline solutions or sprays are used frequently.
These substances can compromise the performance of the unit or cause certain components of the unit to corrode, which can result in electric
shock, malfunctions, smoke, or re.
CAUTION Incorrect handling could cause injury or damage to property or household e󰀨ects.
- Wire so that it does not receive any tension.
Tension could cause wire breakage, heating or re.
- Put on gloves during installation.
Failure to do so could cause injury.
■ This manual must be read both fully and carefully before commencing installation procedures; furthermore, the subsequent installation must be
performed correctly and safely in accordance with the instructions given.

Be sure to perform installation while the power of the Lossnay
unit is OFF.
* Depending on the model of Lossnay or
installation condition, the actual PCB and
following diagram can be upside down.
3.1RemovingtheControlBoxCoverofthe
Lossnay Unit
For more information, please refer to the installation and
operation manual of the Lossnay.
* Figures show the installation method of LGH-RVS series.
Remove the three black screws and remove the control box cover
of the Lossnay unit.
3.2 Installing PZ-4GS-E
Use the included installation screws (2) to install PZ-4GS-E to the
PZ-4GS-E installation position on the side of the circuit board.
Note
●Be sure to use the included installation screws.
● Tighten the screws with a torque of 1.42 ± 0.25 N・m.
● During installation, be careful not to damage the Lossnay unit
control board by tools or other objects.
●Connecttheleadwirestotheterminalblocks(TM2,TM3,TM4,
TB5)beforeinstallingthePZ-4GS-E.

3.3 Connecting the Cable
Connect the connector (CN500) on the PZ-4GS-E to the connector (CN50)
on the Lossnay unit control board using the included connection cable.
Note
● Insert the cable all the way until a locking sound is heard.
● Be sure not to apply force to the connector.
3.4 WiringtheExternalDevice
(1) Remove the bush on the Lossnay unit and install a cable gland (with
two holes).
(2) Pass the external device cable connected to PZ-4GS-E and the
Lossnay unit power cable through the cable gland.
(3) Wire the external device by reference to Connection Diagram on the
next page.
Applicable cable: Multicore cable (strand wire, 0.5 mm2 (AWG 20))
* The gure below shows an example of when a ve-core cable is used.
(4) Wire the Lossnay unit power cable.
(5) Attach the control box cover as it was before.
Note
● If wiring for the Lossnay unit has been already done, switch the
cable gland from a one-hole cable gland to a two-hole cable gland
and install the power cable along with it.
● Use a cable gland that falls within the applicable cable range.
● ForwiringtheLossnayunitpowercable,refertotheLossnayunit
installation and instruction manual.

4. Electrical Work
WARNING
- Use a dedicated circuit for the equipment to be connected, and use
the voltage and breaker appropriate for the connected load.
- Connected equipment should be used within the rated voltage and
control capacity range.
- All electrical work must be performed by a licensed technician,
according to local regulations and the instructions given in the
Installation manual.

Lossnay operation,malfunction,By-pass ventilation,supply fan
operation,exhaust fan operation,Pre-heater signal, and supply fan
monitor output with delay operation (for after heater) signals can be
output from the TM3 terminal of the Lossnay unit control board and the
TM300 terminal of the PZ-4GS-E.

* Factory settings of Lossnay LGH-RVS series. The setting may di󰀨er
according to the type of Lossnay series. Be sure to refer each Lossnay
unit installation manual for detail setting.
The output signals from each terminal can be changed arbitrarily from
PZ-62DR-E.
In order to output the signals for pre-heater operation and supply fan
monitor output with delay operation (for after heater), a setting change
from PZ-62DR-E is necessary.
■ ConnectionDiagram
Note
● BecarefulthattheexternaldevicecablethatconnectstothePZ-
4GS-E do not touch the surface of the Lossnay unit control board.
It could lead to erroneous operation.
● Tighten the terminal block screws with a torque of 0.5N・m or less
to avoid damaging the circuit board.
● When connecting two cables to one location on the terminal block,
use a crimped terminal to ensure they are connected. Do not
connect three or more cables.
● Especially when using Pre-heater output signal or After-heater
output signal,refer to Lossnay installation and instruction manual.
