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.
- Use the specified cables for wiring and connect them securely.
Hold the cables so as not to apply external force of the cables to
the Terminal block of this product.
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 differ
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.
