7.6 Wiring
All inter-connections between circuit boards, blowers and sensors are
made at the factory. Remove link wire if switched live signal, an enabler
or BMS signal is connected.
If inlet and outlet dampers are fitted, remove the damper link
wires. This will allow a 1 minute delay before starting the fans.
A series of basic connection wiring diagrams have been provided to
assist on-site wiring. In order to reference the relevant diagrams please
use the code breakdown opposite to determine:
•
Unit size
•
If an electric heater is present
•
If a LPHW heater is present
The below tables can then be used to reference the required connection
and wiring diagrams.
Example:
Unit on site has code
B822V/EN/ES-L.
