How to install and wire the Plant Master
This section contains basic installation information, wiring specification and connection details.
The process of installing the Plant Master (NXTSD104) has 2 aspects:
Mechanical mounting
Electrical connection
WARNING
The Touch screen chassis earth point MUST be earthed to maintain
electrical safety and ensure reliable operation.
The screen of the CANbus cable is NOT designed to provide the earth
connection for the Touch screen display. Therefore, you must make a
separate earth connection using the largest cross-section area cable
possible.
4.1 Mechanical Mounting.
Mount the Touch screen on the front of the burner cabinet, or similar location. If possible, avoid
reflections from windows or boiler house lighting when planning the location of the screen.
The maximum allowable cabinet wall thickness is 0.28 " (7 mm.)
Install the Touch screen so that the part within the panel is in a PD1 or PD2 environment according
to EN6730-1, and the ambient operating temperature range of the equipment is 32 to 140 °F
(0 to 60 °C).
With the sealing gasket installed between the panel and the Touch screen, the protection from
‘outside’ the panel will be IP65.
4.2 Wiring Requirements.
Please pay particular attention to the wiring requirements for the Plant Master. These will protect
the equipment from electrical interference, earth loop problems, and damage to the controller and
modules.
