6. Wiring the controller hardware modules
6.1 Introduction
6.1.1 Introduction
This chapter describes the wiring for each of the controller hardware modules in detail. Each terminal's wiring is described, with
examples. Wiring the CAN bus communication to a genset is also included in this chapter. However, wiring the system
communication (including the connection to the display unit) is described in another chapter.
The Data sheet contains all the technical specifications for all the terminals.
The default wiring for the controller type is described in the chapter Default wiring for controller types.
DANGER!
You must only use the terminal blocks supplied with the controller and display unit. Do not use substitutes.
