The product is powered up by pressing the Power switch located inside the product
towards the bottom right-hand side (see Figure 5—1). The mains fuse holder for the

Note: The product automatically turns on the internal heaters to increase the internal

can commence.

5.2 LED status indicators

The product has two relays — a service relay and a caution and alarm relay — and two
corresponding external sunlight-visible red and green LEDs on the front door. When the
product is connected to the mains power and is powered on, the green LED illuminates
continuously. Each LED has three states – Off (-), On or Flashing, the meaning of which is
defined in Table 5—1.
