Memory card
If a memory card is to be used with the Control Unit (CU), then the memory card must be
inserted into the CU prior to being fitted on the Power Module (PM). Once the CU is fitted to
the PM it is not possible to insert a memory card into the CU.
The Control Unit (CU) is snapped onto the Power Module as shown in the figure below. The
CU is fitted in the following sequence:
1. Angle the CU to allow the lower hooks of the CU to fit into the lower recesses of the
Power Module (PM).
2. Push the top of the CU towards the PM until it clicks into place.
