Danger!
Opening and setting of the instrument may only be done after having switched-off the
supply voltage, and by observing the instructions as given in chapter 2.
5.1 Opening the instrument
Note: Upon delivery from the factory the instrument is not completely closed. Sliding of the
electronic part (1) into the housing will be prevented by a small sponge.
Changes of the solder links can be done on the interface card (PCB 2)
(see chapter 5.3.1).
After setting the instrument the small sponge has to be removed.
The instrument must be opened carefully by spreading out slightly the side parts of the housing (2),
without breaking them. This can be done by using e.g. a small screwdriver. As soon as the little plastic noses
become released pull out the electronic part (1).
After opening, the power supply card (PCB 1), and the interface card (PCB 2) become visible.
Both cards are fixed to each other by means of 3 bolts and interconnected via flat cable connection.
