2.2 Retrofitting PolluTherm F with an additional communication interface
To our calculator further communication interfaces can be added later.
Open the calculator by pulling the clamping bracket at the upper housing´s leading edge up.
Plug the interface module on the right side of the PC board. If there are module cables you have to loosen the needed number
of cable glands and to glide them over the cables. Remove the blind plugs from the cable gland openings and feed the cables
into the calculator.
Protect the calculator against unauthorized opening using one of the numbered adhesive seals enclosed to the modules (stick it
upon the seal destroyed). The added bar code label can be used for the purpose of documentation.
