NPPA-TT-S Instruction Manual 2. Replacement of Jack Pairs Each individual jack pair can be exchanged quickly and without fuss even while the panel is "on air". For replacement simply remove the easy accessible jack pairs. Module consisting of 2 Jack Pairs Remove Front Panel by unscrewing the 3 black cross-recessed screws (M3x8 Taptite), remove the two side-stops. Push out the channel identification strips.
NPPA-TT-S Instruction Manual The two jack pairs have to be re-assembled in the right way so that the thicker body marked “left” is put on the left side with the mark outside and readable. To complete, push the new jack pairs into the casing again with the mark on the left side (If more than one module are removed always assemble from the center to the right or left side and be careful that the keys on the left side of the jack pairs find their guiding slots.

NPPA-TT-S Instruction Manual 4. Grounding variations The flexible grounding system provides the following versions: Individual: Group: Central: Chassis-Common: Each channel is individually grounded by its corresponding cable shield (default configuration). Selected channel grounds are connected via the ground bus on the PCB using solder bridges and track cuts to form a group that is connected to one common cable shield.
NPPA-TT-S Instruction Manual Grounding Variations NOTE: In standard configuration there is no ground connection between top and bottom row unless it is provided by an inserted patch cable.

Cable retention to the unit The built in cable retention bar is at the back of the casing. Simply attach the cables with cable ties to the bar as shown in the photo. For large and heavy bundles there is an additional strain relief bar NPPA-S available. It is attached to the casing with four screws.
NPPA-TT-S Instruction Manual 7. Channel identification The front panel is equipped with channel identification strips located in the center of the channels and marked with the channel numbers 1-24 and 25-48 respectively.
