4.2 CABLE PASSAGE THROUGH THE EQUIPMENT FRAME Remove the plastic caps from: ZONE A: display zone; where the display unit bracket is fixed; ZONE B: power supply input zone (3 caps to be removed); ZONE C: weight stack zone; using a flat screwdriver. When the plastic caps are removed for cable passage, it is recommended to always use a piece of packaging plastic to protect the equipment frame from damage.
Page 14
The cable supplied in the kit consists of the following connectors that must pass through the equipment frame, as follows: CONNECTOR 1 - “male” connector towards the weight stack sensor bar: pass CONNECTOR 1 through the hole of the display zone and make it exit from the weight stack sensor zone. (follow the cable passage procedure indicated below).
Page 15
When passing the cable through the equipment frame, use electrical tape to protect the parts not protected by the outer cable mesh. Proceed as follows to make CONNECTOR 1 exit from the weight stack sensor zone: Connect CONNECTOR 1 and CONNECTOR 2 to the fairlead spring, using electrical tape. Pass the fairlead spring from the hole located in ZONE A (display zone) to the hole located in ZONE B (power supply input zone) and make the cable exit.

Page 22
Position the weight stack sensor bar in the bottom of the guide of the additional weight. The distance from the bottom between the end of the guide of the additional weight and the weight stack sensor bar must be 4 cm – 1.57’’. Fasten the weight stack sensor bar to the guide of the additional weight.
Page 23
Fasten the 2 guides of the additional weight and the additional weight support plate to the rear guard, as done originally. TOOL: 13mm socket wrench. The nuts of the guide of the additional weight are self-locking. The nuts of the additional weight support plate are normal.
Page 24
Connect the additional weight sensor cable (CABLE C) and the weight stack sensor cable (CABLE D) to the weight stack sensor bar. Connection of the cables to the weight stack sensor bar: the connection shown in red should be avoided, as the contacts present in the sensor bar are very small and can be easily bent/damaged.
