Installation Instruction

9. Notice: Use an appropriate torque wrench for the coupling torques:
- for N-type connectors (2 N-m / 20 in lb) with 13/16 in opening,
e. g. item no. 244379 available from the CommScope e-catalog
- for 7/16 DIN-type (25 N-m / 19 ft lb) with 1 ¼ in opening,
e. g. item no. 244377 available from the CommScope e-catalog
- for 4.3-10 type connectors (5 N-m, 44 in lb) with 22mm (7/8) in opening
Do NOT use your hands or any other tool (e.g. a pair of pliers). This might cause damage to the
connector and lead to a malfunction of the Extension Unit.
10. Notice: For unstabilized electric networks, which frequently generate spikes, the use of a
voltage limiting device is advised.
11. Notice: Observe the labels on the front panels before connecting or disconnecting any
cables.
12. Notice: Unused connectors must be closed with their protective covers to ensure
watertightness.
