1. This product is intended for use only on data and DC power circuits with
operating voltages not to exceed 55VDC and operating currents not to exceed
1A.
2. Mounting the ALPU-EXLT (See Diagram): Mount the device as close to the
equipment to be protected as possible using the provided hardware and the
concealed mounting holes. Mount the unit in the orientation shown, with the
marking “UP” facing upward and the strain reliefs facing the ground.
3. Wiring the ALPU-EXLT
3.1 Removing the Cover: Loosen the 4 captive cover screws using a Phil
lips screwdriver and lift off the cover.
3.2 Wiring the Suppressor: Thread a multiconductor cable from the data
source through the strain relief adjacent to the marking on the PCB la
beled Input. Strip back the cable jacket as needed, then install the conduc
tors into the IDC connectors labeled Input using the following technique:
Lay the wires into the grooves in the connector, leaving approximately
1/8” of wire overhanging, and press down firmly with the punch-down tool
provided in the packaging supplies until the wires firmly engage into the
fork terminals. Use the wiring tables in this document as well as the call
outs on the PCB as a guide. Repeat this procedure for the outgoing `
multiconductor cable, using the connectors labeled Output. Tighten the
strain reliefs to secure the cables (DO NOT OVER TORQUE!!). Reinstall
the cover.
3.3 The ALPU-EXLT is compatible with Exalt r-series radios, as well as any
other radio systems with the electrical service characteristics given in note
1.
3.4 Grounding: Connect the external ground lug on the enclosure to a solid
Earth ground. The unit must be grounded for the suppressor to operate
properly!
