1. This product is intended for use only on data circuits with operating
voltages not to exceed 12VDC and DC power circuits with operating
voltages not to exceed 60VDC and operating currents not to exceed
10A.
2. Mounting the ALPU-TSU (See Diagram): Mount the device as close
to the equipment to be protected as possible using the provided hard-
ware and the concealed mounting holes. Mount the unit in the orienta-
tion shown, with the strain reliefs facing the ground.
3. Wiring the ALPU-TSU
3.1 The ALPU-TSU surge suppressor is bidirectional and may
be wired in either orientation.
3.2 Removing the Cover: Remove the 4 cover screws using a
Phillips screwdriver and lift off the cover.
3.3 Wiring: Thread a multiconductor cable from the data source
through one of the strain reliefs on the bottom of the unit. Strip back
the cable jacket as needed, then strip 1/4” off of each conductor.
Gently pull the terminal block off of the pcb pins, then install each
conductor into the corresponding screw-down location using the
callouts on the pcb and the color legend on the inside of the lid as a
guide. Finally, install the terminal block onto the pin strip by firmly
pressing it into place and tighten the strain relief onto the cable (Do
not over torque!!). Repeat this procedure for the outgoing multicon
ductor cable running to the equipment to be protected. Reinstall the
cover.
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!
