6. LPS04 Installation
This chapter is provided for qualified personnel to install an LPS04 system.
6.1 General Instructions
This chapter provides cabling details and notes on cable sizing for DC applications.
Connections to the converter system must comply with all the local codes and ordinances.
6.2 Safety Precautions
WARNING!
The DC input to the modules (and the converter system) – though not dangerous in volt-
age – has a high short circuit current capacity that may cause severe burns and electri-
cal arcing.
The DC output is a potentially dangerous voltage. Do not touch the output connections
when under power. Per GR1089-ClassA2, qualified technicians can work on the unit
when energized.
Before working with any live power system, take the following precautions:
•
Remove all metallic jewelry; e.g., watches, rings, metal rimmed glasses, necklaces.
•
Wear safety glasses with side shields (and prescription lenses if necessary) at all times during installation.
Use insulated metallic tools.
The installer should follow all applicable local rules and regulations for electrical and battery installations; e.g., CSA,
UL, CEC, NEC, OSHA, and local fire codes.
6.3 Tools Required
Various insulated tools are essential for product installation. The following list is a guide:
•
Phillips head screwdriver, #2 (tip size 3/16")
•
Slot head screwdriver (blade size 1/8")
•
Digital voltmeter equipped with test leads
•
Cutters, crimpers, and wire strippers 0.25 to 10mm

(#24 to #6 AWG)
6.4 Mounting
The following figures show the two recommended mounting orientations. For more detailed information refer to
0120037-08 drawing at the back of this manual.
Recommended hardware:
•
4x #12 to 1/4" screws or bolts
•
4x #12 to 1/4" flat narrow washers with 0.75" OD max.
•
4x #12 to 1/4" sealing washers for watertight mount
The LPS04 can be mounted to surfaces with #12 (MG) to 1/4-20 fastening hardware in four locations. Alpha recom-
mends using flat washers for improved fastening.
The LPS04 unit shall be continuously energized to prevent condensation within the en
-
closure.
