Installation Manual

Installation

To install the DGP, do the following:
1. Mount the enclosure. A suitable location includes easy access for wiring, good lighting, suitable access
to power and earth ground, and ample space to work. The mounting surface should be flat and dry. We
do not recommend mounting metal enclosures directly onto concrete walls. Check with local
authorities to verify local codes regarding metal enclosure mounting.
All Alliance system enclosures contain four mounting holes located in the corners of the enclosure.
Use appropriate mounting hardware to mount the enclosure to the mounting surface and the batteries
to the enclosure as shown in Figure 1.
