4.0 – Installation & Wiring

This section covers how to install the PHI 3.8 batteries within the AccESS unit, torque values, communications

and network preparation and how to wire the AccESS unit. It also provides guidance on how to install optional

AccESS unit components/accessories.

4.1 – Basic System Configuration Concepts

Safe and reliable installation requires trained and certified technicians. The following discussion is a basic primer.

Due to the variety of systems and components in the field, all possible scenarios are not covered. This is not the

purpose of this section of the manual. Refer to professional installers regarding your system and its components

and specifications. We encourage you or your installer to contact us with any specific questions for technical

support. We are committed to working with you and your installation team to achieve a safe, reliable storage

system that will provide years of maintenance free service.

4.2 – PHI 3.8 Battery Installation within the AccESS

1. Mount the AccESS unit on level concrete.

2. Make sure all PHI battery module circuit breakers are in the OFF position. Prepare the battery

modules for installation by removing all plastic terminal covers, 11/16” stainless steel hex nuts and

3/8” lock washers from the batteries’ terminals and set aside.

CAUTION: Do not attempt to loosen the large brass nuts at the base of the battery terminals.

MISE EN GARDE: Ne pas desserrer le gros écrou en laiton à la base des bornes; cela endommagerait la

Batterie PHI et Annulerait la Garantie.

3. Place two PHI 3.8 batteries in the bottom of the cabinet and arrange two or three PHI 3.8 batteries on the

AccESS’s internal shelf. Orient the modules so that the battery terminals point toward the AccESS

door, with the negative posts nearest the bottom of the AccESS enclosure. Refer to Figure 11.0a and

11.0b below:
