4 Installation
4.1 Pre-installation considerations
The information in this section is intended to be used as a guideline only. There may be site-specific requirements
and other factors that may require different procedures. For example, your jurisdictional codes and construction
covenants may require different procedures than those in this manual.
4.2 Power system
An Alpha system provides sufficient power for a defined frame load plus the capacity to recharge the batteries
within 24 hours.
“N+1 recharge” time refers to the estimated hours to recharge the batteries to 95% while operating at full load with
all the rectifiers working and where
a “redundant” rectifier is installed. Consult the factory if your equipment
configuration has changed from its original layout.
4.3 HVAC system
The 4000 BTU air conditioning/heater and the emergency ventilation system are optimized and tested for a
particular equipment configuration within the enclosure. Consult the factory if your equipment configuration has
changed from the original layout. Factory testing may be required for new equipment configurations.
4.4 Site selection
The Te45 has been designed as an outdoor power system enclosure. The most common mounting structures are:

An at-grade concrete slab.

A steel platform.

An existing structure, such as a rooftop.
The mounting structure must be strong enough to support a fully equipped enclosure. Existing structures may need
to be reinforced to support the enclosure. The mounting site must be built in accordance with local building
practices and codes. A fully equipped power enclosure with 5 rectifiers and 8 batteries weighs approximately 2000
lb. A fully configured power enclosure with 16 batteries weighs approximately 3000 lb.
Consider the following before selecting a mounting site:

The Alpha Te45 enclosure is designed for front, rear, and if necessary top access. Only front access is required
for maintenance.

Avoid areas that may be subjected to hot air exhaust from nearby equipment or buildings.

Find out if your intended area is subjected to architectural controls or environmental restrictions.

Avoid areas that are prone to flooding.
4.5 Enclosure support
A supporting structure with a minimum load capacity of 350 lb/ft² is required to support a fully equipped power
enclosure with rectifiers, batteries, air conditioner, etc.
A support structure with a minimum load capacity of 500 lb/ft² is required to support a fully equipped battery
enclosure.
