5.0 BATTERY AND DC CONNECTIONS
WARNING
–
Only qualified personnel that are familiar with AC and DC installation
techniques and codes (such as an electrician) should perform the Installation.
WARNING
–
Remove all rings, watches, and other jewelry before doing any electrical
service or installation work. Always wear protective clothing and appropriate personal
protective equipment (PPE) that is suitable such as eye protection when working near
batteries.
WARNING
- Batteries contain tremendous energy and can explode if short circuited.
Precautions should be taken to eliminate possible short circuits. Do not install batteries
until unit is completely mounted and secured in a permanent location with all conduit
and AC wiring connected.
5.1 Battery Inspection
Inspect the batteries for any physical damage such as cracks or any other sign of
leaking electrolyte. Batteries contain Sulfuric Acid which is highly corrosive. A leak from
a battery will cause an unsafe condition.
5.2 Battery Installation
The E3MINI Series batteries may come pre-installed and pre-terminated to the main
DC Battery Connector. If battery connections must be made, follow detail in section 5.4
for the appropriate model you have.
Tip
- It is best to insert the jumper between both batteries before the batteries are fully
inserted into the supporting shelf. After ALL DC connections have been made, insert the
battery cable assembly’s multi
-pin connector into the mating plug on the right side of
the E3MINI Series electronics module. See section 5.4 for detailed illustrations.
5.3 DC Voltage of System
The systems DC battery voltage for the E3MINI Series is 24VDC for both 125W and
250W models. This voltage is produced by connecting two 12V batteries in series for the
125W model and a series parallel connection for the 250W model.
All required cables are provided by the manufacturer and may come pre-installed on
the batteries (model dependent). All batteries connect to a wiring harness in a fail-safe
manor to accomp
lish the system’s DC voltage
requirements.
NOTE
–
Battery potential does not have galvanic isolation from AC potential. Battery
Negative is tied to Neutral.
