Installing and Connecting the Batteries
Installation
• Overcurrent protection for the AC branch circuit must comply with Article 760 of the
National Electrical Codes, as well as local codes.
• Use 12–14 AWG (3.31 mm
2
– 2.08 mm
2
) or larger wire with 600 VAC insulation for the AC
branch circuit.
Connect primary power as follows:
1.Turn off the circuit breaker at the main power
distribution panel.
2.Connect the earth ground terminal (TB1-
EARTH
) to a solid earth ground (a metallic, cold
water pipe may be suitable in some installations).
This connection is vital in reducing the panel’s
susceptibility to transients generated by lightning
and electrostatic discharge.
3.Connect the primary power neutral line to
terminal marked
NEUTRAL
and the primary power
AC line to terminal marked
HOT
.

WARNING: Risk of severe burns!
Batteries contain sulfuric acid which can cause severe burns to the skin and eyes, and can destroy
fabrics. If contact is made with sulfuric acid, immediately flush skin or eyes with water for 15 minutes
and seek immediate medical attention.
!
WARNING: Risk of equipment damage!
Do not connect the battery interconnect cables (P/N 75560, 75561, or 71070) at this time. Leave the
battery interconnect cables disconnected until after initial system power-up.
!
WARNING: Risk of equipment damage!
To avoid contact with metal cabinet, always install terminal bolts towards the center of the battery. See
Figure 2.18.
