Wiring
DC Terminal Connector Locations
Terminal connectors for DC wiring are located inside the wiring compartment.
The labels above the DC wiring terminals and inside the wiring compartment
identify all the connection points. See Figure 2-8.
Wire Size and Over-current Protection Requirements
The wiring, over-current protection devices (fuses and circuit breakers), and
installation methods used must conform to all national and local electrical code
requirements.
Wiring must be protected from physical damage with conduit or a strain relief
clamp.
To preserve signal integrity on communication cables, the BTS, auxiliary output,
and network cables must pass through a different conduit than the conduits used
for PV and battery cables. You should pull the BTS cable through the conduit first
as the connector may not fit if other wires have been pulled first.
Current Rating
The XW SCC PV input is rated for 60 A maximum I
sc
. Since PV outputs can vary
due to the array size or sunlight angle, the safe minimum wire size must be chosen
for maximum array short-circuit current. Consult PV array manufacturer
specifications.
Important:
Installations must meet all local electrical codes.
This equipment should
only be installed by a qualified electrician or a Certified Renewable Energy System
Installer.
WARNING: Shock hazard
Disconnect PV and battery circuits before wiring.
