2.5 Making DC Output Connections

Installer is responsible to provide suitable dc output, battery, and dc
load wiring.
Follow these steps to connect the battery to ATevo:
1. Size the dc wiring to minimize voltage drop. Acceptable wire
size depends on the installation. As a guideline, voltage
drop should not exceed 1% of nominal output voltage at
full current. Refer to the following table to determine the
voltage drops for various wire sizes, currents and distances.

EXAMPLE:
2. ATevo is factory wired to regulate output voltage at the
output terminals. If total voltage drop is greater than 1%
(e.g. 1.3V for a 130 Vdc system), remote sense wiring is
recommended (see Section 11).
3. Do not run external ac and dc power wiring through the
same conduit.
4. Facility-specific installation requirements take precedence.
