10.3 Workmanship
Workmanship, including ANSI/IPC-A-620 soldering, is designed to meet ANSI/J-STD-002 and
RTCA/DO-254.
10.4 Safety
The Sierra includes fuses on the system input power lines (Shurter Inc. P/N: 3413.0331.22, 63V, 20A),
as well as additional fuses on the input power lines to the main system circuitry (Littelfuse P/N:
RUEF300K-2, 30V, 3A), both to protect against over current conditions.
The Sierra is also be equipped with a temperature sensor (Texas Instruments P/N: LM75BIMM-
3/NOPB) that can monitor the unit’s internal temperature and be configured in software to inhibit
operation in over-temperature and under-temperature conditions.
Furthermore, Sierra is equipped with two (2) (optional) Lithium Ion rechargeable Smart Battery Packs,
which includes a management and safety unit to protect against under voltage, over voltage,
overcurrent, over temperature, and short circuit conditions. The batteries comply with UL2054:2011 /
UL1642:2009 and IEC62133:2012.
