The +12Vdc output is derived from the 3.3Vdc output, and the -12Vdc output is derived
from the 5Vdc output. The +/- 12Vdc outputs are capable of providing up to 500mA,
however, they must be de-rated to avoid exceeding the maximum power limits of the
3.3Vdc and 5Vdc outputs respectively.
6.3.1 Environmental
Operating Temperature: -40C to 70C
Relative Humidity: 0-95% non-condensing
Installation Category: IC III (Distribution Level), Pollution Degree 2. Refer to definition
on page 9.
6.3.2 Physical
Input Connections: Removable terminal block accepts #26-12 AWG (0,15-3,3mm
2
)
wire, or terminal lugs up to 0.325" (8,25mm) wide.
Recommended minimum wire size is #18 AWG (0,5 mm
2
).
Recommended Torque Rating for the terminal block wire
fasteners is 10 In-Lbs, 1.13N-m. Precautions must be taken to
prevent shorting of lugs at the terminal block. A minimum
distance of 0.1” (2.5mm) is recommended between un-insulated
lugs to maintain insulation requirements. Standard 0.200"
(5,08mm) header socket accepts other standard terminal types.
Backplane Connections: Standard cPCI-specified power connector
