Input Fault Detection and LEDS
On the PIM there is a voltage monitor for input voltage detection. If the input voltage after the
fuse is missing or too low, an alarm is forwarded to the CU on the LU1, and a LED indicates the
input voltage status.

Cabling
The PIM can be used with normal copper power cables as screw terminals are used. The maximum
conductor cross section is 25 mm
2
(solid), 16 mm
2
(stranded) and 16 mm
2
(with ferrule). The
router can be wired with either single power cable pair or two pairs of cables if thinner cable is
preferred in the installation.
Also a grounding cable with the same or thicker cross-sectional area than the power cable must
be used with the 8665 Smart Router subrack with PIMs installed; that is, at least 16 mm
2
(approximately 5 AWG) or 25 mm
2
(approximately 3 AWG). For more details on power and
grounding cabling, please refer to
