PowerA and PowerB Connectors
Molex-style connectors are used to provide –48 VDC (labeled
POWERA
and
POWERB
). When the unit is successfully powered, the PWR LED near the left-side
of this panel illuminates green. If the power connection is reversed, the unit will not
be damaged, it simply will not power-up. Startup power will be less than 9.2 watts.
Steady-state power (at a nominal temperature of 25° C) is less than 5.3 watts.
The TimeProvider 500 uses –48 VDC power and is not equipped with a power
switch. Power to the unit must be controlled by a Branch Circuit Over-Current
Protection Device to the DC power main.
Warning:
To avoid serious personal injury or death, exercise caution
when working near high voltage lines and follow local building
electrical codes for grounding the shelf.
