Note:
There are no ON/OFF circuit breakers/switches on the VMG-14+ AC system. Once the system is
cabled and connected to the site power source, the system powers up as associated with power-
up of the source.
Circuit breakers will be provided on the DC PEMs for the VMG-14+ DC system.
AC System Power
An AC power system consists of four AC PEMs and four AC power supplies. Each PEM provides
AC power for the individual AC power supply units (PSUs) directly in line at the rear connection. For
normal operations, all PSUs should be present. An alarm is generated and reported at the VMG Element
Manager if any are removed.
The AC PEM does not contain status indicators or control features, and does not communicate with the
SCM. However, all communications with the AC power system occur between the AC PSUs the SCM.
The SCM monitors each power supply for presence and operational status. Status indicators are
provided on the AC PSU
The VMG-14+ AC system uses Imagine Communications-supplied power cords. Ordering information
is provided in the
Overall input specifications per AC PSU are 209-240V, 14-10A, 12-7A, 47-63Hz.
