Powering
NOTE! To reduce the risk of electric shock, do not remove the
shielding cover of the power supply unit if it is connected. All
electrical installations must be carried out by authorized and
competent technicians in accordance with the national or regional
electrical regulations.
Common precautions:
• The AC1500 amplifier is intended for installation in restricted access
locations (dedicated equipment rooms, equipment closet, or the like)
• Operate the device only on the specified supply voltage.
• The AC1500 must never be operated without its power supply unit
shielding cover.
• The AC1500 has no separate power switch thus the power plug must
be easily accessible.
• Disconnect the power cord by the connector only. Never pull on the
cable portion of the power cord.
• Do not place or drop heavy or sharp-edged objects on the power cord.
• The power must be disconnected when installing or removing the
AC1500.
The AC1500 can be powered by several PSU options. Every option has its own
advantages and limitations which are described briefly as follows.
230 V AC:
The locally powered AC1500 amplifier is connected to the mains voltage of
205…255 V AC via its own power cord. The power supply unit (AC6313) is
double shielded and does not require separate grounding. However, ensure that
the housing of the AC1500 is properly connected to the earth in order to meet
safety requirements. Proper grounding will also improve protection from the
effects of interference and thus increase the overall reliability of the system.
27...65 V AC:
The ACE6314 power supply unit accepts 27...65 V AC either via a coaxial cable
by inserting a fuse to the corresponding fuse holder or directly at the external
input. The external input is located on the power distribution board at the upper
right corner of the node. External power can also be fed through the node into
the network. Maximum feed-through current is 7 A per port (15 A total). If
powering will be provided through a dedicated output port, the port must be
equipped with a fuse (supplied).
40...90 V AC:
The node can alternatively be delivered with a 40...90 VAC (square or quasi
square) for remote supply. Power is supplied either via a coaxial cable by
inserting a fuse to the corresponding fuse holder or directly at the external input.
The external input is located on the power distribution board at the upper right
corner of the node. External power can also be fed through the node into the
network. Maximum feed-through current is 7 A per port (15 A total). If powering
will be provided through a dedicated output port, the port must be equipped with
a fuse (supplied). Note! This PSU option (AC6315) is not fully compliant with the
EN 60728-11:2010 standard because powering voltage can exceed 65 V AC.
