DV-33512 Chassis Installation
AC applications
Power supply modules for 512 x 512 switchers are mounted in a sepa-
rate chassis and require cabling (supplied) from the “DC Output 1" con-
nector of the power supply chassis to the “DC Input 1" connector of the
switcher chassis; and from “DC Output 2" to “DC Input 2."
CAUTION Do not cross these cables. Output 1 must go to Input 1 and Output 2
to Input 2 in order for the alarm system to operate properly.
Pinouts are shown on
. An illustration of the power connectors
is shown on
The power supply modules are factory-installed and designed to be
hot-swappable.
Note
Fuses must be selected and installed as appropriate for mains voltage.
For systems with only one power supply, RP-33500 512 x 512 Rear Panel
card jumper JN1 must be set to “DC,” otherwise the Alarm LED on the
chassis front panel will remain on. If a redundant power supply is
installed at a later time, JN1 must be moved to “AC.” See
.
DC Applications
In DC applications, the DV-33512 may or may not include a separate
power supply chassis.
When a separate power supply chassis is used:
1.
Connect the DC source to the DC Input 1 and DC Input 2 connectors
of the PS chassis.
2.
Use the supplied cables to connect the DC Output 1 and 2
connectors of the PS chassis to the DC Input 1 and DC Input 2
connectors of the main chassis. Pinouts are shown on
.
CAUTION Do not cross these cables. Output 1 must go to Input 1 and Output 2
to Input 2 in order for the alarm system to operate properly.
When there is no PS chassis, connect the DC source directly to the DC
Input 1 and DC Input 2 connectors of the main chassis.
Note
For DC applications fusing must be provided externally, in accordance
with local electrical regulations. DC input specifications and character-
istics for the Trinix are shown on
.

Check to see that the RP-33500 512 x 512 Rear Panel card has jumper
JN1 set to “DC.” See
