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 page 106. An illustration of the power connectors
is shown on page 102.
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 page 122.
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 page 106.
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 page 80.
An illustration of the power connectors is shown on page 102.
Check to see that the RP-33500 512 x 512 Rear Panel card has jumper
JN1 set to “DC.” See page 122.
