Section 3 — Hardware Installation
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 correctly.
The pinouts are shown on Table 26 on page 170. An illustration of the
power connectors is shown on
Figure 68 on page 141 .
The power supply modules are factory-installed and designed to be
hotswappable.
Note Fuses must be selected and installed as appropriate for mains voltage. It is
important that you refer to the Trinix rear panel’s frame markings for the
correct Fuse value and Power requirements.
For systems with only one power supply, the RP-33500 512 x 512 Rear Panel
card jumper JN1 must be set to DC, otherwise the Alarm LED on the frame
front panel will remain on. If a redundant power supply is installed later,
the JN1 must then be moved to AC. See
Figure 94 on page 179 .
DC Applications
In DC applications, the TRX-NXT-512x512 may not include a separate
power supply frame. When a separate power supply frame is used:
1. Connect the DC source to the DC Input 1 and DC Input 2 connectors of
the PS frame.
2. Use the supplied cables to connect the DC Output 1 and 2 connectors of
the PS frame to the DC Input 1 and DC Input 2 connectors of the main
frame. Pinouts are shown on Table 26 on page 170.
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 frame, connect the DC source directly to the DC Input
1 and DC Input 2 connectors of the main frame.
Note For DC applications, fusing must be provided externally in accordance
with local electrical regulations. DC input specifications and characteristics
for the Trinix are shown in the
DC Power Input section.
An illustration of the power connectors is shown on Figure 68 on page 141 .
Check to see that the RP-33500 512 x 512 Rear Panel card has jumper JN1
set to DC. See
Figure 94 on page 179 .
Simultaneous AC and DC Applications
It is possible to connect both AC and DC power sources as part of a system
redundancy scheme. In this case, refer to the AC and DC notes above. RP-
33500 jumper JN1 should be set to AC.
