DC MODELS
Note: DC models include one four pin terminal block connector
which supports both NEC CLASS1 and CLASS2
• CLASS2 (default) – supported by the four pins of the DC
terminal block connector for remote feed supporting two DC
wiring pairs
• CLASS1 – supported by the first two pins (LT-to-RT) of the DC
terminal block for local plant feed. To use CLASS1 – user must
change default connector mode from CLASS2 to CLASS1 (see
"Local plant feed – CLASS1 connector" description).
Remote feed – CLASS2 connector (default)
DC CLASS2 connector specs:
• Supported wire AWG:
– Conductor cross-section, solid (AWG/mm²):
30~12/0.2~2.5
– Conductor cross-section, flexible (AWG/ mm²):
30~12/0.2~2.5
• Wire strip length: 9~10 mm
DC Power input: 30-60 VDC
Power amplifier consumption per pair:
• First pair: 50 W
• Second pair: 78 W
Maximum power consumption: 131 W
Maximum current consumption:
• First pair: 2.1 A
• Second pair: 3.3 A
Local plant feed – CLASS1 connector:
Step 1:
Open PSM captive screws and pull-out module
from chassis.
Step 2:
Remove PSM-DC top panel by unsrewing the three
screws on each side panel, as shown in Figure 6.
Step 3:
Disconnect DC input source type connector
and reconnect with the arrows pointing to the
"CLASS1" setting. See Figure 7.
Step 4:
Close top panel and insert PSM-DC in chassis
slot.
Step 5:
Route DC pair from the first two DC CLASS1
connector to local power source.
Power input: 48 VDC (40-60 VDC) 9 A maximum
