Power Supply Rear Connections
The rear panel connections are:
Auxiliary Inputs –
The DE-9 connector on the T809-10 rear panel
provides access to the remote control and remote
sense functions of the power supply.
Output Voltage Adjust –
The output voltage of the power supply can be in-
creased (up to 18V approximately) to compensate
for the voltage drop lost along the cable. Access the
trim-pot through a small hole on the rear panel.
To adjust the output voltage use a trimmer tool with
a Phillips head or 3mm blade (do not use a stan-
dard flat blade screwdriver to make the adjust-
ment):
• To increase the output voltage, turn the trim-
pot clockwise.
• To decrease the output voltage, turn the trim-
pot counterclockwise.
If the output voltage is increased on a power supply
operating at, or close to, full load, the power supply
loading must be reduced accordingly or the module
may overheat and shut down.
Feedthrough Terminal Block –
The DC Output Terminal block on the rear of the
T809-10 is a Phoenix Contact HDFKV 10. This is a
screw-type terminal connector that uses a cage
mechanism to clamp the conductor(s). See section
2.5.1.1.1 for recommended torque settings.

Protective Bonding Terminal –
The Radio Assembly requires a secure ground connection. See section 2.5.1.1 for connection details.
120 VAC Connector –
Use the supplied 10A-rated IEC type power cord.
