3.1.6.1 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 of the power
supply (reserved for future use).
• Output Voltage Adjust –
The output voltage of the power supply can be increased (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
standard flat blade screwdriver to make the ad-
justment):
• 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 sup-
ply 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 de-
tails.
• 120 VAC Connector –
Use the supplied 10A-rated IEC type power cord.
