Connect the AXIS PS12 Outdoor Power Supply
This guide provides instructions for connecting and preparing the AXIS PS12 Outdoor
Power Supply for use. This product is designed for use with Axis products which have a
power-in terminal connector. The AXIS 225FD is one example.
Primary Cable Secondary Cable
Important!
• Read through the instructions before starting the installation.
• All electrical connections and adjustments should be made by an authorized
electrician.
• Please observe relevant national and local regulations for the installation.

Extend the length of the secondary side cable
The power supply is delivered with a 5-meter cable on both the primary and secondary
sides, (see the illustration). The primary cable must be fitted with the appropriate
country-specific plug.
Cables may be shortened or lengthened to fit the application. If the secondary cable needs
to be more than 5 meters (the original cable length) or if more than one product is to be
connected, follow these recommended instructions:
Cut the secondary cable to a maximum length of 25cm. This length will minimize the
voltage drop in the shared part of the cable.
Split the secondary cable and connect it to the cable(s) that will run to your unit(s) - one
cable for each connected product.
• Use an appropriate splitter/connec-

tive, weather-tight conduit.
Important!
• The total maximum current consumption for all connected products must not exceed the PS12 maximum
output current limit (4.5A).
• Use cables and conduits suitable for the installation and that are in compliance with the IP67 rating.
• Note that if your installation is to be vandal resistant, you will also need to make sure all cable conduits are
vandal resistant.

Calculate the maximum extended cable length
Use the formula below to calculate the maximum extended cable length (Lmax in meters)
for each connected device. The formula uses the cable resistance of 18AWG (same cable
dimension as the secondary cable). It is recommended that you use this cable dimension or
thicker.

• You may need to substitute the power cable which was supplied with your Axis product
with a new cable of minimum 18AWG (not included). Only do this if the camera you
are attaching has a power-in terminal connector.
Connect to the AXIS 225FD when using the Built-in Heater
To prepare the AXIS PS12 Outdoor Power Supply in conjunction with the AXIS 225FD
when you are using the built-in heater, please follow these instructions. A maximum of
three AXIS 225FD cameras can be connected to the PS12. The AXIS 225FD power
consumption with active heaters is 16.5W at 12VDC.
1. Cut the PS12 secondary cable to a maximum length of 25cm.
2. Connect one extended cable for each connected AXIS 225FD, see Calculate the
maximum extended cable length. Be sure to use cable dimension 18AWG or thicker.
