Compliance, safety, and intended use
44Alvium G1 User Guide V1.7.0
Cable connections
Provide sufficient strain relief for all cable connections to avoid short circuits and
malfunctions.
Camera power
Operating the camera beyond the specified range damages the camera.
Cameras can be powered using the I/O connector at an input range of 12 to
24 VDC, using a limited power source (LPS), according to IEC 62368-1 with
minimum 2.0 A. The camera is not intended to be connected to a DC distribution
network.
Alternatively, cameras can be powered over Ethernet. However, power
consumption and heat generation are higher than with external power, using the
I/O connector.
• Never use PoE and external power at the same time. Otherwise, the camera
is damaged.
• Make sure that PoE power sourcing equipment is at least compliant to
IEEE 802.3af.
• Only use power supplies that meet the insulation requirement according to
PELV or SELV. For details, please refer to IEC 61140.
• If using external power supplies by third-party manufacturers, observe polarity
to avoid damage to the camera electronics.
PoE Power Sourcing Equipment (PSE)
Damage to the camera or connected peripherals can occur if PSE is not galvanically
isolated from mains and other electrical connections towards the camera (other
than Ethernet signals and shield ground).
To avoid damage
• Never use PoE and external power at the same time. Otherwise, the camera
is damaged.
• Only use IEEE802.3af/at compliant PSE equipment to power the camera via
PoE.
• Ensure the PSE is galvanically isolated from mains and all other electrical
connections towards the camera.
PoE versus external power
Powering the camera via PoE results in higher power consumption and heat
generation than external power, resulting in higher energy costs and requiring more
efficient heat dissipation.
External power supply
For the 13870 10-pin TFM power supply, see www.alliedvision.com/en/support/
