Mounting requirements

The Hera 204 supports direct mounting and bottom or side DIN rail mounting using an optional mounting kit.

Choose a location that:

• Is away from direct sunlight and other heat sources.
• Provides sufficient ventilation around the router.
• Is not exposed to excessive dust, liquids, or industrial exhaust.
• Is within one metre of a mains power outlet.
• Keeps cellular antennas at least one metre away from people during normal operation.
• Allows access to the router’s ports, SIM slot, and reset button.

Do not mount the Hera 204 more than two metres above the floor. A falling router could cause injury.

The supplied antennas are not designed for outdoor use. If you use an outdoor antenna, ensure adequate lightning protection.

Use only an Eseye-approved Limited Power Source mains adapter. It must comply with IEC/UL 60950-1 or IEC/UL 62368-1. Do not modify the power adapter.
