### Choose a mounting location
{% hint style="info" %}
Before selecting a mounting location, review [Safety information](/hera604/reference/safety-information.md).
{% endhint %}
Make sure the location meets these requirements:
1. Choose a stable, weather-protected location free from vibration.
2. Check cellular and Wi-Fi signal strength, and avoid nearby equipment that can cause interference.
3. Keep the antenna connectors, cable connections, and LEDs accessible.
### Before you begin
You need these tools:
* Security Torx screwdriver with a T10 tip
* Tape measure, spirit level, pencil, and masking tape
* Cross-head Pozidriv or Phillips screwdriver
* Drill with an Ø 5 mm or Ø 3⁄16 in bit
You need these fixings:
* Four plastic wall plugs: Ø 5 mm × 30 mm or Ø 3⁄16 in × 1¼ in
* Four pan-head wood screws: Ø 3.5 mm × 30 mm or Ø #6 × 1¼ in
### Mount the Hera
{% stepper %}
{% step %}
#### Fit the SIM
The socket uses a push-to-insert, push-to-release mechanism, so the SIM clicks into place and sits flush with the edge of the SIM slot.
If a SIM card is supplied with your Hera, insert it fully into the SIM card slot.
{% endstep %}
{% step %}
#### Fit the SIM card security plate
Use a Security Torx screwdriver with a T10 tip to fit the security plate across the Hera SIM card slots.
{% endstep %}
{% step %}
#### Mark the mounting points
Choose one marking method:
{% tabs %}
{% tab title="Use the template" %}
1. Print the drilling template supplied with the router.
2. Measure the printed template. Printing can change its scale.
3. If the template is accurate, level it against the wall.
4. Secure the template with masking tape.
{% endtab %}
{% tab title="Mark directly" %}
1. Hold the Hera against the wall.
2. Mark the drill holes.
{% endtab %}
{% endtabs %}
{% endstep %}
{% step %}
#### Drill and fit the wall plugs
Drill the four marked holes, then fit a wall plug into each hole.
{% endstep %}
{% step %}
#### Attach the antennas
Connect the LTE 1 and LTE 2 cellular antenna cables, then connect the Wi-Fi antennas.
{% endstep %}
{% step %}
#### Position the Hera
Position the Hera over the mounting points.
{% endstep %}
{% step %}
#### Secure the Hera
Secure the Hera with the four screws.
{% endstep %}
{% step %}
#### Position the antennas
Position the antennas for optimal performance.
{% endstep %}
{% step %}
#### Connect power
Connect the power connector to the Hera, then connect the mains adapter to a dedicated socket.
{% endstep %}
{% step %}
#### Switch on power
Switch on the mains supply.
{% endstep %}
{% endstepper %}
Secure the cables and antennas to prevent intermittent connections.
Confirm that the Power LED is solid green. Confirm that either the LAN or WAN LED is solid green.
To complete setup, [connect Hera 604](/hera604/get-started/connect-hera-604.md), then [log in to Hera 604](/hera604/get-started/log-in-to-the-hera-604.md).
### Disposal
{% hint style="info" %}
In accordance with EU Directive 2012/19/EC, separate this product and its accessories from other waste and scrap at end of life. Deliver them to the WEEE collection system in your country for recycling.
{% endhint %}

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://docs.eseye.com/hera604/physical-specifications-and-mounting.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
