Precautions

The following precautions and checks are applicable to all mounting types:-

1. Leave blanking plugs over all connectors until they have been connected to the

appropriate cabling. These plugs are specially fitted to keep moisture and

contaminates out of the unit.

2. Connectors have been manufactured to fit their specific cables. Do not modify or

force connectors.

3. Check Site Plans for engineering approval.

4. Ensure that good ground resistance is available at the installation site (<2)

5. Do not attempt to install in rain.

6. In adverse weather conditions care should be taken before work commences.

7. Where the Node B is mounted in an outdoor application the fixings sourced locally

should be stainless steel A2-304 or equivalent.

Direct Wall Mounting

Direct wall mounting requires the following materials:-

1. Drill template - supplied with Node B

2. 4off M8x55L Rawlok Loose bolt or equivalent eg. Hilti anchor bolts - locally supplied

3. Drill & Masonary Drill Bit

Position template and drill holes through template at appropriate positions as marked.

Ensure that the drill template position is vertical.
