4.2.5 Electrical Installation

4.2.5.1 Electrical Safety Precautions

Please read the general Safety Precautions presented in Section 1.2 Safety Precautions

1. This Unit uses high voltages. Follow the instructions for installation provided in this

manual to prevent serious accidents including loss of life, severe personal injury or

extensive property damage.

2. The Unit must be grounded before connecting any power supply. Grounding is a

required precautionary measure. Grounding instructions are provided and should be

followed for safety.

3. The Unit is internally protected against over-voltage, but in areas with strong and frequent

lightning strikes additional lightning protection is strongly recommended. Grounding the

antenna cables close to the antenna connectors will help prevent damage from atmospheric

discharge.

4. Verify that there is a suitable circuit breaker and an over-current limiting device connected

between the mains and the Remote Unit.

5. Check that the mains supply is disconnected, before connecting or disconnecting the main

power connector at the Remote Unit.

6. An easily reached emergency disconnect device should be provided in the mains circuit if the

power feeds to the Remote Unit(s) are not within close reach.

7. The Remote Unit should be installed in close proximity to a power source with a circuit

breaker to ensure safe installation and for ease of power connectivity.

8. Electrical and electronic components can be destroyed by incorrectly wired connections.

9. Cable connector materials must meet manufacturer specifications to avoid corrosion at the

connectors.

10. Check cable connections to ensure that water cannot penetrate the Unit.

11. Caution should be used when attaching the antenna. Hand tightening should be sufficient for

connecting the antenna during installation. Manufacturer's recommendation for torque

specification should be used during installation. Use the appropriate tool to complete the

Antenna installation, but do not use tools, such as pliers, as they may cause damage to the

Remote Unit.

12. A voltage limiting device is strongly recommended for electrical networks that often produce

spikes.

13. Compliance with the surge requirement of EN 61000-4-5 (fine protection) has been met by this

Unit. Installing additional external surge protection, depending on the individual application,

via local supply connection and/or coarse protection is recommended to avoid damage

caused by electrical surges.
