Read the health and safety warnings in chapter 1.2 Health and Safety Warnings.

1.  This unit contains dangerous voltages. Loss of life, severe personal injury or

property damage can be the result if the instructions contained in this manual are
not followed.

2.  It is compulsory to ground the unit before connecting power supply. A grounding

bolt is provided on the cabinet to connect the ground bonding cable.

3.  Although the remote unit is internally protected against overvoltage, it is strongly

recommended to earth the antenna cables close to the remote unit’s antenna
connectors for protection against atmospheric discharge. In areas with strong
lightning it is strongly recommended to insert additional lightning protection.

4.  If the mains connector of the remote unit is not easily accessible, a separation

device in the mains circuit must be provided within easy reach.

5.  Before connecting or disconnecting the mains connector at the remote unit,

ensure that mains supply is disconnected.

6.  Make sure that an appropriate circuit breaker and an overcurrent limiting device

are connected between mains and remote unit.

7.  A connection of mains supply to a power socket requires the power socket to be

nearby the remote unit.

8.  The remote unit might be supplied from IT mains. (The maximum nominal line to

line voltage must not exceed 400VAC).

9.  Incorrectly wired connections can destroy electrical and electronic components.

10. To avoid corrosion at the connectors caused by electrochemical processes, the

material of the cable connectors must not cause a higher potential difference than
0.6V (see electrochemical contact series).

11. It is sufficient to tighten the N antenna connector hand-screwed. Any use of a tool

(e.g. pair of pliers) might cause damage to the connector and thus lead to
malfunctioning of the remote unit.

12. For unstabilized electric networks which frequently generate spikes, it is advised

to use a voltage limiting device.

13. Observe the labels on the front panels before connecting or disconnecting any

cables.
