Read the health and safety warnings in section 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.  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 over-voltage, it is 

strongly recommended to earth the antenna cables close to the antenna 
connectors of the Remote Unit for protection against atmospheric discharge. In 
areas with strong lightning it is highly recommended to insert additional lightning 
protection. 

4.  If the mains connector of the Remote Unit is not easily accessible, a disconnect 

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 over-current 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.  Incorrectly wired connections can destroy electrical and electronic components. 

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

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

10. Use an appropriate torque wrench for the coupling torque (25 N-m / 19 ft lb) of 7-

16 DIN connectors with 1-1/4 in opening to tighten the 7/16-type antenna 
connectors. For example, use torque wrench of item no. 244377 available from 
the  Andrew  e-catalog. Do NOT use your hands or any other tool (e.g. a pair of 
pliers)! This might cause damage to the connector and lead to a malfunction of 
the Remote Unit. 

11. Use a voltage limiting device for unstabilized electric networks that frequently 

generate spikes.  

12. The unit complies with the surge requirement according to EN 61000-4-5 (fine 

protection); however, it is recommended to install an additional medium (via local 
supply connection) and/or coarse protection (external surge protection), 
depending on the individual application, in order to avoid damage caused by 
overcurrent. 

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

cables.
