3.1.3 Handling the MU
Do not lift the MU by the splice cassette box because the cassette or the cassette
box may break.
Take care not to damage the door switch of the MU when lifting the MU.
3.1.4 Installation of the MU, CPSU and the RUs
Installation of the MU and CPSU above a height of 2 meters is not recommended
due to the difficulties of installing and maintaining the units above this height.
Personnel who are installing the MU, CPSU and the RUs should be informed
about the possible risks and safety measures when elevated. The use of an air
platform for installations of RUs at height is recommended.
3.1.5 Grounding
The MU may receive damaging overvoltages through the RF jumper cable from
the BTS or via power supply lines.
Sufficient protective grounding is required. A current power plug with ground
connection is not sufficient: the grounding of the MU must be based on a fixed
grounding cable.
3.1.6 Electrostatic discharge protection
Always wear a close-fitting antistatic wrist strap around your uncovered wrist
when handling the plug-in units of the MU!
