Installation RRU-N
3.2.1 Unpacking and Checking the Material
Unpack the RRU-N on-site. To avoid damage, the RRU-N should not be
unpacked elsewhere and then transported to site.
In order to avoid damage to the components due to electrostatic discharges
during unpacking, personnel must not come in contact with the connectors of
the RRU-N.
Ensure that the correct material has been delivered. If the material is damaged,
complain the supervisor or the transport company immediately.
