Huawei RRU3971 - Hoisting an RRU and Related Cables onto a Tower

NOTICE
If an RRU is installed on the bitumen ground, the RRU must be at least 500 mm (700 mm or
more as recommended) away from the bitumen ground. The following describes the space
requirements for installing multiple RRUs on the non-bitumen ground.
NOTE
l The recommended clearances ensure normal running and provide appropriate space for operation and
maintenance (O&M). If the installation space is sufficient, leave the recommended clearances after
installing the equipment.
l The minimum clearance ensures normal running and heat dissipation, but O&M activities such as
checking indicator status and opening the cabling cavity cannot be properly conducted. If the
installation space is restricted, leave the minimum clearance after installing the equipment.
