Temperature and Humidity Inspection
ZXSDR R8860 temperature and humidity in work environment should meet the
requirements, as shown in
Power Supply Inspection
The requirements of ZXSDR R8860 power supply are described as follows.
1. DC power supply: ZXSDR R8860 is –48 V DC power supply and the voltage of power
supply is –40 V DC~–57 V DC.
2. Indirect AC power supply: adopt an outdoor AC unit (OAU); the OAU can provide 220V
AC power supply for one ZXSDR B8200 C100 and one ZXSDR R8860 at the same
time.
Lightning Inspection
The ZXSDR R8860 lightning requirements are described as follows.
l
Outdoor Installation
1. For DC power supply, configure an outdoor DC lightning box OLP48-2. If the
DC power is exported from the equipment room, the length of power cable is
more than 10 m (less than 50 m) and the output end of indoor DC power is not
configured with B-level or above lightning devices, it is required to configure an
indoor DC lightning box ILP48–3 in the equipment room.
2. For indirect AC power supply, it is required to configure an AC lightning box
(ZXPCS combined arrester).
l
For indoor installation, if the power cable is distributed outdoors, configure the power
lightning box according to the conditions of outdoor installation.
Grounding Inspection
ZXSDR R8860 adopts an associated grounding mode. The value of grounding resistance
is not more than 5 ohm.
Other Inspections
1. The corollary devices or components should accord with the requirements of ZXSDR
R8860 engineering design drawing.
2. The transmission devices interconnected with BBU should have been prepared.
