• Make sure you have a building plan showing common equipment, extensions, the telecom demarca-
tion, and earth ground location. The installation site must meet the following site / environmental
requirements.

1.1.4 Site Requirements

• The system without the IP4WW-Battery Box should be wall-mounted only. The system with the
IP4WW-Battery Box can be installed either on the floor or wall. Ensure that enough space is available
to allow the installation of KSU(s) and/or battery box.
• A dedicated 100V-120V/220V/230V/240VAC circuit located within 2 meters of the KSU is required. A
separate dedicated AC outlet is necessary for each KSU.

1.1.5 Environmental Requirements

Meeting established environmental standards maximizes the life of the system. Make sure that the site
is not:
• In direct sunlight or in hot, cold or humid places.
• In dusty areas or in areas where sulfuric gases are produced.
• In places where shocks or vibrations are frequent or strong.
• In places where water or other fluids comes in contact with the equipment.
• In areas near high-frequency machines or electric welders.
• Near computers, telexes, microwaves, air conditioners, etc.
• Near radio antennas (including shortwave).

1.2 Installing the Main KSU (1632M-A KSU)

The Main KSU has a CPU-A card, 4 trunks and 8 hybrid extension Interface with one power failure
transfer circuit, and control relay circuit for External device. And three mounting space for optional card
(408E-A1/008E-A1/000E-A1/1PRIU-C1) are available.
When the IP4[ ]-MEMDB-C1 is installed into the CPU card, Expansion KSU can be installed to
increase the capacity of the system. Each KSU (Main or Expansion) is powered by a power supply.
