Connecting The Lan Cable; Making The Initial Settings; Test Run - Mitsubishi Electric BAC-HD150 Installation Manual

4-4. Connecting the LAN cable

• Make sure that the LAN cable is long enough to reach the LAN1 connector on the BAC-HD150. Leave the LAN cable
disconnected until all the initial settings for the BAC-HD150 (IP address setting etc.) have been completed.
• Connect the BAC-HD150 (LAN1) and the building management system via a HUB.
• The maximum distance between the HUB and BAC-HD150 is 100 m (328 ft).
CAUTION • Install the LAN cable before installing the unit, and route the cable in the same way as the M-NET transmission
lines.
• Connect the BAC-HD150 to a private network. Use a security device such as a VPN router when connecting to
the Internet. (Without a proper security measure in place, the air conditioning system is vulnerable to access
from unauthorized users.)

5 Making the initial settings

Note
Refer to the BAC-HD150 Instructions Manual and the Setting Tool Instructions Manual for how to make the initial
settings for the BAC-HD150.
1. Turning on the power
Disconnect the LAN cable for connection to the BACnet before turning the power on for the first time.
There is a possibility that the IP address of the unit is already used by another device that is connected to the BACnet.
2. Initial settings
Make the initial setting using the Setting Tool after turning on the power to the BAC-HD150.
Some of the items that require initial settings include BAC-HD150 address and air conditioning system related items.
• IP address of BAC-HD150 (The factory setting for LAN1 is "192.168.1.254.")
• M-NET address of BAC-HD150 (The factory setting is "0.")
• Group configuration for the air conditioning system
Refer to the BAC-HD150 Instructions Manual and the Setting Tool Instructions Manual for detailed instructions for how to make
the initial settings.
