UNIT INSTALLATION
1 Make connections from BAG to mainboard controller.
SQMB (with RS-485):
Make connections from TB_MB (BMS Gateway) to TB_WIR (SQMB) accordingly (A to A,
B to B, +5V to +5V, GND to GND).
* Note that +12V on BAG to be connected to HP1 at position shown in the
figure below:
Other mainboard controllers (without RS-485):
Plug in the provided 5-way harness wires to the connector, CN_MB on BAG and plug
the other end of the wire to CN_WIR on mainboard controller.
2 Make connections from BAG to wired panel.
SQLCD (with RS-485):
Make connections from TB_WIR (BAG) to TB (SQLCD) accordingly (A to A, B to B,
+5V to +5V, GND to GND).
SLM8 (BRC51A)/ SQSLM8 (BRC51A64)/ SLM9/ SQSLM9:
Plug in the wire harness provided in SLM8 (BRC51A)/ SQSLM8 (BRC51A64)/ SLM9/
SQSLM9 package to CN_MB on wired panel and connects the other end of the wire to
the connector (CN_WIR) on BAG.

5 Make connections from resistance input terminal block to BMS system as shown
below:
6 Adjust and align all wires to wire clips as shown in the image shown below:
7 Decide the location to install the BAG.
Please consider the following precautions in your decision:
Do not install the unit in location that is:
• Exposed to direct sunlight.
• Susceptible to humidity and moisture.
• Near to heat source.
• Near to machines that emits high frequency wave.
• Near to high current switching devices.
Caution:
• Over-tightening the screws can cause deformation or/and crack at the casing.
• Mount the bottom casing on a wall with flat surface. Unit mounted on an uneven surface
can cause cracks at the casing.

BAG interfaces the air conditioner unit to BMS system via input contacts, dry contacts
outputs and resistance input allowing monitoring and controlling of operating
parameters.
Resistance Input allows BMS system to control the set temperature of the air
conditioner unit according to resistance table below:
