CAUTION
IMPORTANT
Do not install the controller where there is a
risk of leaking flammable gas.
If the leaked gas accumulates around the
controller, it may ignite and cause an explosion.
Do not use the controller in an environment
high in oil, steam, or sulfuric gas.
These substances may have adverse effects on
the performance of the controller or damage its
parts.
Do not wash the unit with water.
Doing so may cause an electric shock or
malfunction.
Do not install this controller where an acid or
alkaline solution or special chemical spray is
used frequently to avoid electric shock or
malfunction.
Do not spray insect sprays or sprays with
flammable propellants to the controller.
To avoid the risk of fire or explosion, do not place
flammable sprays near the controller or spray
them directly on the controller.
Do not use the controller for specialized
applications.
This product is designed exclusively for use with
the MITSUBISHI ELECTRIC building air
conditioning control system. The use of this
product with other air-conditioning management
systems or for other purposes may result in
malfunctions.
To reduce the risk of electric shock, install and
wire the unit with the power to the
PAC-SC50/51KUA power supply unit turned
off.
When installing the controller in a hospital or
communication facility, take appropriate
measures to reduce electrical noise
interference.
Inverter equipment, generators, high-frequency
medical equipment, or radio communication
equipment may interfere with the normal
operation of the controller; or the electrical noise
from the controller may interfere with the medical
practice or cause image distortion and static.
Operate the controller within the temperature
range specification.
The use of controller outside of its specification
may result in serious damage to the controller. Be
sure to check the temperature range specification
in the Instruction Book.
Do not install this controller in a place that
has the potential for steam or dew formation.
Steam or dew formation may cause an electric
shock or a unit malfunction.
Use a security device such as a VPN router
when connecting the GB-24A to the Internet
to prevent unauthorized access.
If no security devices are installed, the operation
settings may be changed by an unauthorized
person without the knowledge of the user.
Do not touch the PCB (Printed Circuit Board)
with your hand or a tool.
Keep the PCB dust-free to prevent fire or
malfunction.
Enable the “Automatic restoration after power failure” function on the air conditioning units.
Otherwise, the hold function will prohibit the schedule from being executed, and the units will remain
stopped even after power is restored. Enable this function for the units to automatically resume their
o
eration after
ower is restored.
