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.
To prevent over-heating and fire, wire so that the
weight of the cable will not strain the connectors.
Do not expose the controller to water.
Water may damage the controller and cause an
electric shock.
Use specified wires with the proper current
carrying capacity to prevent current leakage,
over-heating, or fire.
Do not touch the PCB (Printed Circuit
Board) with your hand or a tool. Also do
not get dust on the PCB.
It may cause a fire or malfunction.
To reduce the risk of electric shock, install and
wire the unit with the power to power supply unit
turned off.
CAUTION
Do not install this controller where an acid,
alkaline solution, special chemical spray is
used frequently to avoid electric shock or
malfunction.
Do not press the switches with sharp objects.
It may cause an electric shock or malfunction.
To avoid causing damage or fire, do not apply an
AC voltage or a voltage higher than 30V DC to
the M-NET terminal blocks on the controller.
Do not touch the switches with wet hands.
It may cause an electric shock or 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.
