4 Installation guidelines

Only qualified electricians are allowed to carry out what described in this
chapter. Please operate as the instructions in chapter 1 Safety precautions.
Ignoring these may cause physical injury or death or damage to the devices.

Ensure the power supply of the RBU is disconnected during the operation.
Wait for at least the time designated until the POWER indicator is off after the
disconnection if the power supply is applied. It is recommended to use the
multimeter to monitor that the DC bus voltage of the drive is under 36V.

The installation and design of the RBU should be complied with the
requirement of the local laws and regulations in the installation site. If the
installation infringes the requirement, our company will exempt from any
responsibility. Additionally, if users do not comply with the suggestion, some
damage beyond the assured maintenance range may occur.

Don not hold the front cover only during moving, otherwise the machine may
fall.
4.1 Installation environment
The installation environment is the safeguard for a full performance and long-term working of the RBU.
Check the installation environment as followings:
Environment Conditions

Environment
temperature
-10
–+40°C
It is not recommended to use the RBU if the ambient temperature is
above 40°C.
In order to improve the reliability of the device, do not use the RBU
if the ambient temperature changes frequently.
Please provide cooling fan or air conditioner to control the internal
ambient temperature below the required one if the RBU is used in a
closed space such as in the control cabinet.
When the temperature is too low, if the RBU needs to restart to run
after a long stop, it is necessary to provide an external heating
device to increase the internal temperature, otherwise damage to
the devices may occur.
Humidity
RH≤90%
No condensation is allowed.
The maximum relative humility should be equal to or less than 60%
in corrosive air.
