2. 1. 2 How to install
Select an indoor location with good ventilation, and then install the inverter upright on a flat metal plate.
For the positions and sizes of the mounting holes, refer to [12. 2].
■ If multiple inverters are installed
To install multiple inverters in one location, either normal basic installation or side-by-side installation
(to align inverters side-by-side horizontally with no space) can be adopted.
WARNING
Prohibited
• Do not install and operate the inverter if it is damaged or any of its components is missing.
This will result in electric shock or fire. Please call your Toshiba distributor for repairs.
Mandatory
action
• Mount the inverter on a metal plate.
The rear panel will get high temperature. Do not mount the inverter on an inflammable object,
this will result in fire.
• Do not operate the inverter with the front cover removed.
The unit contains high voltage parts and contact with them will result in electric shock.
• An emergency stop device must be installed that is configured in accordance with the system
specifications.
If such an emergency stop device that can activate mechanical brake by shutting off power
supply is not installed, operation cannot be stopped immediately by the inverter alone, thus
resulting in an accident or injury.
• All options to be used must be those specified by Toshiba.
The use of options other than those specified by Toshiba will result in an accident.
CAUTION
Prohibited
• For transporting or carrying the inverter, do not hold by the front cover.
The cover will come off and the unit will drop, resulting in injury.
Mandatory
action
• Carry the inverter by two people or more when the inverter is the model mass 20kg or more
(VFAS3-2110P - 2370P, VFAS3-4220PC - 4750PC).
If you carry the inverter alone, this will result in injury.
• Install the inverter at a place which can support the unit's mass.
If you install the inverter at a place which does not support the unit's mass, the unit will fall,
resulting in injury.
• Install the mechanical brake when it is necessary to hold a motor shaft.
A brake function of the inverter cannot perform mechanical hold, and it results in injury.
