■Installation

Danger

		- Do not install or operate the inverter if it is damaged or any part is missing from it.
		Operating the inverter in a defective condition could lead to a shock or a fire.
	Prohibited	Request your Toshiba dealer for repair.
	Prohibited
		- Install the inverter on a non-combustible board, such as a steel plate. Installing it
		on an inflammable wall or board could lead to a fire because its back is heated up
		during operation.
	Mandatory	- Do not use the inverter with the front cover detached, or it could cause a shock.
	Mandatory	- Install an emergency shutdown device which matches the system (for example, a

		switch interlocked with the brake of the machine). Failure to do so could lead to
		injury to persons since it has no emergency stop function.
		- Do not use any optional devices other than those designated by Toshiba. The use
		of improper devices could lead to accidents.

		Warning

Prohibited

-Install the main unit on a wall, or the like, which is strong enough to withstand its weight, or it could fall and cause injury to persons.

-Install a mechanical brake whenever the motor requires a brake (device which retains the motor shaft). Failure to do so could lead to injury to persons because the inverter itself has no function of mechanically retaining the brake shaft.

■Installation place

Install the inverter vertically on a flat steel wall in a well-ventilated place. When installing two or more inverters, leave a clearance of at least 10 cm between inverters placed side by side.

above 5cm

above 10cm

above 5cm

above 10cm

The clearances indicated above are minimum clearances to be secured. Every air-cooling type model is equipped with a cooling fan. For this type of inverter, therefore, leave as large clearances as possible above and under the inverter.

For a model designed for 37kW motors or larger, leave a clearance of at least 20 cm above and under it for easy installation of wires and possible replacement of the fan.

Note) Do not install the inverter in a hot, damp, or dusty place, or a place full of metal chips. When you intend to install in a critical environment, consult your Toshiba dealer in advance.
