3. INSTALLATION 3.1 Handling
During transportation, handle the brake unit and resistor unit carefully to protect them from damage. When holding the brake unit and resistor unit, do not apply force only to their front covers.
3.2 Place of Installation
(1) Do not install the brake unit and resistor unit where they are subjected to di-
rectsunlight,hightemperature,highhumidity,oilmist,flammablegases, fluff,dust,dirt,etc.Installtheunitinacleanplace or insideatotallyenclosed panel which does not accept any suspended matter. Note: When the brake unit or resistor unit is installed in a panel, the cooling method and panel dimensions should be determined so that the ambient temperature of the unit is within the permissible range (as specified on page 4). Extreme care should be taken when two or more brake units or resistor units are installed in the same panel or when a ventilation fan is mounted in the panel. If the units and/or ventilation fan is installed in an improper position, the ambient temperature of the units will rise and ventilation effect will reduce.

3.3 Installation Direction and Clearances
(1) Install the brake unit and resistor unit on an even surface securely and verti-
cally (so that the letters FR-BU of the brake unit and FR-BR of the resistor unit are situated at the front) with screws or bolts. (2) Leave sufficient clearance around the brake unit and resistor unit for adequate heat dissipation. (3) If they are repeatedly operated, the rear surface temperature of the brake unit and resistor unit may rise (up to about 150°C),so install the units on incombustible backplate (such as metal and earth the backplate).
