INSTALLATION

• 

The brake unit consists of precision mechanical and electronic parts. Never

install or handle it in any of the following conditions as doing so could cause
an operation fault or failure.

CAUTION

Mount the brake unit and resistor unit to incombustible material.
Installing it to combustible materials directly or near combustible
materials can cause a fire.

Direct sunlight

Vibration

(5.9m/s

2

 or more)

High temperature, 
high humidity

Oil mist, 
flammable gas, 
corrosive gas, 
fluff, dust, etc.

Horizontal 
placement

Vertical mounting
(when mounting 
inside an enclosure)

Mounting to 
combustible 
material

Transportation by 
holding the front 
cover
