3.1.1 Precautions during installation
(1) Precautions when carrying the unit
The robot driver uses plastic parts. Handle it carefully to avoid damage to the plastic
parts.
Take special care not to carry the unit in such a way that force is applied only to the
front cover or terminal block cover. Otherwise you might drop the unit.
Do not install and operate the unit if any part is damaged or missing.
(2) Install the unit on an incombustible (metal) surface.
The robot driver becomes hot during operation. To prevent fire always install it on an
incombustible, straight vertical metal wall.
Also provide enough space around the unit. If there is any heat generating device
(braking resistor, electric reactor, etc.), keep the unit a sufficient distance away from
it.
Air flow
Robot driver
Provide enough space so that upper/lower
wiring ducts will not block cooling air flow.
Wall
(3) Ambient temperature precautions
The ambient temperature in the installation place should not exceed the allowable
operating temperature range (0 to 40˚C) specified in the standard specifications.
Measure the ambient temperature at a position about 50mm away from the lower
center of the robot driver body, and make sure that it is within the allowable operating
temperature range.
Operating the robot driver at a temperature exceeding the allowable range may
shorten its service life (especially, capacitor life) or damage the internal components.
(4) Do not install the unit in locations subject to high temperatures and high humidity
where condensation tends to occur.
Always operate the robot driver within the allowable operating humidity range (20 to
90% RH) specified in the standard specifications. In particular, operate it in locations
free from condensation.
If water droplets formed inside the robot driver due to condensation, this might cause
short-circuits between electronic components that result in malfunction.
Avoid installing the unit in locations exposed to direct sunlight.
(5) Installation environment precautions
Avoid installing the unit in locations subject to dust, corrosive gases, explosive gases,
combustible gases, grinding lubricant mist or salt damage. Dust or debris penetrating
the unit may cause malfunction.
If the unit must be used in very dusty place, house it in a sealed dust-proof box.
