Chapter 4 Installing the HA-655 driver
4-3Location and installation
4-3-1Environment of location
The environmental conditions of the location are as follows:
Service temperature: 0 to 50
Use the driver in a cabinet. The temperature in the cabinet may be higher than the
atmosphere because of power loss of the housed devices and its size. Plan the cabinet
size, ventilation system, and device locations so the ambient temperature of the driver,
which is always less than 50.
Service humidity: less than 95% relative humidity, without condensation
Make sure that water condensation does not occur due to fluctuating temperatures in
the storage area or because of frequent heat-and-cool (run-and-stop) operations.
Vibration:
Impact:
less than 4.9m/sec 2 0.5G(10Hz to 55Hz)
When there is a great deal of vibration near the driver, attach a shock absorber under
the base to dampen the vibration.
less than 98m/s 2 (10G)
Make sure that dust, water condensation, metal powder, corrosive gas, water, water drops, or oil mist
is not exposed to the HA -655 driver.
Do not install the driver in a corrosive gas environment, because the gas may cause
damage to connecting parts (connectors, etc.).
Install the driver in a cabinet. Do not expose it to the sunlight.
4-3-2Notices on installation
Install the driver vertically and allow for wide spaces for air to flow sufficiently.
Leave 30mm or more from walls, 50mm or more from floor and 100mm from ceiling, and adjacent
devices as shown the figure below.
When planning the ventilation system for the cabinet refer to the table below, which lists the power
consumption of the HA-655 driver.
