3.1 Driver
1) Precautions
When installing, please be sure to protect the following precautions.
■
Various precautions
The device should be installed on non-flammable surfaces only. Installation on or near flammable
materials can cause fire.
Do not stand, and put heavy items on the driver.
Operate the device within the specified environmental conditions.
Do not drop the device or subject it to excessive shock.
Make sure no screws or other conductive or flammable materials get inside the driver.
Do not obstruct the air intake and exhaust vents.
The attachment direction should be observed strictly.
Please contact our office if the driver is to be stored for a period of 3 years or longer. The capacity of the
electrolytic capacitors decreases during long-term storage.
Any damaged parts and parts with the mounting parts have been damaged shall be fixed by returning to
our company immediately.
■
If enclosed in a cabinet
The temperature inside the cabinet can exceed the external temperature depending on the power
consumption of the device and the size of the cabinet. Consider the cabinet size, cooling, and placement,
and make sure the temperature around the driver does not exceed 55[°C]. For longevity and reliability
purposes it is recommended to keep the temperature below 40[°C].
■
If there is a vibration source nearby
Protect the driver from vibration by installing it on a base with a shock absorber.
■
If there is a heat generator nearby
If the ambient temperature may increase due to convection or radiation, make sure the temperature near
the driver does not exceed 55[°C].
■
If corrosive gas is present
Long-term use may cause contact failure on the connectors and connecting parts.
Never use the device where it may be exposed to corrosive gas.
■
If explosive or combustible gas is present
Never use the device where explosive or combustible gas is present. The device’s relays and contacts,
regenerative resistors and other parts can arc (spark) and can cause fire or explosion.
■
If dust or oil mist is present
The device cannot be used where dust or oil mist is present. If dust or oil mist accumulates on the device,
it can cause insulation deterioration or leakage between the conductive parts, and damage the driver.
■
If a large noise source is present
If inductive noise enters the input signals or the power circuit, it can cause a malfunction. If there is a
possibility of noise, inspect the line wiring and take appropriate noise prevention measures. A noise
filter should be installed to protect the driver.
