*6
*1: The reference temperature measurement position is 50mm below the bottom of the base unit.
*2: For long-term storage, store spare parts in dark places and avoid hot or wet places.
For long-term storage, the temperature and humidity should be 0° - 40°C and 20-80 %RH (no
condensation) respectively, and the temperature variation rate should be 10°C/h or less.
Particularly, high ambient temperatures affect the estimated usable periods of batteries and power
supplies. Store them at room temperature (25°C or less).
*3: The following components shall not be contained:
Hydrogen sulfide, sulfurous acid gas, chlorine gas, nitrogen oxides (NOx), sulfur oxides (SOx), ammonia,
silicon gas, etc.
*4: 5 ≤ f < 8.4Hz: Half amplitude 3.5mm, 8.4 ≤ f < 150Hz: Constant acceleration 9.8m/sec
2
*5: Grounding other than Class D grounding (e.g., mesh grounding) can be used for the system, provided
that the equivalent effect as with Class D grounding can be achieved. For grounding other than Class D,
the user needs to confirm the effect of the grounding.
*6: The “target durable years” in the general specification indicates the "design life" (target value), which is
not a guaranteed value.
The chance failure period of a product is generally referred to as durable years or service life. A
component which stops functioning before the design life of the product due to secular change or heavy
use is referred to as the limited-life part. Aluminum electrolytic capacitor, relays, fuses and
photo-couplers are classified to these parts in BUM7B.
The whole unit of BUM7B should be replaced, since it contains the limited-life aluminum electrolytic
capacitor at an average operating ambient temperature of 40°C and in standard installation condition
(natural cooling). The recommended replacing interval is 10 years.
In addition, the whole unit of module should be replaced if it contains the aluminum electrolytic capacitor.
The recommended replacing interval is 10 years.
