3) In order to improve noise resistance,
class 3 grounding of the control panel is
recommended.
4) Turn off the power before connecting/
disconnecting connector cables.
4. Operating environment
1) Use the product at ambient operating
temperature between 0 ° C and 55 ° C
and 131 °
2) The main unit is made of resin; there-
fore, do not use it in areas where it may
come in contact with (or be exposed to)
organic solvents such as benzine, thinner,
and alcohol or strong alkaline substances
such as ammonia and caustic soda.
3) Do not use the product in areas where
it may be exposed to flammable gases,
corrosive gases, excessive dust, or mois-
ture, or areas where it may be subjected
to strong vibration or shock.
5. Transporting and storage
1) If the product is subjected to extreme
vibration while being transported, the re-
lays may become detached, the lead may
become bent, and the unit may become
damaged. Handle the inner and outer
boxes with care.
2) If the product is stored in an extremely
adverse environment, visible defects and
deterioration of performance characteris-
tics may result. We recommend the fol-
lowing storage conditions.
• Temperature: 5 to 30 ° C
• Humidity: Max. 60% R.H.
• Environment: No hazardous sub-
stances such as sulfurous acid gases
and little dust.
