Insufficient torque can cause displacement of the product from its proper position and the looseness of the mounting screws. •If a commercially available switching power supply is used, be sure to ground the frame ground (FG) terminal.
  • Page 9 Wiring (Including connecting/ disconnecting of the connectors) •Do not pull hard on the lead wire. Especially never lift the product equipped with fitting and piping by holding the lead wires. Damage to the connector, circuit board, cover or internal components may result, causing failure or malfunction. •Avoid repeatedly bending, stretching or applying a heavy object or force to the lead wire.
  • Page 10 Operating environment •Do not use the product in an environment where the product is constantly exposed to water splashes. Otherwise failure or malfunction can result. Take measures such as using a cover. •Do not use the product in an environment where corrosive gases or fluids can be splashed. Otherwise damage to the internal parts can result, causing malfunction.
  • Page 11 Adjustment and Operation •Connect the load before turning the power supply on. •Do not short-circuit the load. Although error is displayed when the product load has a short circuit, generated over current may lead to the damage of the product. •Do not press the setting buttons with a sharp pointed object.

Maximum updating time of accumulated value is 1.5 million times. If the product is energized for 24 hours per day, the product life will be as follows: •Data memorized every 5 minutes --- 5 minutes x 1.5 million times = 7.5 million minutes = 14.3 years •Data memorized every 2 minutes --- 2 minutes x 1.5 million times = 3 million minutes = 5.7 years...
