- Page 6 Caution ■Do not touch the terminals and connectors while the power is on. Otherwise electric shock, malfunction or damage to the product can result. ■Do not touch the piping or its connected parts when the fluid is at high temperature. It may lead to burnt.
- Page 7 ●Product handling Installation Tighten to the specified tightening torque. If the tightening torque is exceeded the mounting screws and brackets may damaged. If the tightening torque is insufficient, the product may be displaced and the mounting screws may come loose. (Refer to page "Mounting and Installation".) Ensure that the FG terminal is connected to ground when using a commercially available switch-mode...
- Page 8 Wiring Do not pull the lead wires. In particular, never lift a product equipped with fitting and piping by holding the lead wires. Otherwise damage to the internal parts can result, causing malfunction or disconnection of the connector. Avoid repeatedly bending or stretching the lead wire, or placing heavy loads on it. Repeated bending stress or tensile stress can cause damage to the sheath, or breakage of the wires.
- Page 9 Environment Do not use the product in an environment that is constantly exposed to the splash of water. 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 could be splashed. Otherwise damage to the product and malfunction can result.
- Page 10 Adjustment and Operation Connect load before turning on the power. Do not short-circuit the load. Although an error is displayed when the product load is short circuited, excess current may cause damage to the product. Do not press the setting buttons with a sharp pointed object. This may damage the setting buttons.

Page 16: Mounting And Installation
Mounting and Installation ■Installation Never mount the product in a location that will be used as a foothold. The rotation angle of the monitor is 270 , in steps of 90 . Rotating the display part with excessive force will damage the end stop. -
Page 17: Piping
■Piping Use the product within the specified operating pressure range and temperature range. Proof pressure is 1.5 MPa. Connect the piping to the fittings. Mount the product so that the fluid direction is the same as the arrow indicated on the product. Never mount the product upside down. - Page 18 ●Connecting the piping Ensure that the metal piping attachments are tightened to the required torque (refer to the table below). If the tightening torque is exceeded, the product can be broken. If the tightening torque is insufficient, the fittings may become loose. When connecting piping to the product, a spanner should be used on the metal piping attachment only.
