■NOTE
○Follow the instructions given below when designing, selecting and handling the product.
●The instructions on design and selection (installation, wiring, environment, adjustment, operation,
maintenance, etc.) described below must also be followed.
∗Product specifications
•The direct current power supply to combine should be UL approved as follows.
Circuit (of class 2) which is of maximum 30Vrms (42.4 V peak) or less, with UL 1310 class 2 power supply unit or UL
1585 class 2 transformer.
The Flow monitor is a UL approved product only if it has a UL mark on the body.
•
Use the specified voltage.
Otherwise failure or malfunction can result.
Insufficient supply voltage may not drive a load due to a voltage drop inside the product.
Verify the operating voltage of the load before use.
•
Do not exceed the specified maximum allowable load.
Otherwise it can cause damage or shorten the lifetime of the product.
•
Design the product to prevent reverse current when the circuit is opened or the product is forced to operate for
operational check.
Reverse current can cause malfunction or damage to the product.
•
Input data to the product is not deleted, even if the power supply is cut off.
(Writing time: 1000000 times, Data duration: 20 years after power off.)
•
Reserve a space for maintenance.
Allow sufficient space for maintenance when designing the system.
∗Installation
•Tighten to the specified tightening torque.
If the tightening torque is exceeded the mounting screws and brackets may be broken.
If the tightening torque is insufficient, the product can be displaced and loosen the mounting screws.
(Refer to "Mounting and Installation" on page 15 to 16.)
•
Do not apply excessive stress to the product when it is mounted with a panel mount.
Otherwise damage to the product and disconnection from the panel mount can result.
•Be sure to ground terminal FG when using a commercially available switch-mode power supply.
•Do not drop, hit or apply excessive shock (over 100 m/s
Otherwise damage to the internal parts can result, causing malfunction.
•Do not pull the lead wire forcefully, not lift the product by pulling the lead wire.
Hold the body when handling to avoid the damage of the product which lead to cause the failure and malfunction.
•Never mount a product in a location that will be used as a foothold.
The product may be damaged if excessive force is applied by stepping or climbing onto it.
