Otherwise failure or malfunction can result. Insufficient supply voltage may not drive a load due to a voltage drop inside the product.
- Page 7 ●Product handling ∗Installation •Do not apply excessive stress to the product when it is panel mounted. Otherwise damage to the product and disconnection from the panel mount can result. •Ensure that the FG terminal is connected to ground when using a commercially available switch-mode power supply.
- Page 8 ∗Environment •Do not use the product in area that is exposed to corrosive gases, chemicals, sea water, water or steam. Otherwise failure or malfunction can result. •Do not use in a place where the product could be splashed by oil or chemicals. If the product is to be used in an environment containing oils or chemicals such as coolant or cleaning solvent, even for a short time, it may be adversely affected (damage, malfunction, or hardening of the lead wires).
- Page 9 ∗Adjustment and Operation •Connect load before turning on the power. Otherwise it can cause excess current causing instantaneous damage to the product. •Do not short-circuit the load. Although an error is displayed when the product load is short circuited, excess current may cause the damage to the product.
