EX600 Precautions Design/Selection Warning 1. Use this product within the specification range. Using beyond the specified specifications range can cause fire, malfunction, or damage to the system. Confirm the specifications when operating. 2. When using for an interlock circuit: . Provide a multiple interlock system which is operated by another system (such as mechanical protection function). . Perform an inspection to check that it is working properly. This may cause possible injury due to malfunction. Mounting Caution 1. When handling and assembling units: . Do not touch the sharp metal parts of the connector or plug. . Do not apply excessive force to the unit. The connecting portions of the unit are firmly joined with seals. . When joining units, take care not to get fingers caught between units. Injury can result. 2. Do not drop, bump, or apply excessive impact. Otherwise, the unit can become damaged, malfunction, or fail to function. 3. Observe the tightening torque range. Tightening outside of the allowable torque range will likely damage the product. IP67 protection class cannot be guaranteed if the screws are not tightened to the specified torque. 4. When lifting a large size manifold solenoid valve unit, take care to avoid causing stress to the valve connection joint. The connection parts of the unit may be damaged. Because the unit may be heavy, carrying and installation should be performed by more than one operator to avoid strain or injury. 5. When placing a manifold, mount it on a flat surface. Torsion in the whole manifold can lead to trouble such as air leakage or defective insulation. Wiring Caution 1. Confirm grounding to maintain the safety of the reduced wiring system and for anti-noise performance. Provide a specific grounding as close to the unit as possible to minimize the distance to grounding. 2. Avoid repeatedly bending or stretching the cable and applying a heavy object or force to it. Wiring applying repeated bending and tensile stress to the cable can break the circuit. 3. Avoid miswiring. If miswired, there is a danger of malfunction or damage to the reduced wiring system. 4. Do not wire while energizing the product. There is a danger of malfunction or damage to the reduced wiring system or input/output equipment. Caution 1. When it is UL compliant, use a class 2 power supply unit in accordance with UL1310 for a combined direct current power supply. 2. Use this product within the specified voltage range. Using beyond the specified voltage range is likely to cause the units and connecting devices to be damaged or to malfunction. 3. The power supply for the unit should be 0 V as the standard for both power supply for output as well as power supply for control/input. 4. Do not install a unit in a place where it can be used as a foothold. Applying any excessive load such as stepping on the unit by mistake or placing a foot on it, will cause it to break. 5. Keep the surrounding space free for maintenance. When designing a system, take into consideration the amount of free space needed for performing maintenance. 6. Do not remove the name plate. Improper maintenance or incorrect use of instruction manual can cause failure and malfunction. Also, there is a risk of losing conformity with safety standards. 7. Beware of inrush current when the power supply is turned on. Some connected loads can apply an initial charge current which will trigger the over current protection function, causing the unit to malfunction. 0 V Power supply for output Power supply for control/input +24 V +24 V 0 V Power supply for output Power supply for control/input .24 V +24 V Series VQC1000/2000 Specific Product Precautions 5 Be sure to read before handling.
