Mounting 1. Do not drop, bump, or apply excessive impact. Otherwise, the unit can become damaged, malfunction, or fail to function. 2. Hold the body while handling this product. 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. 4. Do not install a unit in a place where it can be used as a scaffold. Applying any excessive load such as stepping on the unit by mistake or placing a foot on it, will cause it to break. 5. Do not use in direct sunlight. Do not use in direct sunlight. It may cause malfunction or damage. 6. Do not use in places where there is radiated heat around it. Such a place is likely to cause malfunction. Caution Serial Wiring EX510 Precautions Wiring 1. Avoid miswiring. If miswired, there is a probability of damaging units or connecting devices. 2. Do not wire while energizing the product. It is likely to damage the units or connecting devices. 3. Avoid wiring the power line and high pressure line in parallel. Noise or surge produced by signal line resulting from the power line or high pressure line could cause a malfunction. Wiring of the reduced-wiring system and the power line or high pressure line should be separated from each other. 4. Confirm the wiring insulation. Inferior insulation (contact with other circuit, insulation between terminals, etc.) will likely cause damage to the units or connecting devices due to excessive voltage or the influx of current. 1. Take measures to avoid applying repeated bending force or pulling force to the cable. Also, pay attention not to place any heavy matter on the cable or clipping. It is likely to cause a broken wire. 2. Confirm grounding to maintain the safety of the reduced-wiring system and for anti-noise performance. Grounding should be close to units and keep the grounding distance short. Warning Caution Design and Selection Caution 1. Keep the surrounding space free for maintenace. When designing a system, take into consideration the amount of free space needed for performing maintenance. 2. Use the following UL approved products for DC power supply combinations. 1) Controlled voltage current circuit conforming to UL508 Circuit uses the secondary coil of an isolated transformer as the power supply, satisfying the following conditions. . Max. voltage (with no load): 30 Vrms (42.4 V peak) or less . Max. current: (1) 8 A or less (including shorts), and (2)When controlled by a circuit protector (fuse, etc.) with the following rating 2) A circuit (class 2 circuit) with maximum 30 Vrms (42.4 V peak) or less, and a power supply consisting of a class 2 power supply unit confirming to UL1310, or a class 2 transformer confirming to UL1585 3. This product is one of the components to be equipped into a final equipment. Confirm the adaptability to the EMC directive as the whole equipment by customers themselves. 4. The power supply for the Gateway unit should be 0 V as the standard for both power supply for outputs as well as inputs and for the control unit of the Gateway. +24 V 0 V +24 V Power supply for the input and for the control unit of the Gateway Power supply for output +24 V 0 V .24 V Power supply for the input and for the control unit of the Gateway Power supply for output No-load voltage (V peak) 0 to 20 [V] Over 20 [V] to 30 [V] Max. current rating 5.0 100 Peak voltage value Series VQZ Specific Product Precautions 6 Be sure to read before handling.
