Precautions For Safe Use - Omron ZW-7000 Series User Manual

Please observe the following precautions for safe use of the products.
1. Installation Environment
• Do not use the product in environments where it can be exposed to inflammable/explosive gas.
• To secure the safety of operation and maintenance, do not install the product close to high-voltage devices
and power devices.
• For adequate intake and/or exhaust, keep the Sensor Controller clear by 30 mm or more on its top, and by 10
mm or more from either side.
To secure the Sensor Head and cables connected safely, keep the front of the Sensor Controller clear by 65
mm or more.
• Always hook the upper edge of the slot on the Sensor Controller's back first onto the DIN track. After
completely installing the Sensor Controller, make sure that it is securely fixed.
• When mounting the Sensor Controller using the screws, make sure the screw is tightened with a torque
specified in this manual.
• Do everything possible to avoid installation in a location with vibration.
• Do not install the product near any devices that generate noise. If there is no choice but to install the product
in a noisy environment, make sure to take noise prevention measures.
2. Power Supply and Wiring
• Take care when using a power supply with an overcurrent detector, because this sensor uses DC-DC
converter for its power supply circuit and inrush current may activate the protective circuit for a power supply
with an overcurrent detector.
Recommended power supply: S8VS-06024 (Omron, DC24 V 2.5 A 60 W)
• The supply voltage must be within the rated range (DC24 V ± 10 %).
• Reverse connection of the power supply is not allowed.
• Unstable voltage may cause unexpected operation of the sensor controller. If such condition is anticipated,
use an UPS (Uninterruptible Power Supply).
Recommended UPS: S8BA Series (OMRON)
• Open-collector outputs should not be short-circuited.
• Use the power supply within the rated load.
• High-voltage lines and power lines must be wired separately from this product. Wiring them together or
placing them in the same duct may cause induction, resulting in malfunction or damage.
• Use adequate safety measures, for example fail-safe circuits.
• Use a specified-sized wire when wiring. Do not connect wires other than those of the specification to the
terminal block.
• Do not connect a wire with an only twisted end directly to a terminal block.
• For a power supply, use a DC power supply unit provided with a remedy, for example, safety ultralow voltage
circuit, to prevent a high voltage from being generated.
• Route so that power supply wires are as short as possible.
• Use a power supply dedicated for this product, without sharing it with other products.
• Before performing any of the following activities, be sure to turn off the product, or breakdown may result.
- Connecting or wiring cables
- Connecting or disconnecting connectors
- Installing or removing Calibration ROM
• Do not apply any loads to cables and connectors when wiring.
• When inserting or removing an EtherCAT cable, do not put any stress on the calibration ROM.
• Before turning ON the power after the product is connected, make sure that the power supply voltage is
correct, there are no incorrect connections (e.g. load short-circuit) and the load current is appropriate.
Incorrect wiring may result in breakdown of the product.
