3) Precautions on Operation in Europe (EU member country)
(1) Installation condition
Be sure to observe the following installation conditions to operate our product safely.
Installation category: Category II
Pollution degree: Class 2
(2) Protection against electric shock
The product is designed to comply with class I, where only basic isolation is provided.
The power supply circuit, primary control circuit and secondary control circuit
(inputs/outputs of CN1, CN2 and CN3) are isolated from each other only with basic
isolation.
Provide the final assembly, in which ABSODEX is installed, with auxiliary isolation
complying with EN50178 and EN60664-1 so that the dangerous primary voltage circuit is
separated from the external low-voltage operation circuit.
Use CN1 exclusively for the dialog terminal. Do not connect it to a computer. Connect the
dialog terminal only when entering or changing data. Disconnect it in other cases.
(3) Environment
Operate our product in pollution degree class 2 or cleaner environment. To use it in
pollution class 3, install the driver in a control cabinet (IP54) where entry of water, oil,
carbon, metallic powder, dust and others is blocked.
(4) Power supply
Operate under conditions of installation category II. To achieve the purpose, use a
reinforced isolation transformer at the power supply input section and use varistor (TVS)
or the like to block 1500V or higher impulse voltages.
(5) Grounding
Be sure to ground the protective grounding terminal of the driver to avoid electric shock.
Even if an earth leakage breaker is used, be sure to ground the protective grounding
terminal of the driver to avoid electric shock.
Connect only one cable when connecting a grounding cable to the protective grounding
terminal. Do not tighten two or more cables at a single terminal.
