4.1 Risk of electric shock
Danger to life due to electric shock
People can be seriously hurt or killed through physical contact with live
parts (e.g. 230 V~). Make sure that you cannot touch live lines during
installation. Disconnect devices from the mains power supply.
Please observe the accident prevention regulations and take all precautionary
measures to ensure the safe installation of the devices.
▪
Connection to power supply voltage and initial operation may only be carried out by qualified persons
trained in electrical engineering.
▪
The electrical installation, in which the device is to be operated, must comply with national standards.
To guarantee trouble-free operation, we recommend carrying out the electrical installation according
to the principles of a TN-S system, which means using separate neutral and grounding conductors.
▪
Secure the power cable with a strain relief, if necessary.
▪
The device must be connected via an all-pole separator to ensure that it can be disconnected
completely from the mains power supply, if required (service, maintenance).
▪
The device must be equipped with an external fuse protection with a maximum nominal current of
16 A.
4.2 Electrostatic discharge (ESD)
Electrical components and modules can be damaged by only slight, hardly
noticeable electrostatic discharge (ESD) without this becoming immediately
obvious. ESD damages result in malfunctions and even failure of the product.
Therefore, make sure that effective protective measures against electrostatic
discharge are in place when working on the open device.
Protective measures
Therefore, it is best to carry out maintenance work in an ESD-protected environment:
▪
ESD-compliant shoes, protective gloves and outerwear.
▪
ESD-compliant work surfaces with conductive mats as surfaces (if possible).
▪
ESD-compliant tools.
▪
ESD-compliant personal protective grounding, e.g. wrist grounding strap.
▪
Where this is not possible (e.g. product already installed), at least touch a grounded item in order to
conduct electrostatic charge away from your body.
