Grid Connection Devices with a high output can influence the energy quality of the grid due to
their current consumption.
This may affect a number of device types in terms of:
- connection restrictions
-
criteria regarding maximum permissible grid impedance
*)
-
criteria regarding the minimum required short-circuit power
*)
*)
both at the interface with the public grid
See technical data
In this case, the operator or the person using the device should check whether or
not the device is allowed to be connected, where appropriate through discussion
with the power supply company.
IMPORTANT! Ensure secure grounding of the grid connection!
Personal Protec-
tion and Protec-
tion of Others You are exposed to numerous hazards while handling the device, for example:
- Flying sparks and pieces of hot metal
- Arc radiation that poses a risk of injury to the eyes and skin
- Hazardous electromagnetic fields that pose a risk of death for individuals
with pacemakers
- Electrical risks from grid current and welding current
- Increased noise exposure
- Harmful fumes and gases
Wear suitable protective clothing when dealing with the device. The protective
clothing must have the following properties:
- Flame resistant
- Insulating and dry
- Covering the entire body and in good condition with no damage
- Safety helmet
- Cuffless pants
Protective clothing involves the following:
- Protecting the face and eyes from UV radiation, heat, and flying sparks with a
face guard featuring a regulation-compliant filter.
- Wearing regulation-compliant protective goggles with side protection behind
the face guard.
- Wearing rigid, wet-insulating footwear.
- Protecting hands with appropriate gloves (featuring electrical insulation and
thermal protection).
- Wearing ear protection to reduce noise exposure and protect against injury.
Keep persons, especially children, away during the operation of the devices and
during the plasma surface treatment process. However, if persons are in the vi-
cinity:
- Instruct them about all hazards (blinding hazard due to arcs, risk of injury
from flying sparks, fumes hazardous to health, noise exposure, possible haz-
ard due to grid current or process current, etc.),
- Provide suitable protective equipment, or
- Construct suitable protective walls and curtains.
Data regarding
Noise Emission
Values The device produces a maximum noise level of <80 dB(A) (ref. 1pW) when idling
and in the cooling phase following operation in relation to the maximum permit-
ted operating point at standard loading in accordance with EN 60974-1.
