Cleaning of the SBU IO-Link in general
Depending on the environment, the SBU IO-Link may occasionally be exposed to a mixture of oil, dust and
other foreign particles. The operation and function of the SBU IO-Link can be negatively affected by these
deposits.
In order to avoid these malfunctions you must adhere to the maintenance intervals and clean the SBU IO-
Link from the outside at least every 6 months.
DANGER
Danger due to components moving in an uncontrolled manner.
Very serious injuries due to being crushed, pulled in, caught up or trapped as
well as due to abrasion, grazing and cutting.
The SBU IO-Link must be switched off and secured against being inadvertently
switched on again before any cleaning work.
Do not carry out cleaning during running operation.
CAUTION
Danger due to incorrect or aggressive cleaning agent.
Injuries or damage to the SBU IO-Link .
The safety data sheets for the cleaning agent must be available and observed.
Use only a dry cloth and if necessary a commercially available cleaning agent.
DANGER
Danger to life due to high voltage
Very serious injuries or death due to electrocution.
Fluid can penetrate into the switch box if spray water with too high a pressure is
used. People could come into contact with live parts.
Switch the SBU IO-Link off and secure it against being switched on again.
The SBU IO-Link may only be connected by an electrician.
Dust layers on the components of the SBU IO-Link could impair the exchange of heat with the ambient air.
This can lead to a build-up of heat. In order to avoid an impermissible temperature increase above the
maximum permissible surface temperature, any deposits or dust layers must be removed.
Dust layers are to be removed by vacuum cleaning before the layer thickness reaches 5 mm.
