Maintenance
High voltage when the anti-condensation heating is operational
The anti-condensation heating system is used when the drive is switched off due to production
downtime or maintenance. For this reason, the heating is supplied with voltage from a
separate line supply. When the supply voltage for the anti-condensation heating is connected,
dangerous voltages are present in the cabinet unit, even with EMERGENCY OFF or when
the main switch is open.
This voltage can cause serious injury.
The five safety rules must be observed.
Hot anti-condensation heating surface
When the temperature control limit value is reached the anti-condensation heating is switched
on. Once activated, the anti-condensation heating can generate a great deal of heat. Contact
can result in serious injury, such as skin burns.
● Ensure that the anti-condensation heating cannot be touched.
● Ensure that the anti-condensation heating is switched off before carrying out any repair
Risk of falling
When climbing onto the cover of the anti-condensation heating there is a risk of injury.
Therefore, do not use the anti-condensation heating system to help you get to the top of the
cabinet.
NOTICE
Non-approved spare parts
Using non-approved spare parts can affect the function of the equipment and damage it. Third-
party spare parts and unapproved spare parts may not meet the requirements.
Therefore, only use spare parts that have been approved by the manufacturer.
