8 Maintenance and repair
8.1 Cleaning and servicing
Danger! Electric voltage! Operations in the vi‐
cinity of live parts are extremely dangerous.
Any work required on the electric system may be carried out
only by skilled electricians. Tools for electricians (VDE tools)
are absolutely necessary.
Prior to commencing work:
1. Isolate (even auxiliary circuits).
2. Secure against reactivation.
3. Ensure de-energization.
4. Ground and short-circuit.
5. Cover or shield any adjacent live parts.
Personal and material damage during main‐
tenance work in operation!
Never do any maintenance work on life machines.
While carrying out maintenance work, secure the machine
such that it cannot restart or be used by unauthorized per‐
sons.
Hot surfaces with temperatures over 70 °C
may cause burns!
Before working, let the energy storage device cool down.
Wear safety gloves.
Do not work on hot surfaces.
Energy storage device
Excessive dirt, chips or dust can negatively influence the energy storage de‐
vice functions. In extreme cases lead to loss. Clean the cooling fins of the en‐
ergy storage device at regular intervals (after one year at the latest) to reach
a sufficiently high heat emission surface. If the cooling fins are partially cov‐
ered with dirt, sufficient heat dissipation via the ambient air is no longer en‐
sured.
Connection cable
Death by electrocution possible due to live
parts!
Immediately put the machine out of operation and replace
defective connection cables.
Never do any provisional repairs on the connection cables.
● Check in regular distances the connection cables on damage and re‐
place them if necessary.
● Check optionally existing drag chains Drag chains) on defects.
