Special hazards during installation:
DInjury can be caused by the electrical current from live cable ends and
components.
DLines which are not laid properly (eg bending radius too small) can cause
scorching and electrical fires.
If the bending radius is too small, it should be removed.
DElectrostatic processes can cause damage to electronic components.
Attention!
Only touch the edge of the printed circuit board and avoid static
caused for example by clothing.
DBefore working on electrical installations or equipment (components,
housings, etc.), they are to be disconnected from the mains.
Any on/off or emergency stop switches are to be fitted with a lock to
immobilise them in the open position and a warning sign is to be put up.

6 Initial Commissioning
6.1 Safety instructions for initial commissioning
To prevent damage to property and/or life-threatening injury to personnel
always observe the following:
DBefore starting for the first time, check that all tools and other parts have
been removed from the danger area.
DActivate all safety devices and emergency stop switches before
commissioning.
DAre all of the operating media suitable, present and connected?
Also read the chapter on ”Safety”.
Special risks involved in initial commissioning:
DIncorrectly wired connections may destroy electrical/electronic
components.
DDefective connections can cause the product to start up unexpectedly or
make uncontrolled movements.
DElectrostatic processes/interference may endanger electronic components
and also lead to software faults and data loss. Back up data regularly
therefore.
Attention!
Only touch the edge of the printed circuit board and avoid static
caused for example by clothing.
6.2 First start
DVerify correct voltages (100-120V AC) at the input with a volt meter on AC
setting.
DVerify voltage at the output (24-27V AC) with a volt meter on AC setting.
DSwitch the wash signal on at the washer and verify voltage at the output
(12-18V AC) with a volt meter on AC setting.
6.3 Checks after initial commissioning
DVerify all screws are tight and electrical connections are secure.
