Observe Safety Informations 0.2.
Disconnect and connect the cable connections only while the pump is
turning no longer (green status LED off) and with the mains power
switched off (yellow power LED off). Other wise there is the risk of damag-

The interface connectors have UNC 4-40 threads. Do not use connectors
with M3 treads.
The pump may be operated only with suitable connector cables.
Route all cables so, as to protect them from damage.
Plug in the mains cable. Refer to Fig. 3.12 for the mains plug connection.
In order to comply with the standard SEMI S2, install an additional mains

capacity of this mains power circuit breaker needs to be rated at 10,000 A
minimum.
