Remarks to ambient conditions
The specified permissible ambient temperatures apply to operation of the turbopump at
maximum permissible fore-vacuum pressure or at maximum gas throughput depending
on the cooling method. The turbopump is intrinsically safe by a redundant temperature
monitoring.
●
By reducing the fore-vacuum pressure or gas throughput, the turbopump can be op-
erated at higher ambient temperatures.
●
If the maximum permissible operating temperature of the turbopump is exceeded, the
electronic drive unit reduces drive power first and switches off then, if necessary.

NOTICE
Contact load of accessory connections
The total contact load on the free accessory connections A1, B1 and B2 on the TCP
1200 connection panel must not exceed
250 mA
.
Connected devices must adhere to single load Imax = 200 mA.
RS-485
M12 socket with screw coupling. Occupied for the connection of the built-in display
and control unit
DCU 002
. Available for the connection of other devices via RS-485,
e.g. PC. The use of a Y-connector enables the series connection in a bus system.
accessory A
M12 socket with screw interlocking. Assigning for connecting internal accessories.
Accessory A1 is available directly on the pump via the "pump.2 output" control con-
nection. Accessory A2 is assigned for internal air cooling.
accessory B
M12 socket with screw coupling for the connection of Pfeiffer Vacuum accessories.
The use of a Y-connector enables double assignment of the connection.
PV.can
M12 casing socket with screw coupling and LED for the connection of an integrated
pressure measurement and for Pfeiffer Vacuum Service purposes.
remote
High Density D-sub 26 pole female socket for the connection and configuration of
a remote control.
