2.3 Connection to the IC System
2.3.1 Electrical connection to the 732 IC Detector
In order to allow remote control via 732 IC Detector the 752 Pump Unit
must be connected to the "Remote" connection of the 732 IC Detector
with the 6.2143.200 cable as shown in Fig. 4. To allow the remote con-
trol to operate, switch 22 "REMOTE" on the front of the 752 Pump Unit
must be set to "ON".
If a second, additional instrument (e.g. 752, 753, 754) is to be con-
nected to the Remote interface of the 732 IC Detector then the
6.2143.220 cable (available as an option) should be used to connect
the 752 Pump Unit instead of the 6.2143.200 cable.

2.3.2 Connection of the suppressor module
The Metrohm Suppressor Module MSM built into the 2.733.0X30 IC
Separation Center is described in detail in section 2.8.3 of the 732/733
Manual. The 752 Pump Unit is used to supply regeneration and rinsing
solutions to the suppressor module. To avoid contamination of the
suppressor module by foreign particles or bacterial growth, it is advan-
tageous to install an in-line filter between the 752 Pump Unit and the
inlet capillaries of the suppressor module. The two 6.2821.100 Filter
units PEEK (see section 2.6.3 of the 732/733 Manual) supplied with
the 2.733.0X30 IC Separation Center are eminently suitable for this pur-
pose.
Connection of the suppressor module to the 752 Pump Unit is carried
out as described in section 2.8.6 of the 732/733 Manual. The most im-
portant points are repeated here; underlined numbers ## ## refer to op-
erating elements in the 732/733 Manual:
