Make sure the output voltage is set to +26VDC +/- 0.1, or adjust if necessary, using a flat
head screwdriver.
Note:
The Live and Neutral of the AC mains supply conductors should be fitted with crimp-on boot-
lace ferrules and inserted into the DIN rail mains connectors 1 and 2 as shown in
Figure 6
.
The Ground / Earth conductor must be fitted with a crimp-on M6 ring terminal and secured
to the earth stud underneath the supplied M6 flat washer and nut on the OPT chassis.
The DIN rail main connector 3 should NOT be used; It is present for test purposes only.

Forecourt Connections
The TT8900 OPT comes standard with support for two PEC/NZ pump
communication channels (loops). It can also be optionally fitted with
support for one Gilbarco pump communication channel and/or one Email
pump communication channel.
Alternatively, the OPT can be optionally fitted with a Postec FCC interface
which is an RS232 standard interface. In this case no pump communication
channels are required as the forecourt pump network is connected to the
Postec FCC not the OPT.
All pump communication or RS232 wiring is terminated into the DIN rail
mounted SL protection devices located on the centre of the front DIN rail.
The number and type of SL protection devices fitted to the centre of the
front DIN rail in a particular OPT, and therefore the arrangement of them
on the DIN rail, will depend on whether the following options are included:
