3.3 Connections

3.3.2. HHL

The HHL housing and CTLm cable shown in ﬁgure 3.7 must be connected according

to the numbering of the CTLm connector pins (from 1 to 10) and the HHL connector

pins description provided in section 3.3.6. If you use a TC-3 temperature controller,

you should use the TC-HHL cable instead, with an identical connector on the HHL

side.

Figure 3.7.: HHL housing and CTLm cable.
