ELECTROSTATIC DISCHARGES
Electronic components are sensitive to electrostatic discharges.
Before performing any connection, operators shall make sure that they have discharged all
static electricity from their body before touching electronic components.
When the head unit is installed, it is possible to rotate its HMI in one of four different positions at 90°
intervals.
To rotate the HMI:
1 Make sure that the instrument is powered off and that the M4 hex head locking screws are screwed
in (see Figure 10).
2 Unscrew the housing cover on the HMI side (hazardous area warnings must be heeded; see "Safety"
on page 1).
CAUTION
Do not grab the instrument by its threaded interface. Thread edges are sharp and
constitute a risk of personal injury (see Figure 20 on page 29).
3 Pull the HMI board away from the communication board.
