Table 9.2 Display unit Ethernet connections
Connection Symbol Type Name
1 RJ45 DEIF network Ethernet connection to controller (default connection)
2 RJ45 Ethernet for additional display units
CAUTION
The display unit must be paired to a controller in the DEIF network. During commissioning, or the first time a display unit is
powered, the display unit prompts for a controller confirmation.
MORE INFORMATION
See the Commissioning guidelines for more information regarding the first pair selection.
9.1.2 Frame ground wiring
Connect the frame ground terminal to ground/earth.
CAUTION
The frame ground is connected to the power supply terminals through transient voltage suppression diodes (commonly
known as transorbs). In order to protect the frame ground and power supply, no more than 36 V is allowed between the
frame ground terminal and the power supply terminals.
9.1.3 Power supply wiring
Connect the power supply (+) to the 12 or 24 V DC power supply.
Connect the power supply (-) to the 0 V DC power supply.
CAUTION
Do not wire the negative power supply terminal of the modules with independent power supplies (for example, PSM 3.1) to
the ship single-phase ground. If the voltage between the power supply terminals and frame ground exceeds 36 V, then the
power supply terminals and the frame ground terminal will be damaged.
