Cabinet connections

Mains power

Wiring to the mains outlet inside the RTU must be installed by a suitably qualified person. Ensure the 4100ESi is
wired with a dedicated current limited mains supply, complying with the requirements outlined in AS/NZS
3000 Wiring Rules. To meet electrical safety requirements, ensure the outer sheath of the mains cable extends
into the mounting block of the mains outlet. The incoming earth wire connects to the earth terminal on the gear
plate.

RUI communications

Class A loop wiring is required for RUI communications wiring from the 4100ESi host panel to the RTU,
providing fault tolerance. The communications wiring is 1.5mm² shielded twisted pair cable. The maximum
distance around the loop is 1200m. RTUs are connected to the loop in any order.
See Figure 58. Ferrite bead wiring, for information about fitting the ferrite beads.

Commissioning

Set card addresses on the eight position DIP switch on the TIC, the APS/LPS, and any other cards in the RTU.
Match the address to the programmed address in the host 4100ESi panel.
To provide twenty four hour standby operation, connect two 12V batteries to the RTU as a backup to the LPS or
APS power supply. Battery leads are supplied with the RTU.
The LPS/APS monitors power supply faults, and fault signals pass to the host 4100ESi panel for indication. The
indicators on the LPS/APS give a basic go/no go indication of fault status.
The power supply does not require any adjustment during commissioning.

Adding PDI cards

Up to four additional standard PDI cards, two dual height PDI cards, two dual PDI brackets, or a combination of
these, fit in the unused PDI blocks in the 8U RTU cabinet.
Note:
In an 8U cabinet, a Dual PDI bracket mounted on the gearplate physically clashes with any LED
Switch controller, LED Pushbutton modules, or fan control modules fitted to a display door
directly in front of the bracket. Careful positioning is required.
