The enclosure is mounted on a wall using four mounting feet, Figure 2.20. Do not drill mounting holes in
the enclosure.
Note: The LCD display has an operating temperature range of 0...50°C and a storage temperature range of
-20...60°C.
Check the serial number from the label, Figure 2.11.
An Indicating transmitter can be exchanged for another of the same model, but the current calibration
constants have then to be entered by the keyboard (Section 5.7). For compatibility information, see Section
2.9.
3.6. ELECTRICAL CONNECTIONS
The electric terminals of the Indicating transmitters are all on the Power Supply card, Figure 6.40. This is
accessible by opening the enclosure and the front panel. The front panel swings out after the two screws to
the right have been loosened (Section 7,3, item 3.14). For intrinsically safe connections, see Section 12.2.
Power:
The power is specified in the DELIVERY DATA SHEET and on the Label (Figure 2.11). The position of
the power select switch on the Power Supply card (SW2 in Figure 6.40) should also be checked. The
power selection switch has two positions: 220-240 V/50-60 Hz or 100-115 V/50-60 Hz.
The primary AC power is connected to a separate terminal strip 39/40/41 on the Power Supply card
marked POWER (Figure 6.40): The terminals are marked 39/L, 40/N and 41/ground symbol.
The power terminals L and N are directly connected to the transformer primary loop, and galvanically
separated from the rest of the instrument. The ground terminal (41) is connected to the bottom plate of the
Indicating transmitter, to the transformer shield winding and to the outer shield of the interconnecting
cable.
Power for +24V DC Indicating Transmitters:
The power is specified in the DELIVERY DATA SHEET and on the Label (Figure 2.11). The position of
the power select switch on the Power Supply card (SW2 in Figure 6.40a) should also be checked. The
power selector switch must be in 110 position when input voltage is +24 V DC.
The primary DC power is connected to a separate terminal strip 39/40/41 on the Power supply card marked
POWER (Figure 6.40a). The terminals are marked 39/+24V, 40/0 and 41/ground symbol.
The power terminals +24V and 0 are directly connected to the transformer primary loop, and galvanically
separated from the rest of the instrument. The ground terminal (41) is connected to the bottom plate of the
Indicating Transmitter, to the transformer shield winding and to the outer shield of the interconnecting
cable.
