5.4.2 Connecting the Sensor Power Supply
WARNING!
Ensure the cabling is not connected to control unit power during wiring.
WARNING! – ELECTRIC SHOCK
This equipment contains lethal voltages!
Do not reverse Live (L) and Neutral (N) – the neutral line is not fused!
Hazardous voltages are still present when the main power supply fuse has failed!
The label on the PSU cover and the markings on the power connector indicate the voltage required.
Connect only to a power supply with a voltage corresponding to that on the rating plate.
Connecting the Cables
Easily accessible disconnect devices, such as switches or circuit breakers along with a separate fuse, must be
fitted to the power supply wiring for mains-powered sensors. These must be located so they can be reached easily
(within a 2 m/6½ ft radius of the unit). The isolation devices should connect/disconnect both mains Live (L) and mains
Neutral (N) and must be clearly marked as the disconnecting device for the instrument.
5.4.3 Wiring the Mains Power Supply
1. Undo the 4 off screws and open the hinged sensor enclosure lid.
2. Note the label on the power supply/PSU cover (see Figure 3 below).
3. Referring to Figure 4 on the next page, undo the 2 off screws and remove the PSU cover.
4. Route the power supply cable through the right-hand cable gland and connect to the mains power terminals as
outlined in the following table.
