After preparing a 92 X 92 mm cut in the panel, remove the rails from the
Indicator and slide its rear through the cut until its front reaches the panel. Place the
rails again in the Indicator from the back of the panel and tighten the screws as

2.2 - Electrical Installation
DMY-2015 Indicator may be powered by voltage between 90 and 240VAC or
130 to 340VDC, any polarity. Remember that the internal circuit is powered
whenever the instrument is connected to the external power supply.
Input and output signals must be connected to the instrument only when it is
turned off.
Figure 3 shows the instrument rear terminals for connection of power supply,
ground, communication, process input and output signals.
Signal wiring must be kept far away from power wires.
Due to its metal case the instrument ground should be connected to earth
ground. Never connect the ground to neutral terminal.
