ELECTRICAL CONNECTIONS
1. The user must rigidly observe the Local Electrical Regulations.
2. Do not make any connections to the unused terminals for making a tie-point for other wires (or for any other reasons) as
they may have some internal connections. Failing to observe this may result in permanent damage to the indicator.
3. Run power supply cables separated from the low-level signal cables (like Thermocouple, RTD, DC Linear Current/Voltage,
etc.). If the cables are run through conduits, use separate conduits for power supply cable and low-level signal cables.
4. Use appropriate fuses and switches, wherever necessary, for driving the high voltage loads to protect the indicator from
any possible damage due to high voltage surges of extended duration or short-circuits on loads.
5. Take care not to over-tighten the terminal screws while making connections.
6. Make sure that the Indicator supply is switched-off while making/removing any connections or removing the Indicator from
its enclosure.
CONNECTION DIAGRAM
The Electrical Connection Diagram is shown on the top side of the enclosure. The diagram shows the terminals viewed from
the REAR SIDE with the controller label upright. The connecters provided for wiring are pluggable male-female type. The
female parts are soldered on the controller PCBs while the male parts are with screws and removable. The rear panel
electrical wiring connection diagram is shown in Figure 10.1.
