5.2 Electrical installation
Two-part connectors are used for permanently connected wiring. The free (or cable end)
connector may be unplugged from the panel to assist wiring. Terminals are of the cage clamp
quick connect type; use a screwdriver or similar implement to press down on the orange tab
to open the clamp and allow the stripped wire end to be inserted. The terminals will accept
0.2 to 2.5 mm
2
(24 to 14 AWG) insulated wires, which should be stripped 10 mm. After
insertion of the wire, ensure that no bare conductor is visible, no strands of the conductor
are protruding from the wire entry of the terminal and that the conductor is held securely in
the terminal.
Cables should be routed to pass out through the slot at the bottom of the door. Ensure cables
are not trapped when closing the door.
5.2.1 Mains power supply connections
Mains power supply connection is at the upper left of the front panel.
The Tankvision Gauge Link is double insulated, and thus does not require connection of a
protective earth for safety reasons. An earth terminal is included in the mains supply
connector for EMC purposes. This should be connected to the earth/equipotential conductor
of the supply.
