should not be connected to the TP-SYS. The power supply providing the
12 VDC must have its own backup source.

Power connectors
The maximum input current is 2.7 A. The gauge is dependent on the length
of the wire. The TruPortal System Controller can be powered by an internal
18 VAC transformer that uses 20 AWG (0.812 mm / 0.518 mm
2
) secondary
wires. The earth ground connection at CN2 Pin 2 is not required if the
controller board is grounded through the mounting screws.
Note:
These specified ranges have been verified by UL. Note that if
you run a longer wire, it is not verified by UL.
This equipment must be permanently connected to a mains fused spur (3 A
or 5 A) using 3-core cable with each core being no less than 18 AWG (1.024
mm / 0.823 mm
2
). The mains cable should be clamped securely with the
cable clamps provided within the equipment/installation kit. Knockouts are
provided on the top, bottom and sides of this equipment and these are
intended for conduit or cable glands. As a mains switch is not provided on
the equipment, a readily accessible disconnect device shall be incorporated
in the building installation wiring. Where there is doubt as to the phase of
this wiring, the device, when operated, will disconnect both poles
simultaneously.
