The MessageView terminal accepts power supply voltages from 18
to 30 V DC (24V DC nominal). The terminal’s power consumption
is 20 W max. (833 mA @ 24 V DC). Electronic circuitry and an
internal fuse protect the terminal from reverse polarity and
over-voltage conditions.
Note: If the MessageView terminal is connected with reverse
polarity, the terminal will not operate but is not damaged. As soon as
the polarity is corrected, the terminal will operate normally.
!
ATTENTION: Do not connect the MessageView
terminal to an AC power source. Connecting to an AC
power source will damage the terminal.
!
ATTENTION: The MessageView terminal is
designed for safe use when installed in a NEMA Type
12, 13 (4x indoor use only), IP65 enclosure.
To connect DC power to the terminal:
1. Unplug the 3-position removeable terminal block from the
bottom rear of the terminal.
Note: A terminal block connector plug is provided with each
terminal. For additional plugs, order Replacement Part No.
