Weidmuller RI4 - Multi channel signal transmitter / display - Handbuch (Seite 23)


Locate the instrument in an area that is free from dust, moisture and
corrosive gases.
PowerSupplyRequirements
Check the power supply against the model number before applying
power to the instrument. Multiplus modules must be used with a
suitable mains Power Supply, ratings are as follows:
Voltage Range Nominal Voltage Maximum Power Frequency Fuse
90-250 V AC - 14 VA 47-63 Hz 500 mA
90-250 V DC* - 14 VA -
20-35 V DC* 24 V DC 14 W (at 24 V DC) - 1 A
*Using a DC power supply that provides this voltage will comply with
the instrument’s UL/CSA listing.
Since the power supply is permanently connected, the building wiring
must be connected through a suitably marked switch or circuit breaker
in close proximity and within easy reach of an operator.
Symbols
The instrument labels use symbols in accordance with IEC61010-1:
- Consult documentation; - Direct Current; and - Both
direct and alternating current.
Connections
Strip wires to  mm from the ends. Use a suitable ferrule for multi-
stranded wires (do not solder).
Use 1-8 AWG Cu Wire rated for temperatures above 0 °C Only,
tighten to 4.5 lb-In.
For effective protection from electromagnetic noise, all signal cables
must be shielded, or located on conductive trays or in conduits.
