Power Supply Requirements

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

trip wires to 7 mm from the ends. Use a suitable ferrule for multi-

stranded wires (do not solder).

se 12-28 AWG Cu Wire rated for temperatures above 70 °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.
