1) Number of gas channels
2) Range, units and gas type for each channel
3) Alarm level(s) for each gas channel
4) Tag Name for each channel
5) Assignment and set-up information for each relay contact
NOTE: The set-up configuration is fully field-programmable and can easily be executed by the user in the
field by following the instructions within this Operators Manual. Modifications to the set-up configuration are
expected to take place at the customers site due to requirement changes and/or system expansions.
3.0 Installation
Securely mount the Model 1600/6400-N1P enclosure in a suitable panel opening. The recommended opening
cut-size is 9”W X 7.25”H and the required depth is 14”.

Figure 3 Unit Mounting and Dimensional
Connect 110/220VAC input wiring to the terminals labeled “ACV (L1)”, “Neutral (L2)”, and “Ground” (See
Figure 5). The Power Supply is capable of handling AC inputs from 100-240VAC 50-60Hz without
degradation.
If applicable, connect 24 VDC to the terminals labeled “24VDC” and “DC Comm”, in Figure 5. This input
can be used for primary power or back-up power in the event of AC power failure.
Where applicable, connect the RS-485 wiring from remotely located I/O devices to the terminals located on
the Back Panel. These terminals are labeled RS-485 “A” (+), “B” (–), and “Shld” (shield) for primary RS-485
communication (Figure 5). RS-485 wiring should consist of a two conductor, shielded twisted pair (Belden
cable P/N 9841 is recommended). Also available are two output terminal blocks to provide 24VDC to external
RS-485 devices. This power should be used only to power remotely located I/O modules and/or sensors, and
should not exceed a total of 3-3.5Amps accumulative for all I/O modules and sensors attached to the
controller. (I.E. if there are two modules mounted on the enclosure that have an accumulative current draw of
0.5Amps, the sensors qnd/or I/O modules connected to the output 24VDC should not exceed 3.0Amps.) Refer
to each module and sensor manual for maximum expected current draw from each.
