If greater sample flow is required for improved response time, install a bypass in the sampling system upstream of the analyzer input.
EXHAUST OUT:
Exhaust connections must be consistent with the hazard level of the constituent gases. Check local, state, and federal laws, and ensure that the exhaust stream vents to an appropriately controlled area, if required.
ZERO IN and SPAN IN (Optional):
These are additional ports for inputting span and zero gas. There are electrically operated valves inside for automatic switching between calibration and sample gases. These valves are completely under control of the 3000ZA electronics. They can be externally controlled only indirectly through the remote cal inputs as described below.
Pressure, flow, and safety considerations are the same as prescribed for the SAMPLE IN inlet above.
3.3.2Electrical Connections
For safe connections, no uninsulated wiring should be able to come in contact with fingers, tools or clothing during normal operation.
CAUTION: USE SHIELDED CABLES. ALSO, USE PLUGS THAT PROVIDE EXCELLENT EMI/RFI PROTECTION. THE PLUG CASE MUST BE CONNECTED TO THE CABLE SHIELD, AND IT MUST BE TIGHTLY FASTENED TO THE ANALYZER WITH ITS FASTENING SCREWS. ULTIMATELY, IT IS THE INSTALLER WHO ENSURES THAT THE CONNECTIONS PROVIDE ADEQUATE EMI/RFI SIELDING.
3.3.2.1 Primary Input Power
The power cord receptacle and fuse block are located in the same assembly. Insert the power cord into the power cord receptacle.
CAUTION: POWER IS APPLIED TO THE INSTRUMENT'S CIRCUITRY AS LONG AS THE INSTRUMENT IS CONNECTED TO THE POWER SOURCE. THE RED 
SWITCH ON THE FRONT PANEL IS FOR SWITCHING POWER ON OR OFF TO THE DISPLAYS AND OUTPUTS ONLY.
