Installation, Start Up and Shut Down DF-760E 27
CAUTION
A 220 VAC power cord is not supplied with the analyzer. The customer supplied
220 VAC power cord should be rated for 250 VAC, 10 Amps and be equipped
with an IEC 60320 C13 connector for connecting to the analyzer. This power
cord provides the protective ground for the analyzer so it must have a protective
earth wire. Ensure that the power cord is plugged into a properly grounded
outlet. The power cord should have the appropriate safety agency approvals for
your location.
Plug the line cord (supplied with 110 VAC units only) into the receptacle at the back of the
analyzer. Connect the line cord to the power source.
4.1.9 Hydrogen Service Safety System
This optional system is designed to safeguard the DF-760 from explosion hazards when
operating on hydrogen sample gas under normal pressure and flow conditions as detailed
in the Operating Instruction Manual. The instrument chassis and the remote pump, if
equipped, are both protected by maintaining a safe condition within their respective
enclosures. If installed, this option impacts the electrical wiring, gas plumbing and
operation of the analyzer. See page 173 for additional installation and operation
information.
NOTE, if equipped with the Hydrogen Safety Service System, when shipped from the
factory the analyzer will be configured through the GSF screen to measure hydrogen. As a
result, the Hydrogen Safety Service System will be enabled out of the box.
