Note
:
The factory presets the voltage divider to 20:1. To change the voltage divider to a di erent setting, refer
to the section on the next page.
The factory-installed internal voltage divider provides a maximum of 18 V
under open circuit conditions. This is an impedance-protected functional
extra low voltage (ELV) output to prevent shock, energy, and re under
normal conditions at the machine interface receptacle and under single fault
conditions with the machine interface wiring. The voltage divider is not fault
tolerant and ELV outputs do not comply with safety extra low voltage (SELV)
requirements for direct connection to computer products.
Note
:
The cover on the machine interface receptacle prevents dust and moisture from damaging the receptacle
when not in use. This cover should be replaced if damaged or lost.
Installation of the machine interface cable must be performed by a quali ed service technician. To install
a machine interface cable:
1. Turn OFF the power and disconnect the power cord.
2. Remove the machine interface receptacle’s cover from the rear of the power supply.
3. Connect the machine interface cable to the power supply.
