menu - page 148.
See
power fail menu
- page 138 for AC power event log information.
Wire DC Power and Backup Power
The 5X00 may be powered by most regulated 9.0-16.5 VDC sources that provide
800mA of current and are isolated from mains supply by double or reinforced
insulation. The DC backup power source is user supplied and could be lead acid,
gel cell, or UPS (with 12VDC transformer) external batteries. DC power wires are
terminated at location
B
on the I/O Board - Figure 3.18 (Common lettering refer-
ences are used for both 5400 and 5500 models).
Notes:
-
The 5X00 does not charge batteries. Quality assurance maintenance proce-
dures should be established if batteries are to be fully powered when used as
back-up power source.
-
Power supply voltage above 16.5 VDC may permanently damage the 5X00.
-
When back up voltage falls below 9.0 volts, the 5X00 ceases to operate properly.
-
Some switching DC power supplies not supplied by YSI may result in noisy
readings.
Directions to Wire DC Power/DC Backup Power
