7. Terminate other end of the earth ground wire to a cold water pipe, steel rod,
copper pipe, or earth ground.
8. Complete other wiring to configure 5X00 system.
9. Close front panel - page 43.
Step 4 Wire Power
The 5X00 is available as an AC or DC instrument. The DC version can only be
powered by DC power. The AC version can be powered by either AC or DC power.
If an AC version is properly wired and configured for both AC and DC power, and
AC power fails, the power switches to 12VDC. If DC voltage drops below a user
defined safe operating range, an alarm occurs.
CAUTION: At 120VAC, the 5X00 draws 25 watts (~0.2 amps). Use wiring
suitable for that load following all safety information and local electrical codes.
Back up power is recommended when operating with AC power. Backup power
can be supplied by 12VDC or UPS battery source.
Wire AC Power
The AC power option includes an integrated universal (worldwide) AC switching
power supply allowing AC power from any AC receptacle 100-240VAC. AC power
wires are terminated at location O on I/O Board - Figure 3.17. (Common lettering
references are used for both 5400 and 5500 models).
Directions to Wire AC Power
WARNING: Disconnect external power to the unit before wiring.
AVERTISSEMENT : déconnectez l’alimentation externe de l’unité avant d’effectuer
un câblage quelconque.
1. Perform steps 1-3 of 5X00 installation.
2. Open front panel - page 42
3. Feed AC power cable through drilled hole in rubber grommet to location
O. The terminal strip is removable.
CAUTION: Run high and low voltage cables through separate bulkhead and
conduit.
4. Terminate AC power wires to pins “G” (ground), “L1”, and/or “L2/N” ac-
cording to applicable local electrical codes. Use minimum 18 gauge 3 wire
power cord.
CAUTION: It is recommended to power only the 5X00 instrument with the power
cord to prevent exceeding the current draw of the AC power supply.

7. Test AC power.
Test AC Power
Turn on main power. The enabled system values display on the Run Screen after
initial YSI splash screen. If applicable, install and configure DC power backup page
48. Verify AC power at the Menus → System →Version menu - page 135.
See power fail menu - page 128 for AC power event log information.
