Wire DC Power and Backup Power
e 5X00 may be powered by most regulated 9.0-16.5 VDC source that provides
800mA of current and is isolated from mains supply by double or reinforced insula-
tion. e DC 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 references are used
for both 5400 and 5500 models).
Notes:
- e 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
WARNING: Disconnect external power to the unit before wiring. Follow all manu-
facturer’s safety and installation instructions when providing power to the 5X00
via a DC power supply.
AVERTISSEMENT: déconnectez l’alimentation externe de l’unité avant
d’eectuer le câblage. Suivez toutes les consignes de sécurité et d’installation du
fabricant lorsque vous fournissez de l’alimentation au modèle 5X00 par un bloc
d’alimentation à courant continu.
1. Perform steps 1-3 of 5X00 installation.
2. Open front panel - page 42.
3. Feed DC power cable through drilled hole in rubber grommet to location
B. Terminal strip is removable.
CAUTION: Run high and low voltage cables through separate bulkhead and
conduit.
4. Terminate DC power wires to pins (-) and (+) according to manufacturer
instructions and any applicable local electrical codes.

5. Complete other wiring to 5X00.
6. Close front panel - page 43.
7. Test DC power.
Test DC Power
Connect DC power cable to power source. e enabled system values will display
on Run Screen aer initial YSI splash screen. Verify DC power at the Menus →
System →Version menu - page 135.
See Power Fail Menu - page 128 for DC low battery trigger monitor and alarm
information.
Note:
- e 5X00 will not power up if DC power supply wires are terminated incor-
rectly.
