5. Complete other wiring to 5200A.
6. Close front panel - page 40.
7. Test AC power.
Test AC Power
Turn on main power. e enabled sensor values will display on the Run Screen aer
the initial YSI splash screen. If applicable, install and congure DC power backup
page 45. Verify AC power at the Menus → System →Version menu - page 129.
See Power Fail Menu - page 121 for AC power event log information.
Wire DC Power and backup power
e 5200A may be powered by most 9.0-16.5 VDC source that provides 800mA of
current and is isolated from mains supply by double or reinforced insulation. e
DC power source is user-supplied and can come from a variety of choices including
lead acid, gel cell, or UPS (with 12VDC transformer) external batteries. DC power
wires are terminated at location B on the I/O Board - gure 3.18.
Notes:
- e 5200A does not charge batteries. Quality assurance maintenance
procedures should be established if batteries are to be fully powered when
used as back-up power source.
Installation and Wiring
- Power supply voltage above 16.5 VDC may permanently damage the
5200A.
- When back up voltage falls below 9.0 volts, the 5200A 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 manufacturer’s safety and installation instructions when providing power to

d’eectuer le câblage. Suivez toutes les consignes de sécurité et d’installation du
fabricant lorsque vous fournissez de l’alimentation au modèle 5200A par un bloc
d’alimentation à courant continu.
1. Perform steps 1 - 3 of 5200A installation.
2. Open front panel - page 39.
3. Feed DC power cable through drilled hole in rubber grommet to location
B. The terminal strip is removable.
