In addition to grounding the 5200A, all tanks should be electrically grounded via
a ground probe.
Directions to Ground 5200A
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 - 2 of 5200A installation.
2. Open front panel - page 40.
3. Remove screw from location
E
.
4. Feed ground wire through drilled hole in rubber grommet and to location
E
on metal plate covering I/O Board. Ground wire gauge must conform
to all locally applicable electrical codes.
5. Install a ring (eyelet) or spade (fork) terminal onto the ground bare wire
before terminating ground wire to
E, F
or
G
.
6. Return screw at
E, F
or
G
over terminal connection of ground wire.
CAUTION: Run high and low voltage cables through separate bulkhead and
conduit.

Installation and Wiring
Step 4 Wire Power
The 5200A 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 the 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 5200A 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
L
on I/O Board - figure 3.17.
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 5200A installation.
2. Open front panel - page 40.
3. Feed AC power cable through drilled hole in rubber grommet to location
L.
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”
according to applicable local electrical codes. Use minimum 18 gauge,
3 wire power cord.
CAUTION: It is recommended to power only the 5200A instrument with the
power cord to prevent exceeding the current draw of the AC power supply.
