Directions to Ground 5X00
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 5X00 installation.
2. Open front panel - page 41.
3. Remove screw from location
F
or
G
.
4. Feed ground wire through drilled hole in rubber grommet and to location
F
or
G
on metal plate covering I/O Board. Ground wire gauge must conform
to all locally applicable electrical codes.
CAUTION: Run high and low voltage cables through separate bulkhead and
conduit.
5. Install a ring (eyelet) or spade (fork) terminal onto the ground bare wire
before terminating ground wire to F or G.
6. Return screw at
F
or
G
over terminal connection of ground wire.

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 41.
Step 4 Wire Power
5X00 instruments are available with either AC or DC power. The DC version can
only be powered by DC power. The AC version can be powered by either AC or
DC.
If an AC version is properly wired and configured for AC and DC backup, and
AC power fails, the instrument will be powered by the DC backup which supplies
backup power
. 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 41.
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.
