local IT support for ethernet connection.

Consult the network administrator to verify compatibility of ethernet configura-

tion.

Step 9 Connect Probe/Cable Assembly

Either a YSI 5561(DO & temp) or YSI 5562 (DO, temp, conductivity, pH & ORP)

probe/cable assembly can be used with the 5200A. Both probe/cable assemblies

have an MS19 connector (Military Spec). Connect the probe/cable assembly as

described below.

Directions to Connect Probe/Cable Assembly

Perform steps 1 - 4 of 5200A installation.

1.

Line up pins and guides with the holes and indentations on the cable con-

2.

nector at the bottom of the YSI 5200A - figure 3.30.

Hold the cable firmly against the cable connector; then, turn the locking

3.

mechanism clockwise until it snaps into place. (Remove the cable from

the instrument by turning the cable connector counterclockwise until the

cable disengages from the instrument.)

CAUTION

: Do not ground the probe body.

Lightning and Surge Protection

AC line voltage surge suppressors protect field equipment on any AC line-to-ground

from damage due to electrical transients induced in the interconnecting power lines

from lightning discharges and other high voltage surges. Surge protection devices

are strongly recommended to protect your equipment from secondary surges and

lightning on outdoor installations. Follow the recommendations provided when

choosing and incorporating surge protection devices into your operation:

Recommendations:

Surge suppression devices should be located on the AC line supplying

power to the 5200A and any signal lines connecting the 5200A.

The unit should include noise filtering, common mode, and normal mode

suppression and nanosecond reaction time.

Surge suppressors should be internally-fused to remove the load if the unit

is overloaded or the internal protection fails.

Signal line suppressors protect low voltage signals and relay outputs from

damage due to electrical transients induced in the signal lines from light-

ning discharges or nearby electrical devices.

Signal line suppressors should be installed at each end of an analog loop.

Relay outputs should be protected at the receiver end.

Signal line suppressors should consist of a three-element gas tube followed

by metal oxide varistors and suppressor diodes.

The protective elements should be matched such that high-energy surge

voltages trigger the gas surge arrester, while low energy or surge voltages

affect the MOV’s and suppressor diodes.

Lightning protection devices should be located as close to the 5200A as

possible and wired in accordance with the

National Electric Code in ap-

proved watertight enclosures.

CAUTION: This or any other installation procedure cannot protect against a

direct lightning strike. YSI Incorporated cannot accept liability for damage

due to lightning or secondary surges.
