Ethernet (TCP/IP) Module Communication
The optional serial to ethernet device must be installed on the 5X00 control board
when using TCP/IP for communication. Installation instructions are provided with
the optional serial to ethernet device.
Notes:
- See Menus → System → Communications → Ethernet - page 93 for configura-
tion information.
- An SMTP server accessible by the local network must be provided for eth-
ernet connection.
Consult the network administrator to verify compatibility for ethernet configura-
tion.
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 5X00 and any signal lines connecting the 5X00.
• 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 lightning
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.
Installation and Wiring
• Lightning protection devices should be located as close to the 5X00 as pos-
sible and wired in accordance with the National Electric Code in approved
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.
Sealants, Desiccants, and Securing 5X00
Environmental conditions can promote the formation of condensation in and around
the 5X00. It is very important to follow the steps below to prevent damage to the
electronic components and extend the life of the 5X00 system.
1. Place solid rubber grommets in bulkhead fittings that have no electrical
connections.
2. If using optional conduit fittings (YSI p/n 065926UL) in place of bulkhead
fittings, industrial encapsulant (YSI p/n 065921 conduit sealer) must be
used to prevent moisture from entering the 5X00 enclosure. Apply the
sealant after all wiring and connections are complete. Failure to use
industrial encapsulant may result in damage to the 5X00.
3. Desiccant pack must be replaced whenever the 5X00 enclosure is opened
(Desiccant pack, YSI p/n 006506). Desiccant absorbs moisture captured
within the enclosure.
4. Ensure that the rubber gasket is seated between front panel and enclosure
whenever enclosure is closed.
5. Replace front panel making sure that ribbon cable is not trapped in the
gasket channel before inserting mounting screws.
6. Tighten mounting screws, making sure not to cross thread. The screws
are stainless steel and the receiving threads are brass. Do not over-
tighten!
WARNING: The 5X00 utilizes sensitive solid-state devices that can be damaged
by static shock. Installers must observe accepted ESD (Electro-Static Discharge)
procedures while connecting cabling to the 5X00 I/O plate or any other internal
component or damage may result.
AVERTISSEMENT : le modèle 5X00 utilise des appareils transistorisés sensibles
pouvant être endommagés par des décharges d’électricité statique. Les installateurs
doivent observer les procédures de protection acceptées contre les décharges
électrostatiques lors du câblage à la carte d’E/S du modèle 5X00 ou à tout autre
composant interne afin d’éviter tout risque de dommage.
