PREFACE
Electric discharge
The EXA analyzer contains devices that can be
damaged by electrostatic discharge. When servic-
ing this equipment, please observe proper pro-
cedures to prevent such damage. Replacement
components should be shipped in conductive pack-
aging. Repair work should be done at grounded
workstations using
grounded soldering irons and wrist straps to avoid
electrostatic discharge.
Installation and wiring
The EXA analyzer should only be used with equip-
ment that meets the relevant international and
regional standards. Yokogawa accepts no respon-
sibility for the misuse of this unit.
The instrument is packed carefully with shock
absorbing materials, nevertheless, the instrument
may be damaged or broken if subjected to strong
shock, such as if the instrument is dropped. Handle
with care.
Although the instrument has a weatherproof
construction, the transmitter can be harmed if it
becomes submerged in water or becomes exces-
sively wet.
Do not use an abrasive material or solvent when
cleaning the instrument.
Do not modify the PH202 transmitter.
Electrostatic charge may cause an explosion haz-
ard. Avoid any actions that cause the generation of
electrostatic charge, e.g., rubbing with a dry cloth.
Warning label
Because the enclosure of the pH/ORP transmitter
Type PH202S-E, -P, -F are made of aluminium, if it
is mounted in an area where the use of category
1 G Zone 0 apparatus is required, it must be
installed such, that, even in the event of rare inci-
dents, ignition sources due to impact and friction
sparks are excluded.
