Installation and Maintenance Instructions
for ZT11 High Purity Transmitter

5.4 Storage Precautions

• To avoid failure or damage, do not store
product under the following conditions:
• Do not expose to water
• Susceptible to adverse effects due to air
pressure, temperature, humidity, ventilation,
sunlight, particles, salt or sulfur in the air
m
CAUTION:
• Do not expose to inclination, vibration or
shock (including during transportation)
• Do not expose to chemicals (chemicals'
storage area) or gas
• Do not expose to direct sunlight or high
temperature
• Deformation and discoloration of resin parts
may occur when product is stored in a
sealed bag under high temperature and high
humidity environments.

6. WIRING

6.1 Wiring schematic of mating connector
Wire connection and external connection should be carried
out as follows.
Insert the cable with M12 connector (optional) while aligning
to the connector groove on the instrument.
Hand-tighten until the nut does not move. [Tightening
torque: 0.4 to 0.5N
m]

When connecting equipment that can generate surge from the
same power supply, it is recommended that a voltage-depen-
dent resistor (varistor) be connected to the pressure transmitter
for protection. In addition, take the following precautions when
wiring:
•
Do not pull or bend the cable with excessive
force.
•
When mounting, check the specification rat-
ing of the product and determine the power
supply rating to be used. Once the product
load resistance has been verified, use the
connected device's internal resistance within
its rated range.
•
When soldering, take care that the soldering

iron does not touch the sheath of the case
