Installation and Maintenance Instructions for

ZX11 Non-Sparking High Purity Transmitter

top of the instrument (Refer to "5. Outline

drawings"). Unit will not provide prescribed

performance if the air inlet is obstructed/

blocked.

• Do not apply excessive force or excessive

bending to the cable once the connector

is attached to the product and the mating

connector.

• Snoop test of the sensor part should be

avoided as this may cause an insulation

resistance defect.

• Prior to commencing operation, it is

recommended to purge the unit with

sufficient inert gas. This will remove any

atmospheric component, particles, and/or

foreign matter within the pipe

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

• Do not expose to inclination, vibration or

CAUTION:

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

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
