2.0 Installation Instructions
2.1 Safety Information
Before installation please read the safety information below.
2.1.1 Warning
Suitably qualified personnel must install the equipment and care must be taken, as high
voltages may be present on the instrument terminals. The instrument must be mounted in a
position that provides protection behind the panel to at least IP20. Local regulations regarding
electrical installation should be rigidly observed.
2.1.2 Isolation
The power supply terminals and associated internal circuitry are isolated from all other parts
of the equipment, in accordance with EN61010-1, for connection to a category II supply
(pollution degree 2). Any terminals or wiring connected to the input or output, which is
accessible in normal operation, must only be connected to signals complying with the
requirements for Safety Extra Low Voltage (SELV) circuits.
Follow wiring instructions described later in this section.
2.2 Unpacking your dew TEC DS2000 Dewpoint Meter and Sensor
Once unpacked, the items should be examined for any obvious external damage. Any
evidence of damage or mishandling should be notified to your carrier immediately.
The items should include
dew TEC DS2000 dewpoint meter, Moisture Sensor packed in a
metal canister, instruction manual, sensor connecting cable and any optional extras if ordered.
The sensor is packed separately in a waterproof metal canister, with desiccant, to protect it
from excessive moisture exposure during transit. The sensor should be inspected for damage
then immediately stored in its canister until ready for installation. Retain the packaging for
future use, ensuring the sensor canister cap is tightly screwed to preserve the desiccant.
2.3 Sensor Care
Very special care must be taken not to damage the sensing element, for example by touching
or making any other physical contact, as this may damage the sensing surface and render the
Sensor useless.
Additionally, the following guidelines should always be followed:
•
For any reason whatsoever DO NOT REMOVE THE SENSOR GUARD OR
ATTEMPT TO CLEAN THE SENSING ELEMENT WITHIN IT. The Sensor is
NOT user serviceable and does NOT contain any user replaceable parts. In the event
of a problem follow the problem guide at the end of this manual.
