Installation

Note: This installation procedure is for guidance only, and its suitability should be verified by the installer.

SAFETY PRECAUTIONS

= WARNING! - Information which is essential for preventing hazard to personnel or device and must be read with care.

= DANGER! - High voltage area. Isolate power supply before any maintenance work.

The following safety precautions are strongly recommended:

1. Before attempting to install and operate the unit, read the instruction and installation manual carefully.

2. Installation and any maintenance should only be carried out by suitably qualified personnel.

3. It is recommended that the unit be connected to the mains supply via a suitably rated isolating switch.

4. WARNING: When the unit is connected to the mains supply and the cover is open, the circuits at mains voltage will be
exposed. Therefore when installing the unit, ensure all required connections (including battery connected, if included), are made and
covers replaced before turning on the mains supply. Ensure that all the connections made are secure. If any maintenance work e.g.
installing a new battery, is required ensure that the unit is isolated from the mains supply before removing the cover. Never leave the

unit unattended if the cover has been removed and the mains supply is connected.

5. Do not exceed unit ratings as shown on the ratings label.

6. It is advisable to route mains cables away from low voltage or sensor cables.

(i) THX Unit

Note: For viewing comfort, the unit should be positioned at eye level. The ambient temperature of the unit is (0°C to +40°C). It is always good practice to keep
electronic equipment away from cold, heat and electrical plant, as extremes of temperature may reduce the lifetime of the device, and heavy electrical loads,
switches, relays or contactors too close to the device may cause electrical and electro-magnetic interference when switched on or off.

(ii) Sensors

The THX may be used with a variety of sensors of different cable lengths. If required, sensors are available with extended cable lengths or
alternatively, sensor extenders are available also in a variety of lengths. If the sensors need to be extended, but factory-made extenders are
not available, they can be extended using a suitable 3 or 4 core cable, according to the diagram shown below

Please note however, that as with all PT100 sensor applications, a good connection is vital. It is therefore recommended that wherever there
is any doubt, a factory extended sensor or sensor extender should be used.

(iii) Alarm Relay

Note: The alarm relays are 2 contact arrangements which are isolated (volt-free). These relays may be used to trigger an external bell, warning lamp or digital
communicator (telephone dialler).

Max rating of Alarm relays is 5A @ 240 VAC.

The alarm relay is software configurable to accommodate normally open or normally closed operation, as described below.

Normally Closed Operation – This is the default mode.

Normally Open Operation – In this mode, the relay outputs will break contact (open circuit) in the event of an alarm and make contact
(closed circuit) in the event of power failure.

If the external device is used, connect the alarm as appropriate, according to the diagram opposite.

Installation

(iv) Power Connections and Wiring Diagram

Note: This device should be properly earthed. Flexible wires simplify connection to the terminals. All connections should be secure and adequately tightened.
It is good practice to keep mains cables away from sensor cables and other low voltage signal cables.

Connect the supply to the unit, as per diagram below, using the appropriate input voltage according to the application.

(v) Battery

The battery supplied is a 3.7V Lithium-polymer rechargeable battery and is plugged in but switched OFF. This should be switched ON
after installation. See picture below. This battery is not essential for the system operation, but is used in the case of power failure, thereby
continuing to log the 12 sensor inputs for approximately 6 hours.

The system parameters will remain intact, in the event of a power failure, however all interface options (Ethernet, screen, keypad options,
USB etc. will not function as normal)

It is recommended that the battery is changed every 24 months, in order to maintain good power failure backup operation. When replacing,
ensure that the type of rechargeable battery used is as specified.

Installation

WALL MOUNT

1. Drill four holes in the wall, according to the template and insert
the wall plugs

2. Remove the Front Lid by unscrewing two screws

3. Disconnect the modules

4. Separate the front cover by unscrewing two screws

5. Remove the required knock outs from Back Box for the cables
to pass through (always separate front cover before removing
the knock outs)

6. Insert the cable glands

7. Screw in the Back Box to the wall

8. Pass the cables through the glands

9. Mount the Front Cover on the Back Box

10. Insert the modules

11. Connect the power supply cable and sensors

12. Tighten the cable glands

13. Mount the front lid

- An inlet or insulating liner with a smooth rounded opening

- A cord guard made from an insulating material should be firmly
attached to the device. The insulating material should extend
beyond the inlet by at least five times the overall diameter of
the cord with the largest cross-sectional area that can be
used to supply the device. Where the conductors are
connected inside the device, the cord anchorage will relieve
the conductors of the cord from excessive strain, this includes
twisting. The anchorage must also protect the insulation of
conductors from abrasion. The protective earth conductor
must be the last suffer from any strain in the event the cord
should slip in its anchorage. The anchorage must provide relief
from a pull force of 30 Newton and a twisting or torque force
of 0.10 Newton metres. Cord anchorage shall meet the
following requirements.

WARNING: TO PROTECT THE MAINS SUPPLY LEAD FROM ABRASION AND SHARP BENDS AT THE POINT WHERE

THE LEAD ENTERS THE DEVICE, ONE OF THE TWO FOLLOWING METHODS MUST BE EMPLOYED:

- A screw that comes into direct contact with the cord will not
be used to clamp down the cord.

- The cords will not have any knots tied in it.

- It will not be possible to push the cord into the device to such
an extent that it will cause a hazard.

- Should the cord insulation fail in an anchorage that has metal
parts, none of the exposed conductive material of the device
will become live.

- A compression bushing will not be used as cord anchorage
unless it is capable of accommodating all sizes and types of
mains supply cord that meet the requirements in point (2) and
are suitable for connection to the terminals of the device, or
the bushing has been designed to terminate a screened
mains supply cord.

- The cord anchorage will be designed in such a way that cord
replacement does not cause a hazard and will be clear how
strain relief is provided.

PANEL MOUNT (required panel mount kit)

1. Cut a hole in the panel with the described dimensions,
(see page 7)

2. Remove the Front Lid unscrewing two screws

3. Disconnect the modules

4. Separate the front cover by unscrewing two screws

5. Remove the required knock outs from Back Box for the cables
to pass through (always separate front cover before removing
the knock outs). Ethernet cable can be passed through the
hole which is under the label on the front cover (see picture
below)

6. Attach the Panel Mount Seal, ensure that it is on the right position

7. Insert the Back Box into the panel cut out
