1 General

These operating instructions describe the safe and

proper way to work with the device. The safety informa-

tion and instructions given as well as the local accident

prevention regulations and general safety regulations

valid in the area of application must be complied with.

These instructions are a constituent part of the instru-

ment and need to be kept in the immediate vicinity of the

device accessible to personnel at all times.

Before starting any work, the operating instructions

should be read in full.

2 Use

The SL..THERM heaters are manufactured according to

Directive 2014/34/EU and are licensed for direct heating

through flange-mounting (conduction) or for room heat-

ing (convection) in Ex-zone 1 and Zone 2 for instrument

categories G/ D in temperature classes T3 to T6. You

will find the temperature class for your device on the la-

bel. See Technical Data [}Page4] section.

The areas of application are:

• Frost protection

• Condensation protection

• Maintaining temperature

As an option, thermostats can be integrated in the con-

necting cable. If a TAE is used, the respective operating

instructions must be complied with.

EC type examination certificates PTB 02 ATEX 1116 X

with appendices and supplements in German and Eng-

lish, as well as IEC Scheme Certificate IECEX PTB

07.0055X.

7 Installation

NOTICE

Carefully remove

When removing from the packaging and during trans-

port, the connection line must not be stressed or bent.

Free convection may not be impeded. You will find the

minimum distances and installation position in the follow-

ing figure.

The label needs to remain legible.

Please make sure that the absolute heat transfer coeffi-

cient of the surrounding housing is not smaller than 0.5

W/K.

To ensure operational safety, the heater must operate

under temperature conditions which will NOT exceed the

trigger temperature of the limiter.

The operating temperatures must be adhered to.

The connection cable must be permanently installed up

to the inlet into the on-site junction box, taking the per-

missible bending radius = 5 x outer diameter into consid-

eration.

In the dust Ex area, the applicable requirements of EN

60079-14 must be complied with.

Illustration1: Installation example MICROTHERM with TAE or

TS and clearance

Additional installation material, such as rails or panels

and also junction boxes, are not included in the standard

scope of delivery (see Installation accessories [}Page4])

and must be ordered additionally.

8 Connection

INFO

The device may only be connected up and secured by a

trained person, taking into account the "rated voltage"

and "rated current" specified on the nameplate.

Where operating voltage = measured voltage (rated

voltage), then the heater is at its rated output. Mains

voltage fluctuations up to 10 % are then permissible.

Each heater with integrated TS thermostat must be pre-

ceded by a 10 A fuse or a motor protection switch with

short-circuit and thermal quick release (set to 10 A) as

short-circuit protection. When using a heater without in-

tegrated thermostat, the fuse protection can be selected

according to the cross-section of the supply cable.

Additional equipotential bonding is required. The ter-

minal block designated for this purpose has the ground

sign.

In a TT or TN system, a residual current device (RCD)

must be used where the measured triggering residual

current does not exceed 100 mA. Residual current

devices with a measured triggering residual current of 30

mA are preferable. In an IT system, an insulation monit-

oring device needs to be used which switches off the

supply as soon as the insulation resistance is no greater

than 50 Ω per Volt of the rated voltage (refer also to DIN

EN 60079-14; section 7.4).

ATTENTION:

Never remove the

adapter/ cable gland!

Illustration2: Example heater with KLE connection

CAUTION

NOTICE: Do not remove adapter/ cable connec-

tion to connect up the heater!

This would cause irreversible damage to the heater and

this would mean that the explosion protection can no

longer be warranted.

The illustration may deviate from the heater.

9 Commissioning

If the heater is installed in accordance with the notes in

the Installation [}Page 4] section and Connection [}

Page 5] sections, then the radiator may be commis-

sioned.

CAUTION

Sufficient heat dissipation must be ensured.

Unauthorized covers must be removed as otherwise

there is the risk of the heater overheating.

The heating circuit is permanently disconnected by a

temperature melt fuse which can't be reset if these in-

stallation instructions are not adhered to.

10 Maintenance

The design of the device does not require any mainten-

ance.

Functional and safety test intervals can be freely selec-

ted by the operator in accordance with the applicable

regulations.

Repairs may only be carried out by the manufacturer in

the factory.

All components have to be kept clean and free of dust

and harmful substances that could lead to excessive

temperature rise.

In the dust Ex area, the applicable requirements of EN

60079-17 and EN 60079-19 must be complied with.

11 Troubleshooting

If the heater fails, check the installation. Carry out a con-

tinuity test on the heating circuit. Pay attention to the

connection diagram and switching point of the thermo-

stat!

12 Deinstallation

Disassembly may only be carried out by a trained per-

son.

DANGER

Risk of fatal injury from electric current!

If contact is made with live components, there is the risk

of fatal injury.

For this reason, switch off the voltage supply, secure

against being switched on again and check that no more

voltage is present.

Disconnect connection line from the clamps and from the

connection socket, disconnect device from bracket and

remove it.

13 Disposal

Disassemble the components of the product, taking the

applicable local labour protection and environmental reg-

ulations into consideration and make sure that the com-

ponents are recycled:

• Scrap metal

• Send plastic elements to recycling

• Sort other components according to their material

properties and dispose of them.

NOTICE

Environmental damage may be caused if dis-

posed of incorrectly!

Electrical scrap and electronics components are subject

to hazardous waste treatment and must only be dis-

posed of by certified specialists!

The local community authorities or specialist waste dis-

posal companies can provide information on environ-

mentally friendly disposal.
