1 General

These operating instructions describe the safe and

proper way to work with the device. The safety

information 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 instrument 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 CP..THERM heaters are manufactured according to

8 Installation

NOTICE

Carefully remove

When removing from the packaging and during

transport, the connection line must not be stressed or

bent.

For free convection, the heater needs to be installed with

ribs standing vertically. The minimum distances to the

floor and to devices above it must be complied with. The

label needs to remain legible.

If an additional TAE thermostat is switched in series,

then it can be attached to the surface of the heater

(thermal coupling). The minimum distance also needs to

be adhered to here. Refer to the following drawing.

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

permissible bending radius = 5 x outer diameter into

consideration.

Illustration2: 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.

9 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

preceded 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

integrated thermostat, the fuse protection can be

selected according to the cross-section of the supply

cable.

Operating Instructions CP MICROTHERM DC.A

Page 6 / 11 HOM2540241291Ien-0

Additional equipotential bonding is required. The

terminal block designated for this purpose has the

ground sign.

ATTENTION:

Never remove the

adapter/ cable gland!

Illustration3: Example heater with KLE connection

CAUTION

NOTICE: Do not remove adapter/ cable

connection 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.

10 Commissioning

If the heater is installed in accordance with the notes in

the Installation [}Page 5] section and Connection [}

Page 5] sections, then the radiator may be

commissioned.

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

installation instructions are not adhered to.

11 Maintenance

The design of the device does not require any

maintenance.

Functional and safety test intervals can be freely

selected 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 GB

3836.13-2013 must be complied with.

12 Troubleshooting

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

continuity test on the heating circuit. Pay attention to the

connection diagram and switching point of the

thermostat!

In the case of overheating, the thermal indicator (see

figure) indicates a discoloration. If more than four fields

are blackened, the heater must be uninstalled and

returned to the manufacturer for inspection.

Illustration6: Temperature indicator

13 Deinstallation

Disassembly may only be carried out by a trained

person.

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.

14 Disposal

Disassemble the components of the product, taking the

applicable local labour protection and environmental

regulations into consideration and make sure that the

components are recycled:

• Scrap metal

• Send plastic elements to recycling
