Schedule
 EQUIPMENT:
Equipment and systems covered by this certificate are as follows
 
 
Subject and type:

Heater type DH..M0.-.
Type designation to DH.*1.*2M0.*3.*4 -.*5

1):    Usable for heating medium
F: fluids
G: gases / air
K: heating element encapsulated with solid body
 
2):Type accordance with the purpose
0*: Component
 
3:Enclosure category / type or variation number
1, 2, 3, 4, 5, 6, 7, 8
 
4):Type of enclosure material
 
5):Index number for rated power


Description:

The heater type DH...-. is designed in the type of protection Flameproof Enclosure "d" and Protection by enclosure "t".
The heater enclosures consist of two parts each that are screwed together by means of an inch-long thread. The tubular part of the enclosure serves the purpose of housing the heating coils. This part is filled with magnesium oxide and sealed in a highly solid manner. The other part serves the purpose of fitting a cable entry. The heating is connected by means of a cable permanently installed in the heater enclosure.

 EQUIPMENT(continued):
 
 
Parameters:

Main circuit:
Rated voltage max.AC/DC 800 V
Rated current max.20 A
Size of conductor max.4 mm²
 
Maximum ambient temperature range:    -60 °C up to +60 °C


Schedule of Limitations:

The temperature class, a control unit if required (level, flow) and further conditions of use (ambient temperature, self-heating, heat conduction, fitted position etc.) all have to be defined when testing the entire heating system.
The apparatus shall only be connected using the lead fitted. This lead has to be connected observing the instructions provided. The connecting space in a potentially explosive atmosphere has to meet the requirements of an acknowledged type of protection according to IEC 60079-0.
The equipotential bonding has to be established via the nipple, flange or the bushing.
The heater has to be mounted in such a manner that it will be protected against mechanical stress.
The lengths of the flameproof joints are in parts longer and the gaps of the flameproof joints are in parts smaller than the values of table 1 and 2 of IEC 60079-1:2007. For information of the dimensions of the flameproof joints contact the manufacturer.
