GAS 222.21 Ex2

DANGER

Adiabatic compression during gas blowback (explosion hazard)!

Adiabatic compression may cause high gas temperatures and must be checked by the
user.
Gas blowback may result in high gas temperatures due to adiabatic compression. This
can cause flammable gases to ignite spontaneously.

a) Blowback of explosive atmosphere / gases is prohibited.

b) Flammable atmosphere / gases (non-explosive) may only be blown back with nitro-

gen (inert gas).

4.9 Electrical Connections

WARNING

Hazardous electrical voltage

The device must be installed by trained staff only.

CAUTION

Wrong mains voltage

Wrong mains voltage may damage the device.
Regard the correct mains voltage as given on the type plate.

CAUTION

Equipment damage

Cables damaged
Do not damage the cable during installation. Install a strain relief for the cable connec-
tion. Secure the cable against twisting and loosening. Please note the temperature res-
istance of the cables (> 100 °C/212 °F).

Only use cables with a temperature resistance of > 100 °C (212 °F) to connect to power. Make sure the connecting cable has suffi-
cient strain relief (match cable diameter to the seal on the cubic plug/cable fitting).

Please note, the heating system briefly has high starting currents (max. 6 A). Use a suitable fuse (8 A). When connecting, also ob-
serve the applicable explosion protection regulations (e.g. IEC/EN 60079-14).

4.9.1 Version Without Terminal Box

The probe includes two cubic plugs per EN 175301-803. The plug is configured so it cannot be connected reversed. For safety reas-
ons this configuration must not be modified.

One plug is used to power the two heating cartridges (power supply (115/230) VAC, 50/60 Hz, see type plate), the other plug is for
the temperature switch (alarm output).

The supply line cross-sections must be suitable for the rated current. Use a maximum line cross-section of 1.5 mm

2

and a cable

diameter of 8-10 mm.

Connect the power supply and the intrinsically-safe temperature switch per the connection diagram.

Connect optional probe accessories directly to the respective power supply.

4.9.2 Version With Terminal Box

This probe version includes a terminal box. All electrical connections are factory connected to the terminals in the terminal box.

Connect the respective power supply for the two heating cartridges, the intrinsically-safe temperature switch and the optional
accessories to the terminals per the connection diagram.

The probe may only be operated using the Ex e cable fittings and the terminal box closed. Never change the terminal assign-
ment.
