Safety instructions
Target group:
For skilled electricians and suitable
qualified, instructed personnel in
accordance with national legislation,
including the relevant standards.
The GHG 521 plugs and sockets are not
suitable for explosion hazardous areas.
They shall be used for their intended
purpose and in perfect and clean condition.
Prior to taking the plugs and sockets into
operation, they will have to be checked in
accordance with the instruction as per
section 6. The sockets may only be used in
undamaged condition.
Observe the national safety rules and
regulations for prevention of accidents as
well as the safety instructions included in
these operating instructions and set in
italics the same as this text!

Conformity with standards
The apparatus are conform to the standards
specified in the EC-Declaration of conformity,
enclosed separately.
References to standards and directives in these
operating instructions always relate to the latest
version. Other additions (e.g. details relating to
the year) shall be observed.

Field of application
The plugs and sockets GHG 521are suitable
for use in heavy industrial areas acc. to
IEC/EN 60309!
The enclosure materials employed, includ-
ing the exterior metal parts, are made of
high-quality materials which ensure a corro-
sion protection and resistance to chemical
substances corresponding to the require-
ments in a “normal industrial atmosphere”:
- impact resistant polyamide
- glass-fibre reinforced polyester
- special steel AISI 316 L.
In case of use in an extremely aggressive
atmosphere, please refer to manufacturer.
5 Use/Properties
The GHG 521 plugs and sockets are used for
the power supply of local controls with varying
locations, as well as of electrical installations,
mobile machinery and driving gear in industrial
areas. Acc. to IEC they are used up to max. 16A
(see page 7, technical data).
The plugs and sockets can generally be
used for the voltage range laid down in
IEC/EN 60309 (e.g. UN 400V that corresponds
to the voltage range 380-415V).
The apparatus connected to the plug shall
be suitable for the applied mains voltage.
Taking into operation of the wall sockets,
except "2 pole + PE switched":
Fig. 1: In order to activate the socket, first
the bayonet ring item 2 is to be screwed off
the socket item 1 and to be folded open.
Fig. 2: After pushing the plug into the socket,
the bayonet ring of the plug item 2 is screwed
to its stop onto the socket in order to establish
IP 66 protection category.
For operating the 4-pole wall socket (with
interlocking switch) proceed as follows:
Fig. 1 and fig. 2, as described above.
Fig. 3: The switch item 3 is switched on,
thereby locking the plug in the socket.
After switching on the socket, the bayonet ring
item 2 of the plug is screwed to its stop onto
the socket item 1 in order to maintain the
protection category acc. to the type label also
whilst the plug is inserted.
For operating the 2-pole with PE wall
socket (switched by plug) proceed as
follows:
In order to switch on the socket, the plug is
inserted, pushed fully home and then turned
through approx. 45° to the right. Thereby the
plug is locked in the socket (see fig. 3.1).
Valid for all wall sockets
Proceed in inverse order to switch off and pull
the plug from the wall socket with switch. After
having removed the plug from the socket, close
the latter with the folding cover and secure it
with the bayonet ring in order to establish IP 66
type of protection.
In order to ensure the socket's type of
protection acc. to the type label also with the
plug being inserted, the bayonet ring of the plug
(fig. 2, item 2) is turned to its stop onto the
socket.
The plug can be pushed into the socket
and pulled out of it only whilst the wall
socket with switch is switched off.
