GHG 26 �� Main-switch / load disconnect switch
Due to the AC 3 motor switching capacity of the safety switches, reliable
isolation (switching) is also possible during operation
The Main-switch / load disconnect switch (IEC/EN 60947-3) are designed
for the safe isolation of the electrical energy at all poles on equipment,
machinery and drives in potentially explosive atmospheres.

GHG 26 �� Safety switch; maintenance-/repair -switch
Due to the AC 3 motor switching capacity of the safety switches, reliable
isolation (switching) is also possible during operation
The safety switches (IEC/EN 62626-1; class 1) are designed for the safe
isolation of the electrical energy at all poles while maintenance, cleaning
and repair work is being carried out on equipment, machinery and drives
in potentially explosive atmospheres.
The classification according to IEC/EN 62626-1 is given.
The "EMERGENCY-STOP" version conforms to the requirements of
IEC/EN 60204-1.
A built-in locking device prevents the opening of the enclosure in the
"OFF" position.

The safety switches / load disconnect switch (IEC/EN 60947-3) are
designed for the safe isolation of the electrical energy at all poles on

Installation
The relevant national regulations and the generally recognized rules of
engineering apply for the installation and operation (IEC/EN 60079-14).
The improper installation and operation of safety switches may
result in the invalidation of the guarantee.
6�1
Mounting
The switches GHG 26 can be mounted without opening the enclosure.
When being mounted directly onto the wall, the switches GHG 26 shall
rest evenly only at the fastening points provided for them. The chosen
screw shall match the fastening hole (see dimensional drawing) and they
shall not damage the hole (e.g. use of a washer).
The switches GHG 262, GHG 263 and GHG 264 shall be fixed diagonally
with a minimum of 2 screws.
The switches GHG 265 and GHG 266 shall be fixed with a minimum of 4
screws.
If the screws are overtightened, the apparatus may be damaged.
The switches GHG 262 and 263 (3-pole only), are suited for plug-in
mounting on CEAG apparatus holders, sizes 2 and 3, whereby they are
pushed into the guide groove from the top of the apparatus holder
(see fig. 2 and fig. 3).
The switches GHG 263 (6-pole), GHG 264, GHG 265 and GHG 266 are
suited for mounting on CEAG apparatus holders size 3 by means of
self-cutting screws (see fig. 4).
See the respective mounting instructions.
6�2
Opening the device/ Electrical connection
The electrical connection of the apparatus may only be carried out
by skilled staff (IEC/EN 60079-14).
Before opening the apparatus, ensure that it has been isolated from
the voltage supply, or take appropriate protective measures.
Before opening, set the switch to the "ON" position.
The properly bared conductors of cables shall be connected with due
regard to the respective regulations.
To maintain the explosion protection, conductors shall be
connected with special care.
The insulation shall reach up to the terminal. The conductor itself
shall not be damaged.
The minimum and maximum conductor cross sections that can be
connected shall be observed (see technical data).
If desired, the switch GHG 264 (80 A) can be connected using
35 mm² cable lugs (DIN 46 234 / 8-35).
