Installation; Mounting - Eaton Crouse-Hinds Série Mode D'emploi

With measuring instruments for c.t. connection,
the pick-up current is indicated indirectly, with
direct indication instruments it is indicated directly.
Control switches with direct-indicating
measuring instruments are fitted with looping
terminals for looping the PE conductor and
phases not fed via the measuring instrument
(see technical data for temperature class,
explosion group and permissible ambient
temperature).
The control switches are generally fitted with a
locking facility and can be locked in the OFF or
left position by means of a padlock to prevent
unauthorized switching (shackle diameter of
padlocks up to 5 mm see fig. A).
Other locking positions can be set according to
separate conversion instructions.

The data according to sections 3 and 4 shall
be taken into account during use.
Applications other than those described are
not permissible without a written declara-
tion of consent from Messrs. CCH / CEAG.
During operation the instructions stated in

Mounting

The control switches can be mounted without
opening the enclosure.
When the control switches are mounted
directly onto the wall, they shall rest evenly only
on the fastening points provided for this
purpose.
The screw chosen shall fit the fixing hole (see
dimensional drawing) and shall not damage the
hole (e.g. use of a washer).
The apparatus shall be fixed diagonally with a
minimum of 2 screws.
If the screws are overtightened, the
apparatus may be damaged.
The control switches are suited for plug-in
mounting on CCH / CEAG apparatus holders,
sizes 2 and 2A for switches of the type GHG
292 and size 3 for switches with measuring
instruments of the type GHG 293, whereby
they are pushed into the guide groove from the
top of the apparatus holder.
See the respective mounting instructions.
