Cooper Crouse-Hinds GmbH
Explosion protected control units made of plastic or
stainless steel type GHG 44.
At option, the Ex 29 control switches are
provided with a fitted locking device so that
they can also be padlocked.
The 4 pole pushbutton contact can be added
with the standard CCH actuators. If the 4
pole pushbutton contact is added with an
Emergency STOP Mushroom-head
pushbutton actuator, then you have to use
the actuators with CCH order number
GHG 410 1437
This actuators can be recognize by the red
thrust washer and black inserting sign.
The data as per point 3 and 4 will have to
be taken into account with the use.
Applications other than described are not
permitted without CEAG / Cooper Crouse-
Hinds's prior written consent.
For the operation, the instructions stated
in section 7 of the operating instructions
will have to be observed.

Installation

For the mounting and operation, the
respective national regulations (e. g. Betr.Si.V,
equipment safety act) as well as the general
rules of engineering will have to be observed.
6.1

Mounting

The plastic and stainless steel control units
can be mounted without opening their
S4
enclosure.
44
When being mounted directly onto the wall,
the control units shall rest evenly only at the
43
fastening points provided for them. The
chosen screw shall match the fastening hole
44
(see dimensional drawing, page 10 + 11 and
Fig. 2, page 15).
43
42
They shall not damage the hole (e.g. use of a
washer).
41
If the screws are overtightened, the plastic
44
control units may be damaged.
43
The plastic control units GHG 444 2, 448 2,
449 2 and GHG 447 2. are suitable for
44
fastening onto CEAG / Cooper Crouse-Hinds
apparatus holders by means of self-cutting
43
screws (see fig. 4-8, page 16).
The respective mounting instructions will have
to be observed.
inserting sign
Mounting the wall mounting brackets onto the
black
stainless steel control units GHG 444 3, 448 3,
449 3 and GHG 447 3 is done as per fig. 2 + 3
in page 15.
Observe the min. No. of wall mounting
brackets!

The electrical connection of the apparatus may
only be carried out by skilled staff. The circuit
diagram of the built-in components is either
shown on these components or attached to
them or shown in the operating instructions. As
to wired control units, the circuit diagram
attached to the device is to be observed.
After the hinged framework has been folded
out in order to facilitate the introduction of
cables or the connection to the terminals
arranged under the hinged framework, it shall
again be fitted properly in place.
If, for the sake of an easier wiring, the built-in
components (AM 72 and AM 45 measuring
instrument, push-button base, signal lamp
base, control switch base, potentiometer base
etc.) are snapped off the top hat rail fitted in
the hinged framework, the components will,
thereafter, have to be properly re-inserted in
the lock-in position on the top hat rail of the
hinged framework.
! ! ! ! !
The total number of used conductors and
internal wiring conductors, can be found out
in the wiring table page 24.
In order to snap off the components
(including measuring instruments AM 72 and
AM 45), the snap-in hooks are unlocked by
pulling them outwards.
Mind: The lock-in positions of the built-in
components shall match the notches on
the top hat rail!
In order to maintain the explosion category,
the conductors will have to be connected with
special care.
The insulation shall reach up to the terminal.
The conductor itself must not be damaged.
The connectible min. and max. conductor
cross-sections will have to be observed (see
technical data).
All screws and/or nuts of the supply terminals,
also of those remaining vacant, shall be
tightened down.
The fitted optional standard terminals are
designed for direct connection of conductors
with copper cores.
Switching on the axis of the Ex 23 and
Ex 29 control switch base whilst the
enclosure is open, is not permitted (in
order to be able to properly close the
switch again).
On measuring instruments for c.t. connection n/
1A (fig. 1, item 2, page 13) the interchangeable
scales can be changed via a flap arranged on
the upper part of the measuring instrument (fig. 1,
item 1, page 13).
