For ER 405, Eh 147 and EN 104 cables (see drawings, paragraphe 2.8 and 2.9), EMC type stuffing
gland are used.
1. Strip the conductors from the various cables.
2. Remove the lid of the power supply housing by unscrewing its six screws.
3. Pass the cables into the stuffing gland by proceeding as follows
(see Figure 2-6)
:
a. Unscrew element
Counterclockwise. Element
must not be removed from the
housing.
b. Remove joints
and
from element
. These two elements allow the stuffing gland
to adapt to various diameters of cable. Element
Can be removed from element
by
simply pushing it outwards.
c. Pass the cables through elements
,
(if used),
.
d. Strip the cable (outer sheath) to the elements
output and cut the shield over 5-8 mm
as show in
Figure 2-7.
Pass the stripped cable through the element
.
e. Connect the shield on the metallic part of element
as show in
Figure 2-7.
f. Reassemble the elements of the stuffing gland (take care that the shield remains in
place) and, before replacing element
, lubricate the seal
with silicone as indicated
in
Figure 2-6
. Tighten element
so that it projects beyond joints
and/or
to provide
the degree of seal required.
4. Connect the conductors of the various cables to the terminals of the power supply unit.
5. Replace the cover of the power supply housing and tighten its six screws.
