Warning!
LASER CLASS 1 as per IEC/EN 60825-1 (2001).
The devices must not be repaired, changed or mani -
pulated. In case of defect, the product must be always
replaced by an original one.
If the seal of the housing cover or a seal of the cable
entry is damaged, it should be replaced with a new hous-
ing cover or cable entries of the manufacturer.
The insulation must reach up to the terminal. The con-
ductor itself must not be damaged.
Fine-wired cables must be secured with a cable lug. If
two cables must be led to a common terminal, a double
cable lug must be used.
Generally only certified cable entries and sealing plugs
must be used. Trumpet shaped cable glands or other
suitable entries with additional stress relief must be used
for flexible cables. Assembly guidelines, which are signif-
icant for cable entries, must be observed. When using
cable entry with an IP protection class, which is lower
than the one applicable for the device, IP protection
class of the entire device must be reduced. Non-used
inlet openings must be sealed with a certified sealing
plug for getting the minimum protection class. When
installing the cable entries, ensure that seal inserts suit-
able for the cable diameter are used during installation.
For excisable seal inserts ensure that the insert is suit-
able for the cable diameter.
All non-used cable entries must be sealed with sealing
plugs certified for cable entries. The fibre optic cables
are introduced through glands with slotted seals so that
pre-assembled fibre optic cables can be used. Permissi-
ble cladding diameter of the fibre optic cable must be
complied with.
(for this see technical data, cable glands, page 54).
Cable entries must be tightened for ensuring the required
minimum protection class (for this see technical data,
test torque, page 55). Excessive tightening may impair
the protection class.
When tightening the cap nut of the metal cable entries
(type E1WF/e), the gland must be secured against rota-
tion with the help of a suitable tool.
The device must be operated only at the specified ambi-
ent temperature and at the specified relative humidity
(not condensing).
The housing may be opened under voltage in zone 1. The
IP30 cover of the terminals must
not
be opened under
voltage. The IP-30 cover
must be replaced after repairs or maintenance. All non-
covered control elements such as switches may be
actuated. The fibre optic cable may be plugged or
removed under voltage.
The devices must not be repaired, changed or manipulat-
ed. In case of defect, the device must be always
replaced by an original one.
For dust explosion protection, safety measures, which
are same as gas explosion protection are applicable. The
housing must
not
be opened under voltage if there is
dust explosion hazard. Before opening the housing, the
dust deposits must be removed and electric voltages
must be switched off.
1.10 Operation
The national regulations are applicable for service, main-
tenance and testing of associated equipment.
No maintenance is required if the device is operated
properly taking into consideration the assembly instruc-
tions and ambient conditions.
According to the ordinance on industrial health and safe-
ty the operator of the electrical systems in explosion haz-
ard areas is obliged to get these tested from a qualified
electrician for their proper condition.
