SAFETY GUIDELINES AND IMPROPER USE
Do not leave this User’s Manual in the switchgear box during
operation!
• Do not operate X450DA2/d switchgears in SNM
mine areas ( NM3) according to ČB Decree No.
22/1989 Coll., or in explosive atmospheres
(hazardous conditions 1) according to ČSN EN 1127-2.
• Do not operate X450DA2/d switchgears in Zone 0
explosive gas atmospheres (ČSN EN 60079-10-1) and
Zone 20 and 21 explosive dust atmospheres (ČSN EN
60079-10-2)
• The cable glands must always be in the Ex “d” design
(flame-proof enclosure) according to ČSN EN 60079-1
• In the case of cable entry through cable glands with a
sealing ring, only use compact and round cables with
sheathing made of thermoplastic, thermoset or
elastomeric materials. The bedding and sheathing
must be extruded and the bedding material, if used,
non-absorbent. The cable must be at least m long!
• There may be parts with hot surfaces, i.e.
hazardous temperature inside the X450DA2/d
switchgear. Open the switchgear only in the
absence of explosive atmospheres and in a non-
voltage state after a sufficient time since its
deactivation to allow the hot parts to cool.
• X450DA2/d switchgears are not designed for non-
professional use. Installation, start up and any service
whatsoever must be performed by workers with
professional expertise and in conformance with safety
regulations.
• Operate X450DA2/d switchgears in accordance with
the following operating conditions, technical and label
data.
• Do not replace the existing internal equipment of
the switchgear with equipment inconsistent with
the documentation supplied with the product (e.g.
replacement of an existing 6A circuit breaker with a
10A circuit breaker).
• If the switchgear contains a current protector,
regularly verify their function at least every 6
months using the test button (while observing
applicable safety regulations).
• Some mining cables (e.g. type CBEH) have individual
wires provided with a semi-conductive removable layer.
Always remove this layer before connecting the
wires!
• Switching and protective devices inside switchgears
may produce short-term electromagnetic
interference and therefore have to be used in
industrial zones, where they do not have a negative
impact on other equipment.
• Carry out storage, transport, assembly, installation,
revision and preventive maintenance, repairs and
service in accordance with the instructions stated
hereunder.

4. INSTALLATION INSTRUCTIONS
4.1. Switchgear attachment – dimensions
4.2. Cable entries
For direct cable entry (in a flame-
proof enclosure), use only
appropriate explosion-proof
cable glands certified as Ex
equipment. You can use cable
glands sealed with a sealing
compound (barrier glands) or
cable glands with a sealing ring. In the case of entry through cable
glands with a sealing ring, carefully choose an appropriate cable –
see Safety guidelines and improper use. The cable used must be at
least m long.
Each cable gland seals only a certain range of cable diameters. In the
case of a larger number of cable glands on the box flange, always
insert and seal the cable in the cable gland gradually from one side
(e.g. from left to right) and always start with the cable glands on the
bottom row and then continue with the cable glands right above them.
For easier installation of cable glands, you can request special
tightening pliers – see fig. To attain reliable protection of cable glands,
tighten them properly with the specified torques.
Blank unused holes with certified plugs with the respective ingress
protection and explosion-proof design.
4. . Connecting wires to terminals
Wires can be connected using spring-cage terminal blocks or screw
terminal blocks.
4. .1 Spring-cage terminal blocks
By compressing the spring-cage (1) e.g.
with a suitable screwdriver (or special
WAGO screwdriver, which is supplied only
upon customer request), release the
window for attaching the wire. Insert the
wire (2) and release the spring cage (3),
which will lead to a perfect current-
carrying connection. Always equip
stranded wires with end ferrules.
Termination of stranded wires with soft
solder (Pb-Sn) is not allowed!
When interconnecting two
neighbouring terminal blocks with a
spring cage using special blade terminals, press this terminal with
force into both terminal blocks so that the terminal does not extend
beyond (see following fig.). In the case of some types of spring-cage
terminal blocks, connecting a wire with a ferrule requires the use of a
terminal block with a connection cross-section one grade higher than
the wire cross-section. E.g. a 2.5mm
2
wire with a ferrule requires the
use of a 4.0mm
2
terminal block.
4. .2 Screw terminal blocks
Connect the wires to the
side of the terminal block
and tighten the connection
properly. When
interconnecting screw
terminal blocks (see
following fig.), tighten the
screw terminals properly.
4. . General requirements
The following applies to both types of terminal blocks: only one wire
may be inserted into one outlet and its maximum cross-section must
not be larger than the nominal cross-section of the terminal block. The
wire insulation must reach as close as possible to the actual current-
carrying connection and the wire itself must not be damaged in any
way.
We recommend treating protective conductor connection points (or
other metal surfaces subject to corrosion) regularly with lubricating
grease at least once a year (according to the operating atmosphere).
Connect unused wires without voltage to empty terminals (including
protective ones) or terminate them in other ways according to
applicable regulations.
5. INSTALLATION ACCORDING TO APPLICABLE
REGULATIONS
The decision to use a given type of equipment in the areas
considered must be in accordance with the above operating
conditions (see section 2.), local operating regulations, ČB Decree
No. 75/2002 Coll. (for mining equipment with danger of presence of
methane), ČSN EN 60079-14 (for Group II equipment) and other
related regulations.
Apart from the above stated regulations, protection against injury
due to electric shock is also stipulated by ČSN 332000-4-41,
ČSN EN 61140 and other related regulations.
Safety regulations for operation and work on electrical equipment
are stipulated by ČSN EN 50110-1.
Professional competence of workers in electrical engineering is
stipulated by Decree No. 50/1978 Coll., as amended.
6. REVISION AND PREVENTIVE MAINTENANCE
Revision and preventive maintenance of explosion-proof electrical
equipment is stipulated by ČB Decree No. 75/2002 Coll. (for mining
equipment with danger of presence of methane) and ČSN EN 60079-
17 (for Group II equipment), unless specified otherwise e.g. by a
decree, local regulations.

always clean it and coat it with a thin layer of K3 ČSN 65 6911
grease for corrosion protection.
Cleaning of enclosure surfaces can only be performed with non-
metal scrapers and corrosion-free liquid.
Re-lubrication of the enclosure surface must be performed at
least once a year. Switchgears must have all electrical and
mechanical connections secured against self-release. However,
vibration tests of equipment (external influences AH1, 2, 3 according
to ČSN 33 200-5-51) in relation to climatic condition classes
according to ČSN EN 60 721-3-3 and ČSN EN 60 721-3-4 are not
performed. For Group I mobile equipment, it is therefore
recommended to perform regular revisions according to Annex 2
to ČBÚ Decree No. 75/02 Coll., and for Group II equipment
according to ČSN EN 60079-17 at least twice a year at the level of
detailed inspection.
Cable glands and plugs may only be replaced with those with the
corresponding explosion-proof design (see Technical data) and
ingress protection and certified by the respective notified body.
Where it is not possible to secure fixed installation of cables,
cable glands must be also in the version secured against cable
tension (with a clamp) – this especially applies to mobile
equipment.
Other spare parts, see Article 10.
7. REPAIRS AND GENERAL INSPECTIONS, SERVICE
Repairs and general inspections of explosion-proof electrical
equipment are specified by ČB Decree No. 74/2002 Coll., (for Group
I mining equipment) and ČSN EN 60079-19 (for Group II equipment).
Repairs should preferably be entrusted to the manufacturer or its
authorized organization which, in the case of repairs of explosion-
proof mining equipment, must have valid authorization according to
the aforementioned ČB decree.
