The following safety instructions must be observed and apply to all subsequent
chapters. The safety instructions must always be observed in addition to the instruc-
tions given in the individual sections.
High-voltage
Checking the vacuum contactor in the panel with applied high voltage is allowed only
after full functionality has been determined (see“Commissioning” on page 37).
Note
Product liability claims are valid only if the spare parts purchased have been re-
placed by qualified personnel.
The necessary operating instructions for retrofitting, removal and installation
must be followed.
DANGER

Installation site
Observe distances according to IEC 60071 insulation co-ordination or comply with
the required air distances depending on the national operational requirements.
- Front side: High-voltage section with protection class IP00.
- Rear side: Low-voltage section with protection class IP20.
Installation site The vacuum contactor 3TM can be installed in four positions.
Fig. 8 Installation site
1) Wall mounting, vertical
2) Supine position, horizontal
3) Wall mounting, vertical, rotated 180°
4) Suspended, possibly with reduced parameters (after consultation with manufacturer)
*) Observe distance to high-voltage and grounded components!
High-voltage section The high-voltage section consists of autonomous pole shells, which can receive the
correspondingly dimensioned vacuum interrupters. This makes variable distances
between the pole centres possible (120 mm and 150 mm).
Solenoid actuator The vacuum interrupters are actuated by a common solenoid actuator. This solenoid
actuator has a very low holding capacity in continuous operation. The vacuum inter-
rupters work synchronously in the same direction.
The solenoid actuator and the shunt release of the vacuum contactor 3TM can be
actuated with AC or DC.
Vacuum contactors 3TM work according to a defined closing and opening time,
which can be configured and extended by an additional closing and opening delay.
Both delay values are independent of each other and are added to the closing and
opening times.
Electronic controller The electronic controller controls the supply of energy to the solenoid actuator on
closing. The closing current is controlled to a specified level. The current is switched
to the holding current after a specified time. The holding current reduces the vacuum
contactor’s energy supply during operation.
The voltage supply of the magnetic unlatching is not affected. The customer is to
deal with the signal control. The maximum signal duration is to be observed, since
the shunt release solenoid only has a limited continuous current strength of 500 ms.
The inrush current (peak) is dependent on the supply voltage.
Supply voltage terminals The electronic controller has terminals for the following:
• supply voltage A1/A2
as well as independent thereof
• the release voltage for the magnetic unlatching E1/E2 (optional).

Fig. 9 Terminals A1/A2 and optionally E1/E2 of the electronic controller
The electronic controller also allows the configuration of additional closing and open-
ing delays. If no configuration is selected, only the natural closing and opening time
of the switching device is active.
The configuration is delivered ex works according to the option ordered.
For adjustments to the secondary voltage, the customer can reset the configuration
via a 6-pole DIP switch S2 on the electronic assembly. (matrix, see chapter “Config-
uration of supply voltage Ua of the electronic controller”, p. 45).
Auxiliary switch The auxiliary switches are mounted on the side of the operating mechanism box and
are not wired. The wiring is carried out on the customer’s premises using spring bal-
ancer or screw terminals.
Mechanical closing
latching
(Applies only to vacuum contactors with closing latching)
When the vacuum contactor is closed, the mechanical closing latching is activated.
The solenoid actuator is held and automatically separated from the supply voltage
once the latching position is reached.
Switching in the de-energised holding mode (supply voltage circuit A1/A2) is carried
out automatically via the electronic controller.

Electromagnetic unlatch-
ing and manual unlatching
(Applies only to vacuum contactors with closing latching)
Unlatching is done via:
• Electromagnetic unlatching, remote-controlled or
• Manual unlatching via push rod or draw bar.
The remote tripping is carried out via the electromagnetic shunt release Y1 (9). If
manual unlatching (emergency-stop) via a push rod (12) or draw bar (15) is not
available, the shunt release Y1 can be carefully manually actuated from the rear
side of the vacuum contactor in a de-energised state and for test purposes (see de-
tails in Fig. 11).
Manually operated unlatching (emergency-stop) is performed with a push rod (12)
or draw bar (15) with approx. 30 N. The customer is to mount M4 threaded rods for
the push rod or draw bar with fitting end pieces or other suitable terminators. Tight-
ening torque 3 Nm
Subsequent ordering If no latching or unlatching is available but is planned for backfit, the following mod-
ules can be subsequently ordered and mounted:
• Mechanical closing latching with shunt release Y1
• Manually operated unlatching mechanical system (emergency-stop) with push
rod or draw bar
See chapter “Connecting low voltage”, p. 30.
A description of the installation is only supplied with the operating instructions of the
retrofit kit.
