Transport
Transport weight Refer to the delivery documents for the weight of the transport unit.
After receipt of delivery:
Checking the transport
unit
• Check the transport unit for damage.
• Major damage must be documented photographically.
• Ensure that any damage to the transport unit is confirmed by the transport company in writing
Scope of delivery
Delivery includes:
• 3TM vacuum contactor
• Operating instructions
• Device-specific circuit diagrams
• Connector (accessory pack)
Unpacking
Working equipment Required tools: Knife/scissors.
Opening the transport unit • Place the transport unit on a level, non-slip and pressure-resistant surface.
• Open the box.
• Check that the delivery is complete.
• Check the vacuum contactor for damage.
Note
Observe stacking height
For transport, no more identical transport units may be stacked on top of each
other than indicated on the transport unit.
Observe loads specified on the transport unit.
Note
Secure load
For transport, secure the load in such a way that the transport unit is not at risk.
Note
Do not use the vacuum contactor if parts are broken, i.e. if you find cracks, flaking,
bent metal parts, damaged plug-in contacts, tears, or bare cables.
Send it back in its original transport unit (see “Reuse of transport unit”, page 6).
Note
Transporting the vacuum contactor
Transporting the vacuum contactor by holding and lifting the auxiliary switches on
the sides (23) leads to material damage.
Only transport the vacuum contactor by holding it under the operating mechanism
box (34), the base plate (2), or the pole shells (7).

Reuse of transport unit
Reusing the transport unit The box and the filler materials can be reused if the vacuum contactor is to be trans-
ported again.
• Pack the vacuum contactor in reverse order.
• Close the box.
Due to the low weight, no lifting eyes are provided. The
vacuum contactor can be lifted and transported without
tools.
The fastening eyelets (*) can be used for lifting with a
crane. Watch for shifting weight!

Storage
1) In the storage conditions given above, the capacitors must be reformed after
one year. To do so, apply rated supply voltage via terminal A1/A2 of the electronic controller for at least 20 minutes.
Note
During transport and storage, the vacuum contactor must be in the following condition:
• OPEN switching position
• Unlatched condition (only if unlatching is available).
Note
Risk of corrosion damage if stored improperly!
The vacuum contactor can be stored for up to a year in its transport unit if the storage conditions listed below are met.
If the storage conditions are not met, the vacuum contactor cannot be stored any
longer than 6 months in the transport unit.
If storage of longer than one year is planned, unpack the vacuum contactor from
the transport unit. Further storage must ensure that the vacuum contactor cannot
be damaged.

General information
Smooth and safe operation of this switching device requires proper transport and
storage, professional installation and assembly, as well as careful operation and
maintenance.
The operating instructions are an integral part of the switching device and contain
all information for commissioning and use.
The basic version and all listed configurations of the vacuum contactors 3TM are
type-tested devices as per IEC 62271-1 (see also “Standards”, on page 10)
WARNING
Dangerous electrical voltage and mechanical movements
When electrical devices are operated, certain parts are inevitably live under
dangerous voltage, and mechanical parts may move very quickly, also
when remotely controlled.
If the warnings are not observed, serious injury or material damage may be the
result.
Only personnel with the relevant qualifications may work on or in the vicinity of
this device. These personnel must be familiar with all warnings and servicing activities specified in these operating instructions.
CAUTION
Material damage caused by electrostatic discharge to the electronic controller
Electrostatic discharge can cause material damage to the electronic controller
and restrict its functionality.
To prevent damage to electronic components, discharge any existing electrostatic charges on hands or tools by touching grounded surfaces prior to touching
electronic components and before removing the connector plugs.
Note
In the event of subsequent attachments or fittings, e. g. locking parts in connection with switchgear, ensure that
• fast moving parts are not additionally loaded with masses or forces and
• additional parts have sufficient clearance, in particular, from moving and live
parts.
If the vacuum contactor is to be equipped with additional functions by the customer, we recommend consulting the factory, since tried and tested solutions are frequently available.

Installation position
Observe the distances as per IEC 60071 insulation coordination or comply with the
required leeway distances according to the national operational requirements.
- Front side: High-voltage section with protection class IP00.
- Rear side: Low-voltage section with protection class IP20.
Installation position The vacuum contactor 3TM can be installed in four positions.
1) Wall mounting, vertical
2) Supine position, horizontal
3) Wall mounting, vertical, rotated 180°
4) Suspended, with reduced parameters (after consultation with manufacturer)
*) Observe distance to high-voltage and grounded components!
Fig. 5 Mounting position
High-voltage section The high-voltage section consists of an autonomous pole shell, which can receive
the correspondingly dimensioned vacuum interrupter.
Solenoid actuator The vacuum interrupter is actuated by a common solenoid actuator. This solenoid
actuator has a very low holding capacity in continuous operation.
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 control 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).
