2. System description
The VARITAIN PushIn Socket System is used for the electrical supply of cooling
containers on board seagoing vessels and riverboats, as well as in harbour systems. It is
suitable for 440V±10% 3-phase, but can also be adapted for other voltages in the
factory. The current loading is suitable for cooling containers up to a maximum of 32 A.
Each socket is protected against short circuits and overloads by an in-built circuit-
breaker. The circuit-breaker trips automatically and must be manually returned to the 0-
or 1-Position.
VARITAIN PushIn is an internationally standardized CEE socket device compliant with
IEC 60309-1 (DIN EN 60309-1; VDE 0623-1), IEC 60309-2 (DIN EN 60309-2; VDE
0623-2) and ISO 1496-2.

3. Description
4.1 Casing
The casing consists of powder coated (color as requested by customer) welded stainless
steel sheet with welded bolts for fixing the components. In order to ensure the degree of
protection IP 67 according to EN 60529, a high quality rubber seal is pressed onto the
upper bent section of the housing.
Fixing lugs on the housing floor are used to fix the equipment.
4.2 CEE socket insert
The CEE socket insert consists of a CEE socket with the contact sleeves (3-phase
sleeves with an earth sleeve), the circuit-breaker (see 1.2.4), the bayonet cap, the
cables and the mechanical actuating elements. Furthermore, the LED unit and, as an
alternative, a pressure compensating element, are installed inside.
The groove for preventing incorrect connection of the CEE socket in respect of the
protective conductor contact defines the voltage and frequency. VARITAIN PushIn is
offered and delivered in its 3-hour setting as standard.
4.3 LED unit
The LED unit is installed in the CEE socket insert and serves as a status signaling
element, indicating that the circuit-breaker has switched. When the LED unit lights up
green, the circuit-breaker is switched on and power is supplied to the CEE socket. The
LED unit does not check whether power is supplied to all three phases.
If the LED unit does not light up, there is no power at the CEE socket.

4.4 Locking system
According to the international regulations the plug can only be plugged in and
withdrawn in the switched off state of the circuit-breaker.
Operation mode:
Power On
Turn the bayonet cap anticlockwise and remove it.
Insert the plug into the socket as far as it will go.
The socket is switched on!
Push the bayonet ring over the socket and tighten it
firmly in a clockwise direction.
Power Off
Release the bayonet ring of the plug by turning it
anticlockwise.
Pull the plug out of the socket.
 The socket is switched off!
Tighten the bayonet cap by turning it clockwise.

Attention:
Please ensure that you only use plugs that conform with international standards
[IEC 60309-1 (DIN EN 60309-1; VDE 0623-1), IEC 60309-2 (DIN EN 60309-2; VDE
0623-2)] are used, as only in this way is the safe operation of the plug device is
ensured. Please particularly ensure that:
- the plug housing is undamaged
- the bayonet ring is present with undamaged seal
- the plug is clean and dry
- the auxiliary protrusion of the plug is present
- the plug is connected in accordance with the valid standards
4.5 Circuit-breaker
Number of poles: 3
Short circuit switch-off capability: Standard 10 kA, 25 kA or 100kA (with current limiter)

Rated current: max. 32 A
The circuit-breaker is fitted with a trip knob that mechanically simulates tripping, as for
e.g. a short circuit or overload.
4.6 Connection terminals
Two types of connection terminal are fitted in the factory for the power supply,
depending on the type and the number of outputs.
Feed-through terminal for 2.5 mm² to 50 mm², tightening torque 4-5 Nm
Bolt terminal for 6 mm² to 150 mm², clamped cable lugs acc. to DIN 46234,
tightening torque 20Nm

4. Repair and maintenance
5.1 Maintenance
No maintenance is provided in addition to the regular checking of the contact sleeves
(unavoidable wear caused by high numbers of plugging cycles and by dirty or faulty
plugs).
5.2 Repair Attention:
The housing may not be opened when under voltage and only by
trained staff. Safety measure to DIN VDE 0105
Disconnect
Shield unit from restart
Verify disconnected parts are free of voltage
Ground an by-pass
Protect and separate the energised components near by.
Repair / reconditioning work may only be undertaken using WISKA
original spare parts. Changes or alterations to the equipment are not
permitted.
5.3 Replacement of the CEE-socket plug-in unit
Precautionary measures
Switch the entire equipment to the no-voltage state. Remove the cover
