2.5.1 Unit Installation (fig. 3-6)
•
Press the air inlet grille (6) down slightly on both sides, tip forward at the front and remove.
Unscrew both screws at the air outlet grille (5) and remove the grille (fig. 3).
•
Loosen the front wall (4) with 2 screws at the bottom (inside threaded holes), lift the front wall
slightly and remove (fig. 4). Loosen the inside front wall with 2 screws at the bottom and remove
(fig. 5).
•
Disassembly of the right side wall (3): Remove the rotary knob (a), screw (b) on the side wall (3),
pull the side wall slightly to the side at the back (c), push forward, tilt to the side at the top (d),
lift and remove (fig. 6).
•
Feed the power cables and connecting cables for charging control unit and discharge control
unit through the opening in the unit rear wall (15) and connect according to section 2.5.2 (lay
connecting cable about 210 mm and shorten as required so that it does not obstruct the air
vents in the side wall);
•
Place the unit at the planned location and screw to the wall (or to the floor if floor fixing is
necessary).
•
Remove cover plate (10), cardboard inlays and operating button from inside (fig. 9). This must be
completely free of foreign bodies such as packing leftovers.
Check the thermal insulation in the unit for transportation damage and replace if necessary.
Insert the storage blocks (fig. 10 and 11)
The storage blocks are delivered packed separately.
Storage blocks with slight transportation damage may still be used. This does not impair the
function of the heater.
The heating elements (17) must be lifted slightly to insert the storage blocks (9) (fig. 10).
Place the first storage block with the heating element recess at the top some distance away from
the right thermal insulation under the heater and push to the right and rear thermal insulation.
The elongated holes form the heating channels.
When lifting the heating elements, make sure that the through holes in the side thermal insulation
are not widened by the heating elements.
Then push the cover plate (10) removed from the interior over the top storage blocks (fig. 12).
2.5.2 Electrical Connection
The heating elements are connected electrically with 3/N/PE ~ 50 Hz 400 V or in the
units WSP 2010 also with 1/N/PE ~ 50 Hz 230 V.
Direct connection with NYM is possible. The number of supply cables and wires as well as cable
cross sections depends on the connection rating of the unit and the type of mains connection and
on special electricity supply company regulations. Observe the appropriate circuit diagrams for
this.
When connecting the unit to an automatic charging control unit, voltages may occur at the
terminals A1/Z1 and A2/Z2 even when the fuses are removed.
Connection
Relieve the strain on the electrical connecting leads as required and connect according to the
electrical circuit diagram in the device (on the inside of the right side panel) or the connection
diagram.
If the bracket in the switching area for holding the mains terminals is poorly accessible due to too
small a spacing, it can be swung forward during connection work after loosening the screw (not
removing) in the rear panel.
