1. Safety
1.1 Important safety instructions ! ! !
1. The operating instructions must be read carefully and the safety, warning and hazard in-
formation must be observed.
2. Functional impairment of pacemakers and other medical aids.
1.2 Intended use
The POWER2CAR STEEL wallbox is used for charging electric vehicles in accordance with IEC 62196.
The product can be mounted directly on a wall or operated as a free-standing charging pole using the
optional stand available from the manufacturer. The POWER2CAR STEEL wallbox has a permanently
connected charging cable with a type 2 plug that must be plugged directly into the charging device of
the electric vehicle.
1.3 Reasonably foreseeable misapplications
The unit is to be used exclusively for the task and environment described in the operating instructions.
Lack of maintenance, incorrect or improper use or unauthorised modification can lead to destruction or
malfunction. The manufacturer is not liable for any damage resulting from this and the warranty expires.
The risk for this is borne solely by the operator.
1.4 Designs of the charging station and documentation
There are also different documents for the respective versions, which can be downloaded from the In-
ternet as PDF files at www.renz.com.
POWER2CAR STEEL Wallbox can be used outdoors and in covered areas and is described in these
instructions. Various accessories are available for this, e.g. a stand.
POWER2CAR CITY Wallbox corresponds to the POWER2CAR STEEL Wallbox, but the screw-on hou-
sing and the cable holder are powder-coated.
POWER2CAR FUEL Wallbox may only be used in a covered area; separate instructions have been
prepared for this purpose.

1.5 Installation, maintenance and servicing
Work on the unit may only be carried out by persons who are familiar with it, have been informed about
the dangers and have the necessary qualifications. In particular, the generally applicable safety and
accident prevention regulations must be observed.
The electrical connection may only be carried out by a qualified electrician in accordance with DIN VDE
0100! In particular, the local protective measures as well as the valid VDE and EN regulations and, in
the public sector, also the DGUV regulations must be observed! The corresponding safety checks must
be carried out and recorded.
The commissioning of a charging station may require a permit from the responsible grid operator!
Work on the unit is only permitted when it is de-energised (mains disconnection).
1.6 Charging cable
The charging cable may only be unplugged by pulling the plug (not the cable)!
The charging cable must not be extended!
Protect the plug from dirt and moisture!
The cable must not be bent, pinched or run over!
After charging, the charging cable must be loosely wrapped around the charging station again.
The protective cap of the plug is to be properly pushed back onto the plug after charging.
1.7 Wire cross-section
When selecting the cross-section of current-carrying conductors, both the upstream protection and the
voltage drop due to long cable lengths must be taken into account.
1.8 Liability
The function of the unit depends on many influencing variables over which the manufacturer has no
control. The manufacturer cannot guarantee the functional reliability of the unit. No liability is accepted
for consequential damage.
2. Disposal
If the charging station is finally taken out of service, the individual components must be disposed of
properly at a recycling facility.

3. Structure and type plate
3.1 General structure
Figure 1
The POWER2CAR STEEL Wallbox charging station is composed of various sheet metal parts and two
plastic housings that contain the electrical components. Together, they form a robust, beautifully sha-
ped charging station.
3.2 Position of the type plate
1. Position of the type plate

This illustration shows the position of the type plate. In case of questions with the technical support, the
most important data for the assignment of the charging station can be read here.

4. Installation
4.1 Placement and surroundings of the charging station
If the charging station POWER2CAR STEEL Wallbox is operated without a stand, the device must be
mounted on a stable wall. The position should be selected so that the wallbox is operated free from
negative weather influences (no direct sunlight and free from rain).
When mounting the charging station on the wall, a height of 0.9 m from the floor to the lower edge
should be maintained.
Furthermore, when selecting the position, it must be taken into account that the charging station can be
operated directly with the charging connection of the vehicle without additional cable extensions and
that no tripping hazards or similar are formed by the unrolled charging cable.
4.2 Attachment
Figure 3
The unit has a stainless steel wall housing with which the unit is fixed to the wall. The unit is fixed to the
wall by means of the 4 fixing holes in the wall casing using 12 mm dowels and 10 mm hexagonal wood
screws.
Dowels and screws are included in the scope of delivery of the unit

4.3 Connection or supply line
The connection cable and the corresponding fuse protection must be determined according to the desi-
red charging current, the cable type, the cable lengths and the local and standardised regulations.
Charging
current

Fuse protection
[A] Typ B Minimum cross section
[mm²]
10 16 5 x 2,5
16 16 5 x 2,5
Each charging point must be equipped with a separate fuse.
Table 1
4.4 Residual current circuit breaker
The circuit must be protected by a type A residual current device (RCD) with a tripping current of 30
mA. e.g. ABB F204 A-40/0,03
This residual current circuit breaker must be installed in the house distribution before the supply line to
the POWER2CAR STEEL Wallbox charging station. Each charging point must be equipped with a se-
parate residual current circuit breaker.
The charging electronics in the vehicle can generate a DC residual current which is not detected by the
type A residual current circuit breaker. To protect against these DC residual currents, the POWER2CAR
STEEL wallbox has an integrated DC monitor. This component detects the residual currents and, in the
event of a fault, triggers the residual current circuit breaker in the house distribution. This means that no
universal current-sensitive residual current circuit breaker (type B) is required.
Info: Some vehicles (e.g. Renault Zoe) generate such a high fault current during the charging process
that the RCD installed in the distribution system trips sporadically.
The following residual current circuit breakers are immune to these spikes and have proven themselves
in practice:

FS453M

DFS 4 xxx/0,03-EV

4.5 Checking the residual current device
Figure 5
The DC monitor integrated in the POWER2CAR STEEL wallbox has a test button for checking the resi-
dual current device. When pressed, a 6 mA DC residual current is generated. The DC monitor then
generates an AC residual current which triggers the residual current circuit breaker in the house distri-
bution system.
This function must be checked when the unit is put into operation and later once a year.

4.7 Release contact
At the factory, the POWER2CAR STEEL wallbox is equipped with a wire jumper between "+" and "IN"
of the terminal strip (table 3 no. 2) of the charge controller. On the customer side, this connection can
be used for an external charging release. In this case, an external potential-free contact controls the
charging release (e.g. separate key switch, ripple control receiver or similar).

turer's instructions. Authentication by the user is not performed. The charging station can be switched
on or off by switching the fuse on/off.
5.3.2 End charging process
1. The charging process is terminated by the vehicle. (Multi-colour LED: OFF).
2. The charging plug must be removed from the vehicle and the protective cap must be pushed
onto the charging plug.
3. The charging cable must be rolled up around the POWER2CAR STEEL Wallbox charging stati-
on.
Info: For details on how to end the charging process on the vehicle, please refer to the vehicle manu-
facturer's instructions.
6. Maintenance
6.1 Annual
Checking the residual current device by pressing the test button on the DC monitor.
Checking the charging cable and charging plug for mechanical defects.
Checking the operation of the multi-colour LED.
Danger: If the charging station is operated in public areas, additional maintenance must be car-
ried out in accordance with the DGUV regulations!
Danger: Defective or damaged components must be replaced immediately!

10.2 Cable holder
The cable holder is used to store the charging cable more gently. The charging cable is hung loosely in
the wall holder with a radius as large as possible.
This cable holder can be attached directly to the base of the wallbox or to a stable wall next to the wall-
box.
