Installation and power supply connection
The electrical installation of the eMH1 Wallbox model variants described in this manual
must always be carried out by qualified specialist personnel: Please contact an electri-
cal contractor or arrange installation at your premises with your local distributor.
However, as a user you may carry out the mechanical installation of the wallbox your-
self, as long as you follow the safety notices and general instructions.
Prerequisites for the mounting site and installation
Your eMH1 Wallbox is an electrical device and is therefore subject to particular prereq-
uisites for indoor and outdoor installation: Although the housing of the eMH1 complies
with the standards for the IP54 degree of protection, you must take into account cer-
tain environmental conditions, especially outdoors.
In selecting the mounting site you must consider the following points:
• For the safe operation of your wallbox, minimum distances to other technical instal-
lations must be observed: You can obtain further information from your electrical
contractor or your distributor.
• The wallbox must be installed where it is freely accessible to all authorized users.
• Ideally, the mounting site should already provide connection to the power supply. If
not, a separate supply must be installed that complies with the generally prescribed
standards for cabling and building infrastructure: Please contact a qualified electrical
contractor for details.
CAUTION!
The power supply for the eMH1 must always be protected by a separate
domestic miniature circuit breaker (MCB)
Some model variants may require the supply cable to be protected by an
additional external FI residual current circuit breaker (RCCB). Further infor-
mation available under Technical Data, see page 20.
• Depending on model variant, this wallbox is designed for connection to and opera-
tion on a rated voltage of 230/ 400 V 50 Hz.
• The power supply cables may be installed above or below the wall surface. How-
ever, the cable should preferably enter the device through the inlet on the underside
of the bottom part of the housing.
• Sufficient air circulation must be ensured at the installation site so that the wallbox
is cooled during operation: Always observe the allowed operating temperatures (see
“Technical specifications” on page 20).
• Do not install or operate the wallbox in direct sunlight, as it could overheat and/or the
housing could be damaged over time.
