during planning and set-up. The accessory has been designed
solely for operation on a 230 V/50 HzAC supply. Only qualied
electricians (to VDE 0100) are permitted to carry out work on the
230 V mains. Applicable accident prevention regulations must be
complied with whilst such work is being carried out. To avoid electric
shocks from the accessory, please disconnect the mains voltage
(trip the miniature circuit-breaker). Noncompliance with the
installationinstructionscancausereorintroduceotherhazards.
When connecting to the terminals, take the permissible cables and
cable cross sections into account.
Take the technical data (in particular the maximum permissible
e󰀨ectiveinstalledloadoftheaccessoryandthetypeofloadtobe
connected) into account before connecting a load! All load data
relatestoohmicloads.Donotexceedthecapacityspeciedforthe
accessory.
The accessory has not been designed to support safety
disconnection.
Exceeding the maximum capacity could lead to the destruction of
theaccessory,resorelectricshocks.
Before the accessory is connected, remove the fuse from the fuse
box.

Hazard information
Observe the installation instructions for installation in distribution
systems (DIN VDE 0100-410).
The control voltage of the 0 to 10 V output is electrically isolated
from the mains potential but is not at safety extra-low voltage
(SELV). This must be observed during cable routing, installation
and connection.
The accessory may only be operated within residential buildings.
Using the accessory for any purpose other than that described in
this operating manual does not fall within the scope of intended use
and shall invalidate any warranty or liability.

Safeguard from switching on again; Check that system is
de-energised; Earth and short circuit; Cover or cordon o󰀨
neighbouring live parts;
• Select suitable tools, measuring equipment and, if necessary,
personal safety equipment;
• Evaluation of measuring results;
• Selection of electrical installation material for safeguarding
shut-o󰀨conditions;

Start-up
and the resulting connecting conditions (classical zero
balancing, protective earthing, required additional measures
etc.).
For installing the DHC Multi IO Box into a power distribution panel,
it has to be mounted in accordance with VDE 0603, DIN 43871
(low-voltage sub-distribution board), DIN 18015-x. In this case, the
installation must be made on a mounting rail (DIN rail) according to
EN50022. Installation and wiring have to be performed according
to VDE 0100 (VDE 0100-410, VDE 0100-510 etc.). Make sure to
consider the technical connection requirements (TAB) of your
energy supplier.
The circuit to which the accessory and the load will be connected
has to be secured by a cable protection switch in accordance with
EN60898-1 (tripping characteristic B or C, max. 16 A rated current,
min. 6 kA interrupting rating, energy limiting class 3). Installation
regulations according to VDE 0100 and HD382 or 60364 have to
be considered. Users must be able to easily access the cable
protection switch. This must be marked as disconnecting device for
the actuator.
Observe the hazard information in „2 Hazard information“ on page
8 during installation.
