SMARTCONTROL IP 65 Power Supply
The power supply cable may have no more than 3 conductors with a maximum cross-section of 4 square mm
each, and must be led in through the heavy duty cable gland at the bottom of the housing. This cable must be
connected to the 230 V AC terminal block (see below): N, PE and L1.

230 V AC supply power is fed via a circuit breaker (B6A) to the power pack (F1).
The SMARTCONTROL can be supplied with 12/24 V DC. The power pack is supplied with a standard output of
24 V DC, or with 12 V DC as an option. It’s also possible to install both power packs. If applicable, 24 V DC is
required for additional components such as an M-Bus level converter, and 12 V DC is required for certain sensors.
The SMARTCONTROL PCB is supplied with electrical power via the connector terminal [see “Connections
Overview,” in section 6. as of item 20].

Low-Current Leads
5.6.1.
SMARTCONTROL IP 65
The leads are fed through the heavy duty cable glands at the bottom of the housing.
Note:
Tighten the threaded cable glands to the specified tightening torque. The housing must be water-
proof. If necessary, the included connectors must be replaced with more suitable ones, and
unused connectors must be replaced with blanking plugs. It must be assured that only
standardized materials which are suitable for the IP 65 standard and which seal the openings
appropriately are utilized.
The shields of all shielded cables must be connected to a ground bus bar by means of shield terminals assuring
large surface-area connection. Identify all cables which are fed into the housing with the respective cable number
in accordance with the wiring diagram in a readily legible fashion using cable ties. Secure the cables firmly, with
cable ties if necessary.

SMARTCONTROL Standard
Warning:
Cables must be voltage-free.
Note:
The cables must be led in from the bottom and secured by
means of heavy duty cable glands.
It must be assured that the cables are long enough to reach the
connector terminals.
