Connecting the power supply for Spector control
SPECTOR control belongs to protection class 3. The system power supply must be provided with 24VDC
SELV (safety extra-low voltage). The max. disconnection capacity of the fuse must be taken into consider-
ation. The power supply is NOT isolated. The 0 V connection is directly connected to the housing potential.
The voltage supply is protected with a melting fuse. A reverse polarity protective device is used to protect
the equipment in the event of reversed poles. Operation, however, is only possible if the connection was
made correctly.
The connection must be made as follows:
n
The cross section of the power supply cable must be at least 0.75 mm² and a maximum of 2.5 mm².
n
A flexible lead or wire can be used for the connection.
n
The current consumption must be taken into account when implementing the power supply.
n
The functional earth can help to avoid disturbance caused by potential differences.
The cross section must not be less than 2.5mm
2
.
n
The GND connection is directly connected to the housing potential.
For safety reasons the wires should be fixed together near by the connector.
The plug connector (socket connector with screw terminals) for the power supply connection is supplied
with the equipment. (WAGO 1757022).

Connecting the power supply
SPECTOR control , all CANopen devices and the WAGO IO terminal block are supplied with 24 V DC /
≥ 5 A. 5 A is the sum current of all CAN bus nodes. Please use a safety power supply unit with safe
electrical isolation.
The power supply unit must be electrically isolated from dangerous contact voltages and must meet at
least the requirements on double or reinforced isolation according to one of the following standards:
DIN EN 50178, DIN EN 61010-1, DIN EN 60730-1 or DIN EN 60950.
Attention
n
Do NOT use the power supply of GESTRA control devices for the power supply of
SPECTOR control and connected equipment.
Attention
n
In the event of reverse connection and simultaneous connection
of a further 0 connection, e. g. GND connection of the COM1
interface, the fault current flows via this 0 V connection. If the
housing is not lying well set on the 0 V potential, the result can
be destruction of the equipment or of external components!
n
For safety reasons the wires should be fixed together near by the
connector.
