Connecting the power supply of the Spector control
The SPECTOR control belongs to protection class 3. The unit is supplied with 24 V DC SELV (Safety Extra
Low Voltage). Remember to take the maximum breaking capacity of the fuse into consideration. The
power supply is not galvanically isolated. The 0V connection is directly at the housing potential. Produce
the connection as follows:
■
The supply cable must have a cross-section of 0.75 mm² minimum and 2.5 mm² maximum.
■
A flexible lead or wire can be used for connection.
■
Remember to take the power consumption into consideration.
■
The use of a functional earth can prevent interference due to differences in potential.
The cross-section must not exceed 2.5 mm 2 .
■
The GND is connected directly to the housing potential.
The connector (female header with screw terminals) for connection is included in the product package
(WAGO 1757022).

Supply voltage connection
The SPECTOR control unit, CANopen devices and WAGO I/O module 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 reliable electri-
cal isolation.
This power supply unit must be electrically isolated from dangerous live voltages and meet the require-
ments for double or reinforced insulation in accordance with one of the following standards:
DIN EN 50178, DIN EN 61010-1, DIN EN 60730-1 or DIN EN 60950.
Attention
■
Do not use the bus power supply for GESTRA SPECTOR bus control units for supplying
power to the SPECTOR control or connected equipment.
Attention
■
In the event of reverse polarity and simultaneous connection
of another 0V connection, e.g. GND of the COM1 port, the fault
current flows via this 0V connection. If the housing is also not
connected securely to the 0V potential, the Ethernet panel or
external components may suffer irreparable damage!
■
For a safe connection, make sure the two connecting cables are
joined close to the connector.
