3.2.8 Wiring of the plug systems
The plugs for connecting the temperature sensors and heating elements to a hot runner are
available on the rear of the controller. The customer-specific wiring plan for the plug systems
is located on the side of the controller housing (see Figure 6 for an example).

4 Commissioning
4.1
Electrical connection
Important! Before the device is connected to the supply voltage, a check must
first be performed to ensure that the mains electricity conditions comply with the
specifications on the type plate.
The electrical connections must be performed by a qualified electrician. Com-
missioning and operation while the controller is running are only to be carried
out by authorised qualified personnel!
Switching off all the outputs or individual zones will not protect any of the out-
puts against hazardous voltages. Before working on the connected heating
elements, the associated connections must be unplugged, or the entire device
disconnected from the mains power.
Before the device is opened, it must be disconnected from the mains power!
4.1.1 Mains power supply
Before connecting the device to the supply voltage, a check must be conducted to ensure
that the mains electricity system is correct. The hot runner controllers are prepared by default
for operation in a star network (3x N + PE) but can also be operated in a triangular
network (3x PE). For operation in a triangular network without a neutral conductor,
it is essential to follow the local regulations for the installation of electrical systems. The ter-
minals in the controller must be bridged accordingly for use in a star or triangular network.
Annex 11.1 contains a clear terminal connection diagram.
4.1.2 Mains connection
To ensure correct operation, the hot-runner controller is connected to the low-voltage mains
by using the connecting cable connected to the unit.
4.1.3 Connection of the mould
To connect the individual control zones to the corresponding injection mold, use must be
made of appropriate leads for the sensor and heating unit connection.
Please note: It must always be ensured that the internal wiring, the wiring of the
cable set and the wiring in the mold are suitably coordinated with each other.
Important! To exclude any effects of potential shifts, the injection molds that are
connected up must be properly earthed in all cases.
