How to install

1. Electrical connections

The GT7 terminal is connected to a network via a LAN interface, this configuration is used for configuration and communication during operation. Power can be supplied via a separate power supply or via Power over Ethernet (PoE). We strongly recommend using a separate power supply.

Network Connection (LAN / Ethernet)

...

Recommended cabling/cable lengths for LAN Ethernet:

• Shielded and twisted data cable (recommended min. CAT5 for 100MBit)

• Supply voltage via 2 wire pairs (PoE)

• Cable length max. 100m

Depending on the Ethernet standard being used, terminate the wire colors as follows:

1.2 Digital inputs and outputs

...

Relay outputs

The 2 relay outputs “Rel. 1” and “Rel. 2” can be used to output digital signals to control external components such as electrical door locks. Both relay outputs are normally open contacts (NO).
(GT7.2x00 has only one relay input, and GT7.3x00 terminals have two.)

Optocoupler inputs

Digital signals can be acquired with 1 input.

The “Opto” input is a potential-free input, i.e., a voltage and ground (GND) must be applied. The voltage or GND can be used from the terminals “VOut” on the GT7 terminal (see example).
The voltage must not exceed max. DC +30 V.

1.4 Power supply connection

...

There are 2 options for supplying power to the GT7 terminal:

1. Via a separate power supply.

2. Via Power over Ethernet (PoE).

For PoE, consider the following requirements:

• Must comply with IEEE 802.3af

• Power class: 0

• Min. 15.4W per PoE port

Please note that some PoE switches do not transmit the power voltage on separate wires (DC+ and DC-) but superimpose it on the transmit and receive lines (RX+/- and TX+/-). In this second case, the GT7 terminal is supplied with voltage even if only RX and TX are connected.

Depending on the Ethernet standard being used, terminate the wire colors of the Ethernet cable to the “ETHERNET PoE” screw terminals as follows:
