4. Commissioning
4.1. Mechanical mounting
The gateway housing is designed for DIN rail mounting. Use a small screw driver to open the housing
and pull out the gateway halfway until stop for setting of Node ID, baud rate and terminating resistor.
• Grid 22.5 mm, height approx. 100 mm and depth approx. 110 mm
• For mounting on 35 mm DIN rail
For mounting on DIN rail place the gateway rear onto the rail and press down until lock snaps into
place.
4.2. Electrical connection
4.2.1. Electrical commissioning
• Do not perform any electrical modifications at the gateway.
• Do not carry out any wiring work when the gateway is live.
• Ensure that the entire equipment is installed in line with EMC requirements. Both ambient
installations and wiring have an impact on the electromagnetic compatibility of the gateway. Install
the gateway and supply cables separately or remote from cables with high interference emissions
(frequency converters, contactors etc).
• When working with consumers with high interference emission provide separate power supply for
the gateway.
• Connect gateway to protective earth (PE) conductor using shielded cables. The braided shield must
be connected to the cable gland or plug. Ideally, aim at bilateral connection to protective earth (PE),
i.e. the housing via the mechanical assembly and the cable shield via the downstream devices. In
case of earth loop problems earth on one side only as a minimum requirement.
Failure to observe these instructions can result in malfunctions, material damage or personal injury.
4.2.2. Supply voltage connection
Supply voltage connection of gateway and SPA is provided by screw terminals 5 (GNDB) and 6 (UB)
or by screw terminals 7 (GNDB) and 8 (UB). Terminals 5 and 7 as well as 6 and 8 are internally
connected providing a loop for power supply to further consumers (for example the spindle position
display SPA).
4.2.3. Shield connection / functional earth
Protective earth may be assigned to terminal 1 that at the same time provides shield connection of the
RS485 bus. There is a link to terminal 1 and to the housing of the 9-pin SUB-D connector (CANopen).
Additional connection to protective earth is via DIN rail mounting. For this purpose the DIN rail must be
connected to functional earth by low-impedance.
