4. Commissioning
4.1. Scope of delivery
• Gateway
• Two screw terminals
• Strain relief/shield connection terminal
• Data carrier with GSD file
• Manual
4.2. Mechanical Mounting
The gateway features a small housing for DIN rail mounting. It can easily be opened by screwdriver and
pulled out partially in order to set the bus node ID and bus termination.
• Width of pattern 22.5 mm, height approx. 100 mm and depth approx. 110 mm
• For mounting onto 35 mm DIN rails
For mounting onto the DIN rail, the gateway is inserted from rear into the DIN rail and then pressed
down to lock.
4.3. Electrical connection
4.3.1. Electrical commissioning
• Do not carry out any electrical modifications at the gateway.
• Ensure that the entire equipment is installed in line with EMC requirements. Ambient installation and
wiring affect the electromagnetic compatibility of the gateway. Install gateway and supply cables in
separate rooms or far away from cables with high interference emission (frequency converters,
protections, etc.
• Provide a separate supply voltage for the gateway where working with consumers with high interference
emission.
• Connect the gateway to protective earth (PE) conductor using shielded cable. The braided shield must
be connected to cable gland or plug. Ideally, aim at a bilateral connection to protective earth (PE), i.e.
housing via mechanical assembly and cable shield via downstream devices. In case of earth loop
problems, earth on one side only as a minimum requirement.
Failure to observe these instructions may result in malfunctions, material damage or personal injury.
4.3.2. Supply voltage connection
Supply voltage connection for gateway and SPA by pin 5 (GNDB) and 6 (UB) or by pin 7 (GNDB) and
8 (UB). Pin 5 and 7 as well as 6 and 8 are internally connected with each other for looping the
operating voltage down to other consumers (for example to SPA).
UB: 12...24 VDC, ripple less than 5 %, 200 mA.
In addition, each spindle position display (without motive drive) is consuming approx. 30 mA. For
specific data of the SPA power consumption please refer to the respective data sheet.
4.3.3. Shield connection / functional earth
Connection of protective earth to pin 1 which is at the same time serving for connecting the RS485
bus shield. There is a connection between pin 1 and the housing of the 9-pin D-Sub connector
(Profibus). The PE (protective earth) connection is additionally carried out by the DIN rail mounting.
For this intention the DIN rail has to be connected to functional earth by low-impedance.
