Electrical Connection; Mains Supply - Fluke VIBGUARD IIoT Installation And Operation Manual

Installation and Operation

7 Electrical connection

VIBGUARD IIoT is wired with the supply components at the factory. The following connections are to be established
for installation on site:
Connection to the mains supply
Connection to the data network (Ethernet)
Connection to the sensor lines and to the digital inputs and outputs
Connection to machine control / PLC via Modbus RTU
Installation description for the variant in the protective housing
The following installation steps illustrate installation for the variant in the protective housing. The connec-
tions for the variant in the switch cabinet (VIB 7.xxx-PS) are to be established in the same way.

7.1 Mains supply

CAUTION
Risk of injury due to electric shock!
Components may be live if not properly connected to the mains supply.
Only an electrical specialist is allowed to connect the mains supply.
The mains supply must comply with IEC guidelines.
Before carrying out any installation, repair or maintenance work, disconnect the system from the power
supply, determine that there is no voltage and secure the power supply against being switched on again.
The protective earthing is carried out via the mains connection cable. The PE bolt on the bottom side of the hou-
sing is used to increase the cross-section of components for overvoltage discharge.
Connect the PE bolt (1) on the bottom side of the housing over a short distance with PE at the site of instal-
l
lation (cross section: 2.5 - 16 mm²)..
Open the M20 cable gland (2) for the supply line with a suitable spanner (size 24) and remove the sealing
l
insert.
Place a cable loop in order to not put any strain on the connection during subsequent service work.
l
Guide the supply line through the cable gland (clamping range 7 - 13 mm). The conductor cross section must
l
be at least 1.5 mm².
