Quick Start Guide

7 Prepare the electrical connections
7.1 Cable selection
Use 24-16 AWG wire (0.20-1.5 mm
2
). Twisted pairs and shielded wiring are
recommended for environments with high EMI (electromagnetic
interference).
Fine stranded conductors shall be equipped with a ferrule.
7.2 Cable gland/conduit
For explosion-proof/flameproof installations, only use cable glands or
conduit entry devices certified explosion-proof or flameproof.
7.3 Internal power consumption
< 0.8 W in normal operation
7.4 Grounding
Make sure grounding is done according to national and local electrical
codes. Failure to do so may impair the protection provided by the
equipment.
Transmitter housing
The most effective grounding method is direct connection to earth ground
with minimal impedance. There are two grounding screw connections
provided (see Figure 7-1).
