INSTALLATION
2.7.2 Easidew PRO XP EX2 (Display)
NOTE: To ensure compliance with EMC standards, ensure that the screen of the
power supply/signal cable or the power supply/signal conduit is connected
to ground.
With the cable entry option, a conductive cable entry gland is recommended,
allowing the transmitter housing to be earthed via the cable screen connection.
Always connect the 4-20 mA return signal to a suitable load
(see Figure 16) before the power is applied. Without this
connection, the transmitter may be damaged if allowed to
operate for prolonged periods.
