Battery power One 3 V button cell lithium battery (BR2032 or CR2032) required to power real-time

clock when device is powered off.

Note 7: The LGR-5325 AGND and GND pins are tied together internally. These grounds are electrically

isolated from the EGND (earth ground) pin.

The LGR-5327 AGND, GND and ENC- pins are tied together internally. These grounds are

electrically isolated from the EGND (earth ground) pin.

The LGR-5329 AGND, GND and ENC– pins are tied together internally. These grounds are

electrically isolated from the EGND (earth ground) and the IGND (isolated ground) pins.

Chassis ground

Table 15. Chassis ground specifications

Parameter Specification

Number of inputs Single terminal EGND (pin 80)

Isolation method 10 nF/1000 V ceramic capacitor in parallel with 1 MΩ resistor

Note 8: The EGND pin is isolated from the measurement and I/O circuits. Only use the EGND pin to connect a

LGR-5320 Series device to a local chassis ground connection. Do not use the EGND pin as a return

path for any of the analog or digital I/O.
