3.2 Electrical Installation
DANGER
The instrument must be installed
by qualified technical personnel
for adherence to all applicable
electrical codes.

High-voltage wiring for the controller is conducted behind the high voltage barrier

in the controller enclosure. The barrier must remain in place unless a qualified

installation technician is installing wiring for power, alarms, or relays. See Figure

3-11 for barrier removal information.

3.2.1 Installation in ConduitIn hard-wired electrical applications, the power and safety ground service drops

for the instrument must be 18 to 12 AWG. See Figure 3-12 on page 12 for strain

relief and conduit opening sealing plug information. See section 3.2.3 on page 12

for wiring information.

3.2.2 Installation Using a Power Cord

A sealing-type strain relief to maintain the NEMA 4X/IP66 environmental rating

and a power cord less than 3 meters (10 feet) in length with three 18-gauge

conductors (including a safety ground wire) can be used, see Replacement Parts

on page 21. See Figure 3-12 on page 12 for strain relief and conduit opening

sealing plug assembly. See section 3.2.3 on page 12 for wiring information.
