Wiring the Inverter

WARNING! 

Ensure that all wiring is electrically isolated and cannot be made “live”

unintentionally by other personnel.

Note:  Refer to Chapter 11: “Technical Specifications” for additional Cabling Requirements and

Terminal Block Wire Sizes.

Figure 3-4  Cabling Requirements

Cables are considered to be electrically sensitive, clean or noisy. You should already have

planned your cable routes with respect to segregating these cables for EMC compliance.

If not, refer to Chapter 12: “Certification for the Inverter”.

Cable Gland Requirements

Use a metal gland to connect to the internally earthed gland plate. It must be capable of securing

a 360 degree screened connection to give EMC compliance. A 360 degree screened connection

can be achieved as shown.

The receiving hole in the gland plate has a compromised diameter of 28.6mm to accept metric

M20, PG16 and American ½” NPT cable gland sizes.
