It is good practice to protect motors by fitting temperature
sensitive resistors. A typical resistance (up to a reference
temperature of 125
C) is 200
, rising rapidly to 2000
above
this temperature. Connect devices in series between TH1A and
TH1B. Link the terminals if temperature sensors are not used.

Terminal
Supply protective earth (PE). This terminal must be connected to a protective (earth)
ground for permanent earthing.

Terminal Block Acceptance Sizes
Wire sizes for Europe should be chosen with respect to the operating conditions and your local National
Electrical Safety Installation Requirements. Local wiring regulations always take precedence. For North
American UL wire sizes refer to Chapter 10: “Certification for the Drive” - Requirements for UL
Compliance.

available to enable wiring with flat busbar, part number BE465483.
* The larger wire sizes can be used provided a crimp is fitted to the wire
