Terminal Block Acceptance Sizes
Wire sizes should be chosen with respect to the operating conditions and your local National
Electrical Safety Installation Requirements. Local wiring regulations always take precedence.

Power Wiring
Note: For specified EMC emission and immunity performance, install to EMC Installation
Instructions. Refer to Chapter 10: “Certification for the Drive” - for more information
Terminal tightening torque for Frame 3 power connections is 20 lb.in (2.26Nm).
Protect the incoming mains supply using the specified fuse, or RCD circuit breaker Type B.
IMPORTANT: We do not recommend the use of circuit breakers (e.g. RCD, ELCB, GFCI), however,
where their use is mandatory, they must:
• Operate correctly with dc and ac protective earth currents (i.e. type B RCDs as in
Amendment 2 of IEC755).
• Have adjustable trip amplitude and time characteristics to prevent nuisance tripping
on switch-on.
Control Wiring
Control wiring of between 0.08mm
2
(28AWG) and 2.5mm
2
(12AWG) can be used. Ensure all
wiring is rated for the highest system voltage. All control terminals are SELV (Safe Extra Low
Voltage), i.e. double-insulated from power circuits.
Using Cage Clamp Terminals
Strip the wire insulation to 5-6mm (0.20-0.24 inches), or
alternatively use wire-crimps. Insert a flat-bladed screwdriver,
maximum blade size 3.5mm. The cage provides the correct
force for a secure connection.
IMPORTANT: DO NOT lever or turn the screwdriver.
