2.
Connect the inverter and its components.
The plugs for connecting the line supply,
motor, and braking resistor can be found on

Components for United States / Canadian installations (UL/CSA)
This equipment is capable of providing internal motor overload protection according to
UL508C. Take the following actions In order to comply with UL508C:
● Use UL/CSA-certified J-type fuses, overload circuit-breakers or intrinsically safe motor
protection devices.
● For each frame size A to C use class 1 75° C copper wire only.
● Install the converter with any external recommended suppressor with the following
features:
– Surge-protective devices; device shall be a Listed Surge-protective device (Category
code VZCA and VZCA7).
– Rated nominal voltage 480/277 V
AC
, 50/60 Hz, 3-phase.
– Clamping voltage V
PR
= 2000 V, I
N
= 3 kA min, MCOV = 508 V
AC
, SCCR = 40 kA.
– Suitable for Type 1 or Type 2 SPD application.
– Clamping shall be provided between phases and also between phase and ground.
● Do not change the parameter p0610 (factory setting of p0610 = 12 means: the drive
reacts on a motor overtemperature with an immediate alarm and after a certain time with
a fault).
