This chapter contains installation instructions and examples.
Checking the installation site
The brake chopper module must be installed in an upright position. The degree of
protection of the module is IP00. Take this into account when selecting the installation site.
Installation in a cabinet is highly recommended.
Obey the general ACS880 multidrive module cabinet installation instructions given in
Cabinet design and construction instructions for ACS880 multidrive modules
(3AUA0000107668 [English]). In addition, observe these restrictions:
•
The brake unit can be grounded to the frame through the mounting screws if the
galvanic connection to PE (protective earth) is good enough.
•
Leave 150 mm (5.91 in.) free space below and above the brake chopper module.
•
Leave enough space for the fuses and the cooling fan.
•
To prevent the module from overheating, do not install it directly above the brake
resistors.
The maximum lengths of the chopper and resistor cables are 5 m and 10 m, respectively.
Required tools
Make sure that you have these tools available:
•
drill with suitable bits
•
screwdriver and/or wrench with a set of suitable bits
