Mounting Instructions - Power Assembly

All MVS models are rated IP00 and must be installed inside an enclosure.
No clearance is required below or at the sides. The power assembly should be installed with 100 mm clearance above
for isolation.
NOTE
Models with current ratings 500 A and above require forced air ventilation when installed in an enclosure.
Mounting Points
The power assembly is mounted in place using four M12 bolts. One bolt is required through each corner at the base of
the unit, tightened to a torque of 40 Nm. Individual phase arms are secured within the frame using one M10 nut and two
M10 high tensile grade 8.8 bolts complete with Belleville washers, all tightened to a torque of 28 ~ 30 Nm.
