3.3.3 Mounting instructions (size 3 and 4)
3.3.3.1 Free surrounding areas
With sizes 3 and 4 (41 to 200 A), a mounting clearance of 5 mm to the front
of the DS7 soft starter must be maintained. A top and bottom clearance of
75 mm each is required.
If the clearances are smaller, derating will be necessary or it will be
necessary to install an optional DS7-FAN-100 (for size 3) or DS7-FAN-200
(for size 4) device fan.
When combined with the NZM1 or NZM2 motor-protective circuit-breaker
and the NZM1/2-AB spacers, the minimum clearance
① between the DS7
soft starter and the NZM motor-protective circuit-breaker is:
• ≧ 25 mm at NZM1 (BG 3),
• ≧ 35 mm at NZM2 (BG 4).
The spacers ② are fitted underneath the NZM motor-protective circuit-
breakers and allow the required thermal air circulation for the heat sink of
the soft starter.
