Chapter 2 MOUNTING AND WIRING
2.1 Mounting the dynamic breaking unit
(1) Installation
environment
Mount the dynamic breaking unit at the place satisfying the requirements given in Chapter 1, Section 1.3.1 "Installation
environment."
(2) Mounting
base
Install the dynamic breaking unit on a base made of metal or other non-flammable material. Do not mount the dynamic
breaking unit upside down or horizontally.
Install the dynamic breaking unit on a base made of metal or other non-flammable material.
Otherwise, a fire could occur.
(3) Clearances
Mount the dynamic braking unit only in the direction shown in Figure 2.1-1 (in the reading direction of the nameplate). For
the clearances, refer to Figure 2.1-1 and Table 2.1-1. When mounting two or more dynamic braking units side by side,
observe also the clearances specified in Table 2.1-1.

- Dynamic braking units cannot be mounted, one above the other.
- Above the dynamic braking unit (i.e. above the exhaust fans) at location "C," only a DC fuse (authorized by Fuji)
can be mounted. To mount general devices, select devices whose maximum allowable working temperature is
70
C and prevent them from interfering with the effect of the exhaust fans.
- Beneath the dynamic braking unit (i.e. beneath the intake vent) at location "D," do not block about 60% of the
area in the 350 mm clearance. When mounting a device, ensure a 100 mm clearance.
