Where possible, minimize the wire length between the regen and the
drive. The wire length should not exceed 10 feet.
Avoid routing and bundling the regen AC/DC wire with the drive AC PWM
motor output wiring.
3.4.1.1. 3-PHASE AC INPUT
Do not install chokes or reactors between the regen and the power source
besides the M3645-x300R. If the AC drive requires a line reactor, the
regen should be connected to the utility grid side.
If an isolation transformer is to be used, the regen AC input MUST be
connected to the same point as the drive AC input. The transformer
should meet the ratings shown in Table 3-1.
Table 3-1: Transformer Ratings
Do not connect to a generator. For further details, contact Bonitron.
The regen units are not phase sensitive.
The AC line connections should have short-circuit current protection.
Recommended fuses are listed in Section 6.5.
3.4.1.2. INTER-MODULE WIRING FOR 300A ONLY
For M3645 rated for 300A an individual line reactor must be used in
front of each M3645-x300T transistor module. See Figure 3-10 for
wiring diagram.
The user must wire both the control AC wiring from the M3645-x300R
line reactor to the M3645-x300T transistor module.
The control wiring must be connected to the utility side of the M3645-
x300R and is phase sensitive.
