Electrical Connections
Control Connections
The rectifier control terminals are mounted at the top of the front face of the Rectifier module.
See Figure 2–7. The customer terminals are the left half of a 10-pin plug and socket, referenced TB1, and may
be unplugged for ease of wiring. See Figure 2–8
for the terminal layouts and functions.
Figure 2–8. – Rectifier Module Control Terminals At TB1
Terminals will accept up to 2.5 mm
2
(12 AWG) flexible cables. To prevent failure of the Rectifier module pre-
charge components, the rectifier pre-charge acknowledge signal (TB1/9) must be connected to the control
module. If this signal is not healthy the control module will not allow the drive to run.
Power Connections
Terminations for the 3-phase supply, the d.c. output and earth/ground are detailed in Table 2–19.

Table 2–19. – Terminations For 3-Phase a.c. Supply, d.c. Output & Earth
The a.c. terminals are suitable for a maximum of 3 x 120 mm
2
cables (2 x 250 MCM in North America).
The d.c. terminals are suitable for a maximum of 3 x 185 mm
2
cables (3 x 350 MCM in North America).
To achieve the full current rating of the product, it may be necessary to use high temperature cable. See
Section 3: Drive (CDM) Design.
NOTE:
Do not allow the temperature of the cable to exceed 125°C (257°F).
The d.c. positive terminals are suitable for a maximum size of busbar at 76 mm x 6.3 mm wide (= 3 in x ¼ in).
The d.c. negative terminals are suitable for a maximum size of busbar at 140 mm x 6.3 mm wide (
≈
5.1/2 in x
1/4 in).
Ratings and sizes of busbars are application dependent.
