Ground Wiring
Both input and output ground studs are provided and marked with label. Hardware is also supplied.
Frames 4 thru 6 have 10-32 studs on the back panel, and the supplied nut, flat washer and lock washer should be torqued to
30 lb-in
Frame 7 has 1/4-20 studs on the back panel, and the supplied nut, flat washer and lock washer should be torqued to 65 lb-in
Control Wiring
No additional control wiring is necessary for basic operation - see schematic for Auto Start contact, Auto reference connec-
tions and interlock connections to control PCB terminal block if required.
See H-Max Installation manual MN04008005E for more information on control wiring and control board layout and connec-
tions.
For ease of access the control terminals blocks can be unplugged for wiring.
All control I/O wiring must be segregated from line (mains) and motor cabling.
Run 120 Vac and +24 Vdc control I/O in separate conduit if applicable.
Control I/O terminals must be tightened to 4.5 lb (0.5 Nm).
In addition, the IntelliPass models provide an additional “External Interlock” input on TBA 2 & 3. This can be used to remove
the 24V power from the contactors and door control elements. If is factory jumpered. If removed, it removes 24V power to
the bypass and drive contactors. It does not disable the drive from running, only from being connected to a motor. Under
some circumstances the drive/bypass could still be commanded to run but since the contactors are disabled, the motor will
not run, however the drive keypad may indicate it is running. Refer to the schematic
This external interlock input is not supplied on the IntelliDisconnect models unless the output contactor with power supply
option is supplied. Refer to the schematic.
