USN Installation
3
Mounting the Board Assemblies
1. Determine an appropriate location for the USN-BASE assembly. (Preferred location is
in the upper left quadrant of the control enclosure.)
2. Mount the board, facing outward, such that access to critical controller components is
not blocked.
3. For PTC/PHC programmable controllers, mount the M2C assembly near the USN-BASE
assembly. (For a duplex, mount an M2C assembly in each controller enclosure but just
one USN-BASE assembly in the enclosure of your choice.)
Motion 3000ES Installation
For Motion 3000ES, only the USN-BASE assembly is required. Special hinged stand-offs will
be provided to mount the USN-BASE (HC-MPU) board assembly.
Mounting the Board Assemblies
1. Determine an appropriate location for the USN-BASE assembly.
2. Mount the board, facing outward, such that access to critical controller components is
not blocked.
USN Power Connection, Elevators
Before the USN can be configured, it must be powered up. But, no communication connections,
serial, Ethernet, or CAN, should yet be attached.
1. Connect the provided leads to the power transformer.
2. Connect the power transformer leads to AC1/AC2 on the top right side of the USN-BASE
assembly.
3. Plug the power transformer into the AC receptacle in the controller. (Note: If alternate
outlet is used, power must be in phase with controller 110 VAC.)
Power Connection, Escalators
The power transformer is not required for Motion 3000ES escalator installations.
1. Using 18 AWG, white, teflon coated wires, connect HC-MPU, 16V1 to escalator board
EC-MCB, CL1 and HC-MPU, 16V2 to EC-MCB CH1.
