1.3 Safety
A proper and effective ground connection is required for the safe and successful operation of
the controller. Ensure that each elevator controller disconnect has a sufficient earth ground
provided from the building to the disconnect and is run to the earth ground inside the
individual elevator controller (PE).
Note: The size of the ground wire should match the same size (AWG) as the controller ground
lug wire internal inside the controller.
The system has one or more common ground bus terminal blocks (PE).
Figure 6: Ground Bus Terminal Blocks
The building, motor, governor (if applicable), transformer, and filter(s) must all share a common
ground. Inefficient grounding can cause many types of issues with modern elevator control
systems.
Proper grounding removes ground loops, limits impedance, and routes electrical noise to earth
ground.
1.4 Default Voltage Settings Prior to Installation
While Smartrise takes every measure to provide the customer with an out-of-box installation,
sometimes incomplete information leads to default values being set on equipment and voltage
settings. This is done to protect the equipment from overvoltage issues. For example, the door
operator for that job might operate at 240 VAC but if Smartrise was not provided with that
information when the job was developed, the DR breaker (door operator voltage supply) is set
to 120 VAC for safety reasons.
Verify, according to the provided drawings, that all required voltages for the existing equipment
matches the voltages set by Smartrise PRIOR to powering up the controller.
