Personnel Safety - O. Thompson Microflite Ultra 2000 Installation & Adjustment Manual

Section 2 Personnel Safety
There are certain fundamental warnings that must be kept in mind at all times. If these fundamental
warnings are not kept in mind, personal injury and/or death may occur. These Warnings include,
but are not limited to:
•
MicroFlite Controllers should only be installed by qualified, licensed, trained elevator personnel
familiar with the operation of microprocessor-based elevator controls.
•
Verify that all safety devices ( limits, governors, hoistway locks, car gate, etc) are fully functional
prior to attempting to run the elevator. Never operate the MicroFlite controls with any safety device
rendered inoperative in any way.
•
The User is responsible for compliance with the current National Electrical Code with respect to the
overall installation of the equipment, and proper sizing of electrical conductors connected to the
controls.
•
The User is responsible for understanding and applying all current Local, State, Provincial, and
Federal Codes which govern practices such as controller placement, applicability,
protection, disconnections, overcurrent protection, and grounding procedures.
•
Controller equipment is at line voltage when AC power is connected. Never operate MicroFlite
controls with covers removed from SCR Drives, Motor Field, or Brake controls.
•
After AC power has been removed, internal capacitors can remain charged for up to 5 minutes
after power has been removed. Therefore, wait at least 5 minutes after power down before
touching any internal components of the controls.
•
To prevent the risk of personal shock, all equipment should be securely grounded to earth ground,
with a minimum of #8 AWG wire as outlined in the National Electrical Code. Failure to obtain an
actual earth ground source may result in electrical shock to personnel.
•
When using test equipment (oscilloscopes, etc.) with a power cord that electrically ties probe
common to earth ground, an isolation transformer should be used to isolate the instrument
common from earth ground.
•
Care should be taken to remain clear of all rotating equipment while working on the controls.
