2.4.1 Wiring Schematics

A complete set of wiring schematics and connection diagrams will be provided for each job. Each set of
wiring schematics and connection diagrams are job specific. The job name and number will be listed in the
bottom right corner of each page of these documents.

2.4.2 Proper Field Wiring

Most of the field connections to GALaxy controls are made using stranded wire. When inserting this
stranded wire into the terminals – especially those for EPD's (Electrical Protective Devices) – care must
be taken to ensure that all the strands are properly inserted into the terminals. Improper stripping and
insertion may leave strands outside of the terminals. Strands not properly inserted into the terminals
may make contact with wires from an adjacent terminal.
The danger associated with an occurrence as described above has led GAL Manufacturing to
recommend that, for all connections to the Electrical Protective Devices listed in ASME A17.1-
2016/CSA B44-16, Requirements 2.26.2.1 through 2.26.2.39, elevator personnel must follow the
guidelines listed below:
•
Inspect all terminals used to connect Electrical Protective Devices. Ensure that the cage clamp is
fully open before inserting a wire into the terminal block.
•
Perform corrective action for wires with stray strands by one of the following methods:
o
Reconnect the wire with all wire strands correctly installed into the terminal. Visually
verify that no wire strands are outside of the terminal. The conductor should be stripped
and inserted completely into the terminal in such a manner that no more than two
millimeters of bare wire is visible; or
o
Attach a ferrule to the end of field wire for safety devices (as pictured in Figures 0-1 and
0-2) and insert the ferrule into the terminal; or
o
Use an acceptable method such as tinning.
•
After removal and replacement of any of these field wires, the actual Electrical Protective Device
should be checked for proper operation.

2.4.3 Ground Wiring

Proper grounding of the power supply, controller, elevator car, and hoistway is required. Separate
conductors should be run for EG (earth ground) and GND terminals. These terminals and conductors
are detailed on the wiring schematics.

2.4.4 Hoistway Wiring

All hoistway wiring is detailed on the wiring schematics and connection diagrams. The number of
required hoistway conductors is listed in the connection diagrams. A job specific "pull sheet" is also
included in the connection diagrams.
