GAL GALaxy eHydro Manual page 8

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 below 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.
