CAUTION!
Failure to observe grounding procedures may lead to the risk of electrical shock, or the risk of fire if a ground
fault occurs.
Remember to connect the ground at the marked point
.
Ground connections must be in compliance with local regulations and applicable standards.
CAUTION!
For compliance with CSA 107.1-16, the installer shall mark the C-Cab with the following wording or
equivalent, located on or adjacent to the DC wiring compartment:
“DANGER — HIGH VOLTAGE” Or “DANGER 860V”
CAUTION!
The AC output circuits are isolated from the enclosure and the AC system grounding, when required by the
Canadian Electrical Code, Part I, is to be done in the installation.
Note: the L1, L2 and L3 wires shall be connected respecting a
clockwise phase rotation
, i.e. L1 anticipates L2 and
L2 anticipates L3.Some utilities may adopt a counterclockwise phase rotation as standard, so the names or colors
indicated on the cables may not match the names indicated on the C-Cab AC bars.
Verify the actual phase rotation before connecting the AC cables.
