8.4.3.2. Grounding
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.
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.
Grounding is used for equipment and personnel safety. The SUNSYS HES L is designed to operate with 3-wire and 4-wire
grounded sources and is compatible with solidly grounded or resistance grounded systems. All input and output power
feeds must include an equipment grounding means as required by the local codes.
The equipment ground conductors should be sized based on the upstream overcurrent protection per code and connected
to the sole Ground Terminal.
A ground connector with cross section at least equal to half of main conductor size is recommended.
The following instructions describe the method of routing ground cables from each B-Cab to the termination compartment,
these are supplied by Socomec. In the instructions below, B-Cabs are referred relative to their position from the C-Cab.
WARNING!
Ensure that there is no power applied to the unit
Ensure the isolation switch QS and the breakers QF1 & QF2 in each battery cabinet are in OPEN position
Ensure all MSD covers in each battery cabinet are not installed
1. Check with a reliable voltage indicating device that both DC and AC terminals in battery and termination compartments
have close to zero potential.
2. For the first B-Cab,
a. Lay the cable on the ground in front of the cable gutter between the B-Cab and the termination compartment.
b. For the B-Cab, route one end of the cable through the bottom hole in the gutter and the B-Cab access hole.
c. Connect to the ground terminal and bolt using the provided hardware and torque.
d. For the termination compartment, route the other end of the cable up from the gutter opening into the bottom of
the termination compartment while laying the cable into the rear of the gutter.
Note: ensure the cable is laid straight without any excessive slack.
e.Connect to the ground terminal and bolt using the provided hardware and torque.
3. Then, connect the ground from B-Cab 1 and B-Cab 2, then B-Cab 2 to B-Cab 3… in a daisy chained manner.
