8.4. Electrical installation
FOR YOUR SAFETY: IT IS IMPERATIVE THAT ALL SOURCES OF POWER (AC & DC) ARE PROVEN
DISCONNECTED BEFORE ANY WORK ON OR PHYSICAL CONTACT TO ELECTRICAL CIRCUITS IS
ATTEMPTED.
DO NOT ASSUME BUT CHECK ACROSS THE LINES AND TO GROUND WITH A RELIABLE VOLTMETER
AND ENSURE THAT THE SOURCE D ISCONNECTION DEVICES ARE SECURELY LOCKED OUT .
THE MANUAL SWITCH DISCONNECT IN EACH BATTERY CABINET SHOULD BE IN THE OFF POSITION .
LOCK OUT AND TAG OUT PROCEDURES SHOULD BE FOLLOWED WHEN SERVICING THE EQUIPMENT.
Each battery cabinet is provided with an isolation switch QS to cut off the output of the batteries and breakers QF1 & QF2
(behind the cover) to cut off supply to chiller and controls of battery system. These switch & breakers are accessible from
the control box located at left-hand side of each B-Cab. Additionally, each battery modules in the cabinet are provided with
a Manual Switch Disconnect (MSD) for safety. Before proceeding to wiring, ensure that the isolation switch QS and the
breakers QF1 & QF2 in the battery cabinets are in OPEN (OFF) position as illustrated after.

8.4.1. Battery Cabinet Interconnections
DANGER!
Risk of electrical shock including high short-circuit current as batteries are a source of electrical energy. Use
only insulated tools around the modules and batteries and carefully avoid shorting the battery terminals or
connections.
CAUTION!
Inadvertent short circuits are the major cause of failures for batteries. Risks associated with shorting as well as
other hazardous conditions can be mitigated by carefully following the listed guidelines below.
Handling Precautions and Guidelines
• Wear appropriate Personal Protective Equipment (PPE) with due attention to eye protection in addition to insulated gloves.
• Remove all metallic objects from the person (e.g., Watches, jewelry, etc.) that could potentially contact the live battery
terminals.
• All tools used around the battery assembly should be insulated or covered with, a non-conductive material.
The batteries require interconnections for DC power, auxiliary power, communication, and ground. The cables are provided
for each connection and are labelled for ease of identification as they are of different lengths for each battery cabinet
connections. Battery interconnections can be installed using the factory provided cable gutter.
