Electrical Installation
Top Cable Entry
When making the power connections, the recommended order of pulling and installing cables is to start from the top connections to the bottom connections. The cables must be routed around the fault braces (see Detail in Figure 3). This is to prevent the cables from contacting other busbars. The recommended conduit layout is shown in Figure 1.
Bottom Cable Entry
When making the power connections, the recommended order of pulling and installing cables is to start from the bottom connections to the top connections. The cables must be routed around the fault braces (see Detail in Figure 3. This is to prevent the cables from contacting other busbars. The recommended conduit layout is shown in Figure 1.
NOTE
For a Single Input configuration, linking busbars must be installed between the bypass and the rectifier input.
! WARNING
Risk of electrical shock. Can cause injury or death.
If the load equipment will not be ready to accept power on the arrival of the commissioning engineer, ensure that the system output cables are safely isolated at their termination.
! WARNING
Risk of electrical shock. Can cause injury or death.
When connecting the cables between the battery extremities to the circuit breaker always connect the circuit breaker end of the cable first.
NOTE
If fault bracing brackets were removed during installation, they MUST be replaced.
5. Close and secure the interior and exterior doors.
