UPS Electrical Installation

Bottom Cable Entry

When making the power connections for bottom cable entry, the recommended order of pull- ing 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 9). This is to prevent the cables from contacting other busbars. The recommended conduit layout is shown in Figure 7.

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.

5.For control connection details, see 2.3 - Control Cable and Communications.

NOTE

If fault bracing brackets were removed during installation, they MUST be replaced.

6. Close and secure the interior and exterior doors.

2.3Control Cable and Communications

Based on your site’s specific needs, the UPS may require auxiliary connections to manage the battery system (external battery circuit breaker), communicate with a personal computer or provide alarm signaling to external devices or for Remote Emergency Power Off (REPO). The External Interface Board, arranged for this purpose, is on the rear of the operator access door.
