Series 7400 Single Phase 1+N UPS

6.Connect the safety earth and any necessary bonding earth cables to the copper earth busbar located on the floor of the equipment below the power connections.

Note:- The earthing and neutral bonding arrangement must be in accordance with local and national codes of practice.

7.Connect the battery circuit breaker control cables between the UPS auxiliary terminal block and battery circuit breaker controller board as shown in figures 19 & 20.

8.If an external emergency stop facility is to be used then remove the link between terminals 4 and 5 of the auxiliary terminal block and connect the ‘normally closed’ remote stop circuit between these two terminals.

Note:- Terminals 8 and 9 on the auxiliary terminal block are connected to a pair of ‘normally closed’ contacts on the UPS emergency stop button and will go open circuit when the emergency stop pushbutton is pressed. These terminals can be used to control an external circuit breaker connected in the UPS input mains supply line to isolate the UPS input power when the emergency stop button is pressed.

9.Connect one-plus-one parallel control ribbon cables between the Parallel Interface boards of both modules. Connect one ribbon cable between sockets CN1 on one board and CN2 on the other, and connect the second ribbon cable between the remaining CN1 and CN2 sockets. Refer figure 10.

10.Maintenance bypass switch auxiliary wires at terminals 10 & 11 should be connected to other module terminals 10 & 11.
