SECTION 4 Electrical Installation Overview Each of the pieces of equipment covered by this manual has four sets of power connections: 1. Input from the power source, typically, from the electric utility. 2. Power routed to the input of the UPS. If the bypass and rectifier inputs are powered from separate sources, the bypass input must be fed from the MBS. - Page 11 5. Select wire size in compliance with Table 3. 6. Recommended crimp terminal lugs are shown in Table 4. The power and neutral terminal pads, see Figure 4 and Figure 5, are provided with 3/8-16 bolts.

SECTION 5 Operation Refer to the User's Manual for the UPS for instructions on operating the UPS part of the system. If the UPS is part of a parallel system, special operating instructions apply. Maintenance Bypass Switch (MBS) The purpose of the Maintenance Bypass Switch (MBS) is to facilitate servicing the UPS without removing power from the load. - Page 16 Common MBS operations: (refer to the UPS manual for UPS operations; BKR1, BKR2, BKR3 are part of the Maintenance Bypass Switch Cabinet; all other switches are part of the UPS) To transfer from normal mode on the UPS to maintenance bypass— 1.
- Page 17 Need to get power to the load, but the condition of the UPS is uncertain— 1. Verify that the load is truly not powered. 2. Verify that the utility source is suitable (applying power to the load using the MBS is at the operator’s risk).

SECTION 6 Maintenance There are no wear items in the MBS that require periodic replacement. However, regular care will assure maximum availability of power. Keep the ventilation openings in the cabinet free of dust and debris. Wipe the cabinet exterior with a soft cloth, slightly dampened with water, to remove dust. Consider performing periodic infrared temperature measurements on the circuit breaker terminations.
