4: Installation Procedure
4.4.3 Connecting the UPS Input mains cables
1. Gain internal access to the UPS:
a) Unlock and open the UPS door.
b) Remove the lower cover plates to expose the power connection busbars.
c) Remove the perspex safety covers from in front of the power connections to gain full access.
Note: The connection terminals are identified on the perspex cover
2. Connect the earth cable from the mains distribution board to the UPS protective earth (PE) busbar – see Figure 4.5.
Single Input Feed
3. Ensure the single-feed links are connected between the input supply terminals and bypass input terminals
(1-L1 to 2-L1, 1-L2 to 2-L2 and 1-L3 to 2-L3) – see Figure 4.5.
4. Connect the UPS input supply cables to terminals 1-L1, 1-L2, 1-L3. Ensure correct (clockwise) phase rotation.
5. Connect the input neutral to the Neutral busbar.
Dual Input Feed
6. Remove the single-feed links if fitted – see Figure 4.5.
7. Connect the UPS input mains supply cables to terminals 1-L1, 1-L2, 1-L3. Ensure correct (clockwise) phase rotation.
8. Connect the input neutral to the Neutral busbar.
9. If the bypass mains supply is obtained from a different mains distribution board to the input mains supply, connect an
earth cable from the bypass mains distribution board to the protective earth (PE) busbar – see Figure 4.4.
10. Connect the UPS bypass supply cables to terminals 2-L1, 2-L2, 2-L3. Ensure correct (clockwise) phase rotation.
11. Connect the bypass neutral to the Neutral busbar.
Note: The UPS commissioning engineer will re-configure the UPS electronics to operate with a dual feed input at the time
of commissioning.
4.4.4 Connecting the UPS output cables
We recommend that a dedicated load distribution board is connected between the UPS output and the load.
Before you begin connecting the UPS output cables to the load distribution board:
• Verify that the projected load does not exceed the UPS output power rating (
OUTPUT POWER
on the nameplate).
• Ensure the load circuit breakers on the load distribution board are correctly sized with respect to the individual load
rating and associated cabling.
• Ensure that the maximum total load rating, and the maximum load rating of each individual load socket, is indicated
on the load distribution board.
The circuit breakers must comply with the prescribed IEC Standards – e.g. BS7671.
1. Connect the earth cable from the load distribution board to the UPS protective earth (PE) busbar – see Figure 4.4.
2. Connect the UPS 3-phase output cables between terminals 3-L1, 3-L2, 3-L3 and the appropriate connections at the
load distribution board. Ensure correct (clockwise) phase rotation.
CAUTION:
The input Neutral cable must be unswitched and grounded.
CAUTION:
The input Neutral cable must be unswitched and grounded.
CAUTION:
If the input mains and bypass mains supplies are obtained from the same 3-phase power source
it is not necessary to connect a separate bypass mains supply neutral.
