4: Installation Procedure
4.5.3

Connecting the power cables (single-feed input)

1. Connect an earth cable from the input mains switchboard to the UPS protective earth terminal (PE).
2. If an external battery cabinet is used, connect an earth cable between the battery cabinet and the UPS battery earth
terminal (PE).
3. Ensure the single-feed links, shown in yellow in Figure 4.11, between the input mains terminals and bypass mains
terminals (i.e. 1-L1 to 2-L1, 1-L2 to 2-L2 and 1-L3 to 2-L3) are fitted.
4. Connect the UPS input mains supply cables to terminals 1-L1, 1-L2, 1-L3. Ensure correct (clockwise) phase rotation.
5. Connect the input mains neutral to terminal 1N.
CAUTION: The input neutral cable must be unswitched and grounded.
4.5.4

Connecting the power cables (dual-feed input)

1. Connect an earth cable from the input mains switchboard to the UPS protective earth terminal (PE).
2. If the bypass mains supply is obtained from a different mains switchboard to the input mains supply, connect an earth
cable from the bypass mains switchboard to the protective earth terminal (PE).
3. If an external battery cabinet is used, connect an earth cable between the battery cabinet and the UPS battery earth
terminal (PE).
4. Remove the single-feed links, shown in yellow in Figure 4.11, between the input mains terminals and bypass mains
terminals (i.e. 1-L1 to 2-L1, 1-L2 to 2-L2 and 1-L3 to 2-L3). Leave the neutral link connected between 1N and 2N.
5. Connect the UPS input mains supply cables to terminals 1-L1, 1-L2, 1-L3. Ensure correct (clockwise) phase rotation.
6. Connect the input mains neutral to terminal 1N.
7. Connect the UPS bypass mains supply cables to terminals 2-L1, 2-L2, 2-L3. Ensure correct (clockwise) phase
rotation.
8. If the bypass mains supply is obtained from a different mains switchboard to the input mains supply, connect the
bypass mains neutral to terminal 2N (ensure the neutral link is connected between 1N and 2N).
Note: If the input mains and bypass mains are connected to the same switchboard the 2N cable is not necessary.
CAUTION: The input neutral cable(s) must be unswitched and grounded and the neutral terminals 1N & 2N
must be linked.
Note: The UPS commissioning engineer will re-configure the UPS electronics to operate with a dual feed input at the time
of commissioning.
4.5.5

Connecting the UPS output cables

We recommend that the UPS AC output is connected to a dedicated output distribution panel.
Before you connect the UPS output cables to the output distribution panel:
• 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 output distribution panel are correctly sized with respect to the individual
load ratings and associated cabling.
• Ensure that the maximum total load rating, and the maximum load rating of each individual load socket, is indicated
on the output distribution panel.
1. Connect the earth cable from the output distribution panel to the UPS protective earth (PE) terminal.
2. Connect the UPS AC output cables between terminals 3-L1, 3-L2, 3-L3 and the appropriate connections at the load
distribution panel. Ensure correct (clockwise) phase rotation.
3. Connect the UPS output neutral cable between terminal 3-N and the load distribution panel.
CAUTION: The output neutral cable must ALWAYS be connected.
