3.10.2 Preparation for the output cabling
The output of the UPS must be fitted with circuit breakers (or equivalent protection) connected between the
UPS and individual pieces of load equipment. These circuit breakers provide additional protection to the UPS
in the event of an overload or short circuit and also provide a means of isolating individual loads if required.
Before you start connecting the UPS output cables to the load distribution panel:
• Ensure that the potential load does not exceed the UPS model output power rating (OUTPUT
POWER) on the nameplate.
• Ensure the output circuit breakers are correctly sized with respect to the load rating and cabling.
• The maximum total load rating and maximum load rating of the individual load sockets should be
indicated on the output distribution board.
• The circuit breakers must comply with the prescribed IEC Standards (e.g. BS7671:2008). It is
recommended that a separate output distribution board is provided for the load.
3.10.3 Connecting the UPS output cables
1. To protect personnel during the UPS installation ensure that the connections are performed under the
following conditions:
a) No mains voltage is present.
b) Loads are shut down and disconnected.
c) The UPS is shut down and voltage-free.
d) The UPS Maintenance Bypass Isolator IA1 is OFF.
2. Gain internal access to the rear of the UPS and remove the UPS terminal cover.
3. Connect the protective earth cable from the Load Distribution Board to the output protective earth (PE)
terminals, as shown in Figure 3.12.
4. Connect the UPS output supply cables to terminals 3L1, 3L2, 3L3 and 3N on the UPS main terminal
block
(See Figure 3.12)
. Ensure correct (clockwise) phase rotation.
5. Secure the cables to the fixing rail located under the UPS connection terminals.
6. Ensure the output cables are connected to the correct power terminals on the output distribution panel.
3.11 Connecting the Batteries
3.11.1 Safety notes
1. For personal protection, ensure that the battery cables are connected under the following conditions:
a) No mains voltage is present in the UPS.
b) All loads are disconnected.
c) The battery isolators (internal and/or external) are open.
3.11.2 Battery configuration options
The batteries used in conjunction with the RI-11, RI-12, RI-21 and RI-22 models are internally mounted on
shelves that can each house up to forty 7Ahr or 9Ahr 12V battery blocks. In the case of the RI-10, RI-20 and
R1-40, the batteries are contained in a purpose-designed, external battery cabinet or rack-mounted. Where
an external battery installation is used an isolator must be fitted adjacent to the batteries (for example, within
the battery cabinet) to provide a means of isolating each battery string from the main equipment.
CAUTION: The output Neutral cable must ALWAYS be connected.
WARNING:
The final assembly and connection of the battery units must be carried out under
the supervision of the commissioning engineer. Do not attempt to complete the battery wiring
or close the battery isolators before this system has been commissioned.
