3.9.1 Safety notes
Please ensure you read and understand the following safety notes before you begin the UPS electrical
installation.
1. All operations detailed in this section must be performed by an authorised electrician or qualified
personnel.
2. Once the electrical installation is completed the initial UPS start-up and commissioning must be
performed by qualified personnel authorised by the manufacturer.
3. Do not operate the UPS if there is water or moisture present.
4. When carrying out any work on the UPS input power cables you must ensure that the UPS supplies are
isolated at the supply distribution panel and, where possible, locked out. Warning notices should be
posted where applicable to prevent inadvertent operation of the input supply isolators.

Before you start connecting the UPS input cables:
• Ensure that the provided fuses and cables satisfy the ratings shown in Figure 3.11, and are in
accordance with the prescribed IEC Standards or local regulations (e.g. BS7671:2008).
• Do not commence this procedure until the UPS is properly installed at its intended final location.

1. To protect personnel during the UPS installation ensure that the input cable 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.
