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 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.
3.6.2 Preparation for the input cabling
Before you start connecting the UPS input cables:
• Ensure that the provided fuses and cables satisfy the ratings shown in Figures 3.4 and 3.6/ 3.7, and
are in accordance with the prescribed IEC Standards or local regulations.
• Do not commence this procedure until the UPS is properly installed at its intended location.

following conditions:
a)
No mains voltage is present.
b)
Loads are shut down and disconnected.
c)
The UPS is shut down and voltage-free.

4.
The Kohler PW 5000/TP input supply can be wired for ‘single feed’ (standard) or ‘dual feed’ operation.
Connect the input power cable coming from the LV-Distribution Board to the UPS input terminals
following the ‘single input feed’ or ‘dual input feed’ given below.
Single Input Feed

Refer to the schematic drawing and connection table in Figure 3.8. Connect the UPS input supply cables
to terminals 1L1, 1L2, 1L3 and 1N on the UPS main terminal block
(See Figures 3.6 /3.7)
. Ensure correct
(clockwise) phase rotation.
2.
Secure the cables to the fixing rail under the connection terminals.
3.
10kVA – 25kVA Models only: Ensure the bypass cables are connected to the correct terminals on the
Filter Board (see Figure 3.6). These will be reconfigured by the commissioning engineer if necessary.
WARNING:
Opening or removing the UPS-covers will create the risk of exposure to
dangerous voltages if power is connected to the UPS.
CAUTION: The input Neutral cable must ALWAYS be connected.
