CABLE INSTALLATION
Wiring Preparation
Removing the Cover Plates
On the back of
the UPS, cover
plates are over
the input and
output terminals,
as shown at right.
Remove these
using a Phillips
screwdriver. Keep
screws and plates
to one side.
Configuring the Bypass Voltage
(TB2)
The UPS voltage is factory-set to 208 V. Should
the user have a utility supply of 240 V, the bypass
voltage jumper will have to be changed to ensure
correct output voltage.
Power Cable Installation
Refer to the chart below when selecting cables
Customer-Provided Overcurrent
Protection
A branch rated overcurrent protection device
(circuit breaker or fused disconnect switch) must
be installed for the AC input.
If the start-up is on bypass, the UPS has a six-
cycle inrush current that is up to 20 times the rated
output current. This must be taken into account
when selecting the overload protection device at
the AC input supply distribution point. To avoid
random tripping on start up, it is recommended
that the AC input supply be protected with a circuit
breaker capable of withstanding this initial inrush.
This UPS is fitted with EMI suppression filters.
Earth leakage current is less than 40mA. Transient
and steady state earth leakage currents may occur
when starting the equipment. This should be taken
into account when selecting ground current
detection devices, as the earth leakage currents of
both the UPS and load will be carried.
Input and output cables must be run in separate
conduits.
WARNING:
Please read this section thoroughly before
attempting to install wiring to this unit.
Be sure that the unit is not connected to any
power source before installing any wiring to this
unit. This UPS should be installed by a
qualified / certified electrician.
