3.2.3 UPS system interface wiring preparation
Control wiring for features and options should be connected at the customer interface terminal blocks
located on top front of the UPS, behind the door.
DANGER
Do not directly connect relay contacts to the mains related circuits. Reinforced insulation to
the mains is required.
Read and understand the following notes while planning and performing the installation:
• All interface wiring is to be provided by the customer.
• When installing internal interface wiring to Mini-slot terminals, route the wiring through the
internal opening in the Mini-slot communication bay.
• All signal inputs or remote features require an isolated normally-open contact or switch (rated at
24 VDC, 20 mA minimum) connected between the alarm input and common terminal. All control
wiring and relay and switch contacts are customer-supplied. Use twisted-pair wires for each
alarm input and common.
• The signal inputs can be programmed to display the alarm functional name.
• LAN and telephone drops for use with Mini-slot cards must be provided by facility planners or
the customer.
• The UPS Battery Aux and 24 VDC Shunt Trip signal wiring from the UPS must be connected to
the DC source disconnect device.
• Battery Aux and 24 VDC Shunt Trip wiring should be a minimum of 1.5 mm².
• The Remote EPO feature opens all switchgear in the UPS cabinet and isolates power from your
critical load. Local electrical codes may also require tripping upstream protective devices to the
UPS.
• The Remote EPO switch must be a dedicated switch not tied to any other circuits.
• A jumper wire must be connected between pins 1 and 2 on connector EPO, if the normally-
closed (NC) Remote EPO contact is used.
• Remote EPO wiring should be a minimum of 0.75 mm² and a maximum of 2.5 mm².
• The maximum distance between the Remote EPO and the UPS cannot exceed 150 meters.
• Alarm relay contacts have a maximum current rating of 5 A and a switched voltage rating of 30
VAC (RMS) and 30 VDC.
• Alarm relay wiring should be a minimum of 0.75 mm².
3.3 Unpacking and unloading the UPS
If the equipment has been transported in the upright position the outside ’Tip&Tell’ indicator on the
package surface should be intact. If the arrow has turned all blue, contact the appropriate parties for
reporting inappropriate transportation.
