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.
Do not connect relay contacts directly to the mains-related circuits. Reinforced insulation to the
NOTE:
mains is required.
Read and understand the following notes while planning and performing the installation:
•
The customer must provide all interface wiring.
•
When you install internal interface wiring to MiniSlot terminals, route the wiring through the internal
opening in the MiniSlot 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 MiniSlot 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. Also 48 Vdc Shunt Trip signal can be utilized. See Figure
wiring for 93PM G2 UPS.
•
Battery Aux and Shunt Trip wiring should be a minimum of 1.5 mm
•
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 mm
•
The 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 mm
