online one at a time by setting the string’s circuit breaker to the ON position. Verify that the breaker
does not trip, since that would indicate a swapped string connection. If you have any further ques-
tions about battery connections please contact DSPM Service Department at 1(877)377-6769.
6.1.A.
CHARGING OF THE BATTERIES: The Emergency Lighting Inverter System charges its battery
whenever it is connected to utility power and the input circuit breakers (CB1) is turned on. Dis-
connect charging source prior to connecting or disconnecting battery terminals. For the best re-
sults, charge the battery for 24 hours after they are hooked up and the ELI is brought on line.
6.2. INPUT POWER CONNECTIONS:
It is highly recommended that a qualified electrician make all input power
connections. The input power should be connected correctly at the required voltages and the ground cable
should be of the same gauge as the input power cables. In the Three Phase it is vital that a true ground be
brought into the unit. Ensure that the utility power to be connected is rated as on the system label.
Make sure the hots, neutral and grounds are correctly identified and wired to the input terminal block as
designated.
Phase rotation should be checked and verified for clockwise rotation. The DSPM UPS System will auto-
matically configure the phase rotation in the forward direction (even if the input power is miss-wired). How-
ever, the output of the DSPM UPS System will not automatically configure the phase rotation in the forward
direction while in the bypass (manual) mode. Therefore, the DSPM UPS System output power should be
checked for proper forward phase rotation while in the bypass mode.
The input power connections to the UPS come from the building supplied services. These connections are
made inside the UPS cabinet (refer to the System Component Layout). In the Three Phase, the input ca-
bles are connected to a five (5) pole terminal block(TB1) which is comprised of three (3) input power, neu-
tral, and ground connections.
6.3. OUTPUT POWER CONNECTIONS:
It is highly recommended that a qualified electrician make all input
power connections. The output power should be connected correctly at the required voltages and the
ground cable should be of the same gauge as the output power cables. Ensure that the loads to be con-
nected are as listed on the system label, and the hots, neutral and grounds are correctly identified and
are wired to the output terminal block as designated. Loads not powered by the system cannot use the
neutral of the Emergency Lighting Inverter System.
DO NOT BOND THE OUTPUT NEUTRAL TO CHASSIS GROUND! THE SYSTEM HAS
BEEN BONDED AS REQUIRED BY THE MANUFACTURER AND NATIONAL ELECTRICAL
CODE.
The Three Phase output power connections are made inside the UPS cabinet (refer to Figure 13, System
Component Layout). The output cables are connected to a three (3) pole terminal block (TB2) which is
comprised of one (1) input power, neutral, and ground connections. The output over-current protection
from the DSPM UPS System is the responsibility of the End User.
