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.
T
he 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.
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.
The input power connections to the UPS come from the building supplied services. These connections are
made inside the UPS cabinet (refer to Figure 12a-b, System Component Layout). The input cables are
connected to a three (3) pole terminal block(TB1) which is comprised of one (1) input power, neutral, and
ground connections.
6.3. OUTPUT POWER CONNECTIONS
It is highly recommended that a qualified electrician make all input power connections.
T
he 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 connected are as listed on the system label,
and the hots, neutrals 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 In-
verter 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 output power connections are made inside the UPS cabinet (refer to Figure 12a-b, System Compo-
nent 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.
