For both power and earth conductors, TSi Power also recommends using stranded
copper wire with a 105 °C insulation system.
3.64
Allow for sufficient wire length to reach the wiring terminals and leave enough slack to
reduce the stress in the wires. Note: Two wires plus ground are required for primary and
backup input and ATS output.
3.65
Strip approximately 3/8
"
(10 mm) insulation from the end of each of the three (3) sets of
wires and terminate them in the wiring terminals as follows.
3.66
Using a slotted screwdriver,
terminate the incoming primary wires on the terminal blocks
behind the rear cover marked “Primary Input”. These terminals are marked as follows:
•
LI
for primary input line (or
L1in
for primary input phase 1)
•
NI
for primary input neutral (or
L2in
for primary input phase 2)
•
PE
for primary input protective earth (European systems);
G
for primary input earth
ground (North-American systems)
3.67
Using a slotted screwdriver,
terminate the incoming backup wires on the terminal blocks
behind the rear cover marked “Backup Input”. These terminals are marked as follows:
•
LI
for backup input line (or
L1in
for backup input phase 1)
•
NI
for backup input neutral (or
L2in
for backup input phase 2)
•
PE
for backup input protective earth (European systems);
G
for backup input earth
ground (North-American systems)
•
3.68
Using a slotted screwdriver,
terminate the outgoing wires on the terminal blocks behind
the rear cover marked “AC Output”. These terminals are marked as follows:
•
LO
for AC output (or
L1out
for AC output phase 1)
•
NO
for AC neutral output (or
L2out
for AC output phase 2)
•
PE
for output protective earth (European systems);
G
for output earth ground (North-
American systems)
•
3.69
Carefully insert each wire into the appropriate slot, taking care to ensure that all strands
are inserted properly. Tighten the terminal screw using a slotted screwdriver and torque
the terminations for the 15, 20 or 30 A units 0.79 Nm (7 in-lb) and for the 40 A are 2.26
Nm (20 in-lb). Perform a pull test to make sure the connection is secure. Do not apply
excessive torque to make sure that the terminal screws are not damaged. Note that
failure to follow these instructions can lead to malfunction or short circuit.
