Dc Cable Connections; Wiring The Battery Bank - Apollo Solar 3224 User Manual

requires that the DC wiring and circuit protection be sized to carry not less than 125% of
the inverter's maximum current rating.
Crimped and sealed copper ring terminal lugs with a 5/16" hole should be used to
•
connect the DC wires to the DC terminals.
To ensure the maximum performance from the inverter, all connections from the battery
•
bank to the inverter should be minimized.
All wiring to the battery terminals should be checked periodically (once a month) for
•
proper tightness. The torque requirement is 5 ft-lb (6.78 N-m).
Refer to Table 4.1 for proper wire sizing.

4.3.1.1 DC Cable Connections

When connecting the DC cable to the battery or inverter input terminals, the cable should be placed
directly against the inverter or battery terminals. Incorrectly installed hardware can cause a high
resistance connection which could result in poor inverter/charger performance and/or high heat which
can melt the cable and terminal connections.
CAUTION
Use proper torque when tightening the inverter's DC terminal nuts. Assure that the cable lug is
firmly seated against the body of the connector. It is advisable to use an anti-seize lubricant to
prevent binding.
ATTENTION
Employez le couple approprié en serrant les écrous terminaux du C.C de l'inverseur. Assurez
que le crochet de câble est fermement posé contre le corps du connecteur. Il est recommandé
d'employer un lubrifiant anti-grippage pour empêcher lier.

4.3.1.2 Wiring the Battery Bank

WARNING
Lethal currents will be present if the positive and negative battery cables touch each other.
During the wiring process, ensure the cable ends are insulated or covered to avoid shorting to
each other.
AVERTISSEMENT
Les courants mortels seront présent si les câbles positifs et négatifs de batterie se touchent.
Pendant le processus de câblage, assurez que les extrémités de câble sont isolées ou couvertes
pour éviter de court-circuiter entre eux.
IMPORTANT
Do not connect the cables from the battery bank to the inverter until 1) all DC and AC wiring is
complete, 2) the correct DC and AC current protection has been installed and 3) the correct DC
voltage and polarity has been verified.
IMPORTANT
Ne reliez pas les câbles de la banque de batterie à l'inverseur jusque 1) à tout le C.C et le
câblage à C.A. est complet, 2) la protection courante correcte de C.C et à C.A. a été installée et
