6.1 Safety
WARNING
WARNING
Danger to life due to lethal voltages!
High voltages which may cause electric shocks are present in the
conductive parts of the inverter. Prior to performing any work on
the inverter, disconnect the inverter on the AC and DC sides
Danger of damage to electronic components due to electrostatic
discharge.
Take appropriate ESD precautions when replacing and installing
the inverter.
6.2 Wiring AC Output
You must install a separate single-phase circuit-breaker or other load disconnection unit
for each inverter in order to ensure that the inverter can be safely disconnected under
load.
We suggest you choice the AC breaker rating current in this table:
MIN 2500 TL-XH/XE
16A/230V
16A/230V
20A/230V
25A/230V
25A/230V
32A/230V
32A/230V
MIN 4200 TL-XH/XE
MIN 3000 TL-XH/XE
MIN 4600 TL-XH/XE
MIN 3600 TL-XH/XE
MIN 5000 TL-XH/XE
MIN 6000 TL-XH/XE
The AC wiring step:
1.Uninstall the parts of the AC connection plug from the accessory bag.
2.Insert the stripped and bared cable through pressure screw, seal ring, threaded sleeve
in sequence, insert cables into connection terminal according to polarities indicates on
it and tighten the screws firmly. Please try to pull out the wire to make sure the it’s well
connected.
ØYou must install a separate single-phase circuit-breaker or other
load disconnection unit for each inverter in order to ensure that
the inverter can be safely disconnected under load.
NOTE :
The inverter has the function of detecting residual current and
protecting the inverter against residual current. If your inverter has to
equip a AC breaker which has the function of detecting residual
current ,you must choose a AC breaker with the rating residual
current more than 300mA.
