Installation Into Inverter
The installation procedure and points of caution are as described below.
(1) Remove the inverter unit's front cover.
CAUTION
1. Wait at least 20 minutes after turning the power OFF before starting work. Make sure that the
displays on the operation panel have gone out before removing the cover.
2. After removing the cover, confirm that the “CHARGE” LED on the unit has gone out.
Also check that the voltage between terminals L+1 or L+2 and L- is 15V or less before starting
the inspections.
(Check with the “CHARGE” LED if the unit is not provided with the L- terminal.)
(2) If the other option PCB is installed onto the position for option
II
on the control PCB cover,
install this PCB onto the position for option
III.
Refer to Fig. 2-1.
(3) When wiring to TB1 use AWG26 to 16 (0.14 to 1.5mm
2
) for the wires.
Wires should be terminated correctly, with suitable crimp terminals or ferrules.
Pass the wires through the cable connection hole on the inverter unit and then connect.
CAUTION
1. Observe the cautions listed in Fig. 3-1 and Section 2-4 in the VAT2000 Instruction Manual
(PCST-3251) when wiring.
