Installation
Refer to the Technical manual, TM.V7.01, for installation, set-up, and operating instruction for
the drive.
Note
It is necessary to first connect all power terminals (input and output power, DC link
choke, DB resistor) if they are to be utilized before installing the 120VAC interface
card. Once the card is installed, access to these terminals is not possible.
(1) Turn off all power supplies to the V7 and the 120VAC interface card.
(2) Remove the drive’s front cover. Verify that the CHARGE indicator lamp is off.
(3) Use a voltmeter at the incoming power terminals (L1, L2, L3) and the 120VAC leads
to verify that power is disconnected.
(4) Make all connections to the terminals referred to in the Note above prior to
continuing this installation procedure.
(5) Loosen the screws at the drive control board terminals S1, S2, S3, S4, and SC.
(6) Slide the forked extensions on the interface card into the terminals listed above (see
Figure 1) and re-tighten terminal screws securing the board in place.
(7) Attach the three (3) pigtails of the 120VAC interface card to terminals S5, S6, and
S7 (see Figure 1). Connect other conductors to proper drive terminals as required
for your application.
(8) Connect external control signal wiring to Terminal TB1. (see Figure 1 for default 2-
wire control connections)
(9) Check conductor routing to ensure that no conductors are in contact with the
resistors that are mounted on top of the DS-085 interface card.
(10) Check for loose connections and inspect wiring.
(11) Set drive control inputs to NPN (default). See the drives technical manual TM.V7.01
for instructions.
(12) Replace the front cover. Apply power to the drive and 120VAC interface card and
proceed with the setup as described in the V7 Technical Manual.
Note
Since there are two (2) power supplies connected to the drive, one for main circuit
power and one for the 120VAC interface card, the user must provide for the
possibility of one supply being on when the other is off.
Be careful when installing control wiring to terminal TB1 and use minimum pressure
on the board to avoid damaging or breaking the forks installed into the drive
terminals.
