3.7.1
Installing a PG Speed Option Card
Use the following procedure to install a PG Speed Option Card:
1. Turn OFF the main-circuit power supply.
2. Leave it OFF for at least one minute before removing the front cover of the Inverter (or at least three minutes for
Inverters of 30 kW or more). Check to be sure that the CHARGE indicator is OFF.
3. Insert the spacer (which is provided) into the spacer hole in the Inverter’s mounting base.
For Inverters of 3.7 kW or lower, there are two adjacent holes. Insert the spacer into the 7CN hole. The spacer
cannot be easily removed if inserted into the wrong hole. Be very careful to insert the spacer into the correct hole,
and in the proper direction.
4. Referring to the enlarged illustration in the following diagram, align the PG Speed Option Card with the catch position
as shown by (a) and (b) and fit it precisely to the Option-A connector. Insert (a) first.
5. Pass the spacer through the spacer hole at the card. (Refer to A in the illustration.) Check to be sure that it is
precisely aligned with the 4CN position, and snap it into the proper position. Be sure to press it in firmly until you
hear it snap into place.
