APPENDIX B - MCH WITH OPTION BOX
The MCH Series drive is available with an Option Box that allows the drive to
accommodate a disconnect switch, fuses and line reactor. Like the Bypass option,
the customer terminal strip is not located in the drive itself, but rather in the option
box compartment, eliminating the need to remove the drive's cover. This simplifies
installation by having all of the control and power wiring in one location.
B.1 CUSTOMER TERMINAL STRIP
A duplicate of the MCH terminal strip. Refer to Section
15.0 - MCH TERMINAL STRIP for a description of the
terminals.
* Terminal 14 and Relay #2 are both controlled by Parameter
52 - TB14/RELAY #2. TB-14 is an open-collector output,
while Relay #2 is a Form C relay.
WARNING!
Do NOT connect 120VAC to this section
of the terminal strip! Severe damage to
the drive will result. This section of the
terminal strip is low voltage DC and
requires dry contacts.
Contains two Form C relay outputs for status indication
(such as Run, Fault, At Speed, etc). The relays are rated
2 Amps at 120 Vac or 28 VDC.
Relay #1 is set using Parameter 54 - RELAY #1.
Relay #2 is set using Parameter 52 - TB14/RELAY #2.

NOTE
Unlike the Bypass option, which restricts the MCH drive to Remote
H/O/A only, MCH drives with the Option Box can be configured for
Keypad H/O/A or Remote H/O/A. Refer to Sections 13.1 and 14.2.
