– Indicates components not supplied.
– Main circuit terminal.
– Indicates control circuit terminal.
( ) – Indicates alternate terminal marking, i.e., (R) and L1.
▲ – Function labels shown for these terminals are determined by factory settings of n050
through n056. (see TM.V7N.01)
● – Function labels shown for these terminals are determined by factory settings of n057 through n059.

1. Insulated twisted shielded wire is required.
2-conductor #18 GA. (Belden #8760 or equivalent).
3-conductor #18 GA. (Belden #8770 of equivalent).
Connect shield ONLY AT the Drive END (ground terminal
2. +12V voltage output current capacity of control terminal FS is 20mA max.
3. The Drive's Electronic Thermal Overload function (n036, n037) meets standards set by UL and CUL for motor
thermal overload protection. If local code requires a separate mechanical overload protection, an overload relay
should be installed, interlocked with the Drive as shown. It should be the manual reset type to prevent automatic
restart following a motor fault and subsequent contact reclosure after cool down.
4. Customer to connect terminal
5. If the Digital Operator is used, remote operators, which duplicate functions of its command keys may not be
required. See Figure 4-1.
6. For installation of Braking Resistor or Braking Resistor unit, refer to Appendix 6, "Dynamic Braking Option."
