NOTES FOR FIGURE 1-5
✱ – 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 n36
through n39 (see paragraph 5.17).
●
– Function labels shown for these terminals are determined by factory setting of n40
(see paragraph 5.18).
♦
– Function label shown for this terminal is determined by factory setting of n03 (see paragraph 5.11A).
■ – Function labels shown for these terminals are determined by factory setting of n44 (see paragraph 5.16).
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 Drive END (ground terminal ). Stub and isolate other end.
2. +12V voltage output current capacity of control terminal FS is 20mA max.
3. The Drive does not include overload 1OL; it is a separate item. If local code requires 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. For
Canadian installations, overload 1OL is to be provided in accordance with the Canadian Electrical Code, part 1 and
NEC.
4. Customer to connect terminal to earth ground.
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. An optional DC reactor may be added for harmonic attenuation, if needed. See separate instruction sheet for wiring.
7. If application does not allow reverse operation, parameter n05 , Reverse Run Prohibit Selection, should be set to
“ 1 ” (Reverse Run Disabled), and the Reverse Run/Stop input can be eliminated.
F. Interconnection - 2 Wire
