1.4 . 5 I nte r c onn e c tio n – 2-W i r e C ont r o l Oper a t ion - Figu r e 1 -3.
Notes referred to in figure 1-3.
✱ – Indicates components not supplied.
✱✱– Branch circuit protection (circuit breaker or input fuses) must be supplied by customer.
– Indicates customer connection terminal. Wire only to terminals shown. Note that not all terminals
shown are available in all ratings – see Tables 1-1 and 1-2.
( ) – Indicates alternate terminal marking, i.e., (R) and L1.
▲ – Function labels shown for these terminals are determined by factory settings of parameters
H 1 - 0 1 through H 1 - 0 6 . See paragraph 5.32.
● – Function labels shown for these terminals are determined by factory settings of parameters
H 2 - 0 1 through H 2 - 0 3 . See paragraph 5.33.
♦ – Function labels shown for these terminals are determined by factory settings of parameters
H 3 - 0 1, - 0 4, - 0 5, - 0 8, & - 0 9 . See paragraphs 5.19 & 5.30.
■ – Function labels and signal levels shown for these terminals are determined by factory settings
of parameters H 4 - 0 1 & H 4 - 0 4 . See paragraph 5.31.
1 . If only a remote Manual Speed pot (1RH) is used, 3SS is not needed; in that case, a jumper must be
added between terminals 5 and 11. This jumper will override both the Auto and Digital Operator
frequency references, regardless of the programming of parameter b 1 - 0 1 . If you are using a remote
speed command or the Digital Operator, DO NOT install this jumper. See paragraph 5.19.
2 . The Drive Electronic Thermal Overload function (parameters L 1 - 0 1 , L 1 - 0 2 ) meets standards set by
UL and cUL for motor thermal overload protection. 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.
3 . 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. Stub and isolate other end.
4 . Digital Operator is standard on every drive. Remote operators, as shown, may not be required.
5 . Customer to connect terminal to earth ground (100 Ω or less, 230V; 10 Ω or less, 460V and 600V).
6 . Wire only one of the inputs as an Auto Reference. If H 3 - 0 9 is set to “ 1F “, terminals 13 and 14 are
added for the internal frequency reference.
7 . If the Dynamic Braking (DB) option is used, wire per Appendix 6 instructions.
8 . An optional DC reactor may be added for harmonic attenuation, if needed; see separate instruction sheet
for w i r i n g.
9 . If application does not allow reverse operation, b 1 - 0 4 , Reverse Run Prohibit, should be set to “ 1 ”
(Reverse Run Disabled), and the Reverse Run/Stop input can be eliminated.
1 0 . If supplying the drive with DC voltage instead of 3ø AC, remove jumpers from terminals
l1 and l2
and connect a separate 1ø AC supply to l1 and l2 instead.
1 1 . Use
l1 (R) and l2 (S) for single-phase input. Note that for drives up through GPD515C-A064, -B034, and
-C032 (CIMR-G5M20151F, 40151F, and 50221F) must be derated by 50%. Consult factory for derating
of larger drives.
