[28] When ordering FormC on mechanically held devices, you must also include FormR6 . [29] Transformer voltage codes. [30] Single primary voltage must be specified using the codes shown in Table 16.207. [31] Mechanically held only. Electrically held device has a control circuit requiring a 120 V secondary, therefore, a transformer is supplied. The transformer comes wired to L1 and L2 unless FormS is called for. It is supplied with two primary and one secondary fuse. [32] Photocell mounted on a NEMA 1 enclosure is designed for indoor areas which rely on natural light. Addition of the photocell does not make the enclosure suitable for outdoor (NEMA Type 3R) installations. [33] Available for 24 V, 120 V, 240 V, 277 V and 480 V applications only. [34] For electrically held enclosed devices, the first pilot is wired in parallel with the coil. Operating interlocks are required for all additional pilot lights. Mechanically held devices require operating interlocks for all pilot lights. [35] Donot use Form X for any interlock wired in series with a pilot light, but do specify how the pilot light and interlock are to be wired into the circuit. [36] Electrically held 20 A multipole contactors cannot add interlocks. Additional poles can be used for the same function, however. Mechanically held (Type LX) provide one double throw auxiliary (or status) contact as standard.
