Product Information
The TerminatorTM ZP-MI-WP Power Connection Kit is a heat tracing cable system that can be used for power connection, in-line splice connection, or T-splice connection with MI – Mineral Insulated Heating Cable Sets. The kit includes various components such as wire pins, an expediter assembly, a support cap with an O-ring, a threaded grommet compressor, a grommet, a support base with an O-ring, a junction box lid, a junction box base with O-ring, a nut, banding, terminal blocks with DIN rail, jumpers, junction box cord, blind plug, bracket, screws, washers, and wire pins.
The kit is certified and approved for use in ordinary and hazardous locations such as Class I, Division 2, Groups A, B, C & D Class II, Division 2, Groups F & G, Class III Class I, Zone 1, AEx e II T4-T6; Ex e II T4-T6. The product must be cleaned only with a damp cloth to avoid the electrostatic charge.
Product Usage Instructions
- Choose a mounting method:
- Method 1: Secure the wall mount bracket to the mounting surface using a pipe band.
- Method 2: Secure the wall mount bracket to the mounting surface using screws, washers, and nuts (customer provided).
- Mount the expediter to the bracket using M5 screws and lock washers.
- Crimp-appropriate wire pins (2.5 mm2 or 6 mm2) on MI cable cold lead wires if required as per client/project specification (order separately).
- Route MI cable cold leads through M20 threaded entries. Screw cable glands into the junction box. Do not overtighten to ensure the O-ring is not damaged during installation.
- Center cold lead sleeve inside cable gland. Tighten cable glands until ferrule begins to make contact with cold lead sleeve and a cold lead sleeve cannot be moved by hand. Tighten cable gland 1/8 additional turn or a torque value of 16 Nm (142 lb-in).
- Install user-supplied M20 Earth Tag and Lock Nut to threaded M20 Gland.
- Install M20 blind plug in the remaining M20 threaded entry (if necessary). Additional M20 blind plugs (order M20-B-EXE) will be required if only installing one gland.
- Install M25 power gland (customer supplied) in M25 threaded entry. For in-line splice or 3-phase wye connection, install M25 blind plug (order M25-B-EXE separately) instead of an M25 power gland.
- Mount junction box based on expediter. Make sure to align slots to properly orient the junction box base. Tighten the nut with Terminator-LN-Tool. If mounting horizontally, threaded gland holes must face downward.
- Install power cable (if necessary).
- Install quick-mount terminal blocks and tighten screws (if necessary).
