Micro 100
7.3.1 Tools and Materials Required
• Slotted-tip screwdrivers for tightening screws on terminal blocks (1/8in or 5/32in (3.2mm or 4mm) wide)
• DC voltmeter
• Refer to local electrical code for wire sizing and routing. Maximum 12 AWG, 90°C wire for AC input and output
connections.
• Liquid tight fitting for AC input/output is for cable with outside diameter range 6.6 - 13.8mm (0.26” - 0.545”).
• Liquid tight fitting for network/dry contacts cable can accommodate maximum 3 cables, outside diameter range
4 –6.5mm (0.16” – 0.255”).
• If used, maximum of 16 AWG wire for wiring the dry contact terminal blocks. Wire stripped length = ~7 mm
(0.275 in)
• 22 AWG max CAT5e cable and crimp tool for RJ 45 connector
• Two open wrenches (size 27mm) for tightening the liquid tight fittings
Procedure:
1. Install liquid tight fittings on the three openings.
2. Hand tighten first, then use the open wrenches to tighten an additional 1/4 turn.
3. Route input wire through the liquid tight fitting on the left and wire according to its label (L-N-G). Torque to 7.0
lb-in(0.8 Nm) using the slot screwdriver.
4. If used, connect the dry contact terminal block and/or Ethernet wire through the liquid tight fitting. RJ 45
connector for the Ethernet connection has to be crimped after the wire is routed through the fitting.
5. Route output wire (max gauge 12 AWG) through the liquid tight fitting on the right and wire according to its label
(L-N-G). Torque to 7.0 lb-in (0.8 Nm) using the slot screwdriver.
The Alpha Micro 100 has a USB port for configuring the unit on site after installation. If the USB connection is to
be permanently installed, the overall length cannot exceed 25 feet. Special crimp tools may be needed to route the
cable and connector through the liquid tight fitting.
Before starting, make sure line power is turned off and the UPS Input breaker and the
battery breakers are OFF.
