Operator’s Manual
1: Cabinet Installation
1.1 Pole Mounting
NOTE: Pole mounting the cabinet should be done in accordance with the local agreement
between the cable operator and the utility company.
NOTE: A bucket truck and other suitable equipment, such as spikes and safety harness,
should be used during installation or service of pole-mounted cabinets. To mount the Lectro
CPR
®
UPS to a utility pole perform the following steps:
1.1.1 Install an appropriate disconnect box between the AC power source and the CPR
cabinet mounting point. Wire to power line in accordance with local codes.
NOTE: The disconnect box should have a high magnetic type circuit breaker, capable of
passing short duration inrush currents, and have a minimum rating as shown below.
For 120 VAC 60 Hz units, the service disconnect shall be a high-magnetic type circuit breaker
rated for 20 amperes in the line lead only.
For 240 VAC units, the service disconnect shall be a 2 pole, high-magnetic type circuit breaker
rated for 20 amperes.
For 220VAC 60Hz and 230 VAC 50 Hz units, the service disconnect shall be a high-magnetic type
circuit breaker rated for 16 amperes in the line lead only.
1.1.2 Remove the U-shaped bracket from the cabinet rear panel (refer to Figure 1.1-1).
1.1.3 Use the bracket as a template to mark mounting holes at the desired mounting lo-
cation. If possible, position the cabinet so that the front panel and the external
LED's are easily visible.
NOTE: If attaching to a concrete pole additional mounting hardware will be required for the
installation. Lectro does not provide the metal bands required to mount to a con-
crete pole. This hardware can be obtained from a CATV hardware supplier.
1.1.4 Drill 11/16" (17.5mm) holes in the pole at the marked locations.
1.1.5 Attach the bracket to the pole using 5/8" (M16-2.0) hardware (not provided). Make
sure that the head of the bolt is next to the pole bracket and the nut is at the rear of
the pole. Tighten securely.
1.1.6 Raise the cabinet and set into place on the bracket already attached to the pole.
The slots on the pole bracket should be pointing downward so that the cabinet will
slide onto the bolts on the pole-mounting bracket. Attach the cabinet using the
hardware provided. Tighten ALL the bolts securely.
1.1.7 Confirm the availability of a suitable ground rod at the base of the pole. If required,
drive a ground rod according to local codes.
