POWER CONNECTIONS
AC Power Source Grounding
WARNING
Verify that the AC source voltage is switched off at
the breaker panel before proceeding with connec-
tions.
At this time also set either "115V" or
"230V" on the power supply selector switch.
AC Power
The incoming AC source voltage connects to the AC Input
Power Terminal Block located in the lower right of the Ac-
celaterm cabinet (see Figure 7).
First, secure the branch circuit "Ground" wire to the green
grounding screw adjacent to the AC Input Terminal Block.
Then secure the White "Neutral" wire to the neutral terminal
and secure the Black "Line" wire to the line terminal as labeled
on the enclosure.
After the wiring is completed, use a cable-tie to secure the wires
to the cable-tie mount (provided) located below the AC Input
Power Terminal Block.
Note
: Use of a dedicated, un-switched AC power source results
in optimal performance with minimum interference.

Power Limited Wiring Information
IMPORTANT:
Keep power-limited wiring AT
LEAST 1/4" (one-quarter of an
inch) away from the top of the
exposed printed circuit boards,
and away from the Battery Compartment.
Use clear tubing for auxiliary power
"ACC PWR OUT" wiring as shown in
the accompanying image.

Table 1 lists the incoming AC source voltage connections to the
AC Input Power Terminal Block in the USA (see Table 2 for
Europe).
Note
: Knockouts for conduit Fittings are located on the back of
the metal housing and can be used if "hidden cable" installation is
required.
IMPORTANT SAFETY REQUIREMENT: If
the enclosure door is removed, the Ground Strap
may be unbolted--but MUST be REATTACHED
after installation or service is completed. Failure
to Reconnect the Ground Strap may increase the
Risk of Electric Shock.
Backup Battery Installation
1. Place one or two backup batteries (P/N CI-HE0047) into to
the lower right of the cabinet with the terminals on the right
side.
2. Push the terminal of the BLACK lead onto the NEGA-
TIVE (Black) Tab of the battery.
3. Push the terminal of the RED lead onto the POSITIVE
(Red) Tab of the battery.
Note
: Because of the Low Battery Voltage Discon-
nect feature, the Accelaterm will not start to operate
until mains (AC) power is connected.
