Check Power Requirements 
4. Check the power and power receptacles 
provided. System Power Requirements: 
The power requirements are as follows: 
- More than one receptacle may be 
installed on the branch circuit if more 
plugs are required. 
- If the total power requirements of the 
entire system exceed the rating of one 
branch circuit, individual dedicated branch 
circuits may be installed per cabinet. 
Cabinet Power Requirements: 
The cabinet has a line cord with a three-prong 
plug. There must be one single-phase power 
receptacle, as follows: 
- The power receptacle must be a 
three-wire type, with the ground wire 
connected to the ground of the electrical 
system. 
- There must be no attempt to defeat the 
grounding conductor. 
- The power receptacle must not be 
controlled by a switch. 
System Power Requirements: 115 V - The dedicated receptacle should have a 
rating of 120 V, 60 Hz, 15 A 
System Power Requirements: 230 V - The dedicated receptacle should have a 
The 230 Volt power cord for this product shall rating of 230 V, 50 Hz, 1OA 
be in compliance with the electrical codes in 
force within the region of installation. 
5. Attach a warning tag to the plug end of the 
power cord to prevent its accidental removal. 
Fasten the power cord to the cabinet 
securely.

							InskGng the System 
Verify Ground Connections 
2.3 When you have completed Chart 2-5: 
l Ground requirements will be checked. 
l Voltage and resistance between the ground lug and the ground wire will be within 
acceptable limits. 
Check Ground Requirements 
Ensure that ground requirements have been met. The ground wire shall be installed 
in accordance with national and local regulations and/or regulations of other authorities 
having jurisdiction. References: United States of America: NEC - NFPA/ANSl 70 Na- 
tional Electrical Code Article 250. Canada: CEC - CSA C22.1 - Canadian Electrical 
Code, Section 10. 
All circuit commons in the cabinet, and all system hardware, must derive ground from 
a single ground concentration point in one of the cabinets. This point must derive 
ground from a cold water pipe or other equally grounded point, using a #6 AWG 
insulated green wire connected directly between both points. 
The cabinet and associated ducting hardware must not be exposed to any ground 
source other than that described above. AC service wires bringing ac to the cabinet 
must not share an enclosure or raceway with other system grounds, dc power distri- 
bution wires, or signaling wires. All sources of external ground (for example, system 
signaling ground to the approved ground source) must connect only to the system 
single point ground. 
Note: Before installation, an insulated #6 AWG green ground wire must be connected between the 
equipment location and an approved ground (metallic cold water pipe where it enters the building, 
or equivalent).

Cards / Modules 
Install Universal Card and Modules 
4.1 When you have completed Chart 4-l : 
l A Universal Card and the modules to be installed on the card will be unpacked 
and inspected. 
l The modules will be installed on the card. 
l The card will be installed in the system. 
Note: 1. The Universal Card carries up to four plug-in modules: 
DTMF Receiver/Relay Module - has four dual-tone multi-frequency (DTMF) receiver circuits 
and two relays for night bells or alarms. (power rating = 2) 
Music/Paging Module- provides one 600-ohm balanced audio (music) input, a200-ohm output 
to a paging amplifier, 
and one relay contact for controlling an amplifier. (power rating = 1) 
E&M Trunk Module - Interfaces the PABX to one standard E&M trunk. (power rating = 3) 
2. Up to four modules can be mounted on a Universal Card as long as the total power rating is 
10 or less.
