Wiring Input and Output Power
WARNING
RISK OF ELECTRIC SHOCK. The electrical enclosure of this unit must be bonded to the Building
Grounding Electrode for safe operation. Do not use the isolated ground feature without bonding the RPP
enclosure to the Building Grounding Electrode.
As a result of the connected loads high leakage current is possible. Connection to earth ground is
required for safety and proper product operation.
Only qualified service personnel (such as a licensed electrician) shall perform the electrical installation.
Risk of electrical shock.
Note:
Installation of the RPP must comply with the requirements of ANSI/NFPA 75 and National Electric
Code
®
(NEC
®
) Article 645 when installed within a computer room.
Note:
External overcurrent protection and disconnect are not provided by this product, but are required by
codes. Refer to Table 2 for feeder breaker and wire sizing requirements.
Note:
All wiring must conform to national and local codes. Provide sufficient room for routing all power
cables. Route all signal cables separately from power cables.
To wire input and output power to the RPP:
1.
Turn off utility power at the distribution point where the RPP will be connected. Be absolutely sure there is
no power.
2.
Verify that all circuit breakers are in the OFF (O) position. For layout, see Figure 6 on page 12.
3.
Connect a dedicated feeder to provide the three-phase input power to the RPP according to Table 1 and
Table 2, Table 3, or Table 4. See Figure 7 or Figure 8 starting on page 16 for terminal locations.
Cable routing varies with the selected configuration. Route the input cables to the terminals shown in the
following illustrations:
l
Single or Dual MLO RPP with a distribution panel on one side (see Figure 7 on page 16)
l
Single MLO RPP with distribution panels on both sides (see Figure 7 on page 16)
l
Direct Connection Configuration RPP (see Figure 8 on page 17)
4.
The RPP is provided with an isolated ground from the factory, but ships as a non-isolated configuration.
WARNING
RISK OF ELECTRIC SHOCK. The electrical enclosure of this unit must be bonded to the Building
Grounding Electrode for safe operation. Do not use the isolated ground feature without bonding the RPP
enclosure to the Building Grounding Electrode.
As a result of the connected loads high leakage current is possible. Connection to earth ground is
required for safety and proper product operation.
To use the non-isolated ground configuration, connect your incoming ground to the chassis ground
terminal located at the bottom of the unit. See Figure 9 on page 18 or Figure 10 on page 19 for chassis
ground terminal location.
To create and use an isolated ground configuration, remove the jumper that connects the input ground
terminal to the chassis ground terminal. Connect a ground wire through the ground CT (see Figure 9 on
page 18 or Figure 10 on page 19) to the input ground terminal for each input and run a separate wire to the
chassis ground terminal located on the bottom of the unit.
Rearrange or remove the entry plates at the top or bottom of the cabinet as needed.
